Tyler Reid is co-founder and CTO of Xona Area Techniques. Beforehand, Tyler labored as a Analysis Engineer on the Ford Motor Firm in localization and mapping for self-driving vehicles. He has additionally labored as an engineer at Google and as a lecturer at Stanford College, the place he co-taught the GPS course. Tyler acquired his PhD (2017) and MSc (2012) in Aeronautics and Astronautics from Stanford and B.Eng. (’10) in Mechanical Engineering from McGill.






lilly: Hiya and welcome to the Robohub podcast. Would you thoughts introducing your self?

Tyler: Hiya and thanks once more for having me on at this time. So I’m Tyler Reid and I’m co-founder and CTO of Xona Area Techniques.

lilly: And might you inform us somewhat bit about Xona Area Techniques?

Tyler: Yeah, for certain. So Xona Area Techniques is an organization centered on, mainly constructing industrial GPS satellites.

So actually shifting away from the mannequin of, , these type of authorities operated programs like GPS which have a type of very particular, , authorities oriented mission. Shifting in the direction of a system that’s, , commercially pushed round type of wants of economic customers and, , going extra in that course to type of assist these customers going ahead.

lilly: And what do you assume are type of the advantages of going industrial with a GPS kind expertise?

Tyler: Yeah, for certain. So to talk somewhat bit about my background and type of the place a few of that is coming from. So, so I type of got here from the world of, , GPS and began actually in grad college on that facet of issues.

And transitioned after grad college to working in type of trade analysis. So I used to be working in autonomous automobiles, working with these programs and type of seeing these programs actually closely depend on, on GPS and type of what’s on the market at this time. And actually the cutting-edge of the expertise was, , having third get together firms mainly ship correction data for the GPS satellite tv for pc.

So the data coming from GPS straight was actually not fairly on the degree that it should be to assist these, , programs like self-driving which might be actually making an attempt to get all the way down to the centimeter degree location to, to, , drive themselves on the highway. and so to get to that degree, you had type of these firms whose complete type of position was to ship, , higher orbit, higher clock data than what GPS provides you straight to essentially drive these errors all the way down to that type of that centimeter degree.

And due to the best way the system was architected, which actually wasn’t, , meant for use this manner, it led to. , the fragilities in that type of sign. So if you begin to drive beneath bushes or in sure environments, you’ll usually lose that type of centimeter degree location. And it simply, it type of left some, I suppose, holes to be crammed by, by one thing else.

And what that’s one thing else was was, was a part of my job to determine, okay. , was it possibly terrestrial based mostly answer? Is it laptop imaginative and prescient answer is a type of the entire above. And, , with my background coming from, , satellite tv for pc navigation and GPS and type of seeing how these programs have supported, , some security, essential functions like civil aviation, which is, , a part of what my type of, the thesis work was in and type of fascinated with how that might evolve to assist, , a few of these floor programs like autonomous automobiles, but additionally uAVs and, and type of different type of,type of autonomous programs going ahead, that type of actually led to this.

Okay, effectively, how can we alter issues on the house facet moderately than simply making an attempt to make use of what we’ve from these type of authorities programs to, to type of, , fill the gaps, I suppose. And so from a, from a industrial perspective, , what are a few of the advantages that you just get there? Nicely, actually you’re not tied to type of the, the system that, that the federal government offers for you, which, , is type of static. It’s there for a purpose. And it, , it’s actually a unbelievable system and it, it helps billions of customers. It has created type of all, , all these use instances that we, , I’ve, I’ve a horrible sense of course.

So, , figuring out type of the blue dot to search out my method house has, has been, , extremely helpful. However, , as we take into consideration shifting away from, , people who can. use that data to type of get near the place they should go after which type of end the job themselves and, and going in the direction of autonomous programs that basically depend on that blue dot being, , precisely proper the place it’s to, to, to essentially get to that time type of on their very own, with none enter from, from any people.

There actually is type of that there’s type of a leap that should occur there by way of, , The sorts of ranges of, reliability and likewise, , precision that, that these programs assist. And so fascinated with this from type of the industrial perspective, , what are you able to present and, and changing into type of from an aerospace background, , how are you going to, , evolve this house phase to essentially be centered on the, on the industrial facet.

And so. A few of the advantages. There’s you, you simply, , you’ve gotten type of a clean slate in a way. And so you can begin with, , what do we actually have to assist customers on the bottom? After which we are able to begin to architect the system, , round a few of these, , rising wants moderately than, , supporting issues from in many years, previously, I suppose.

lilly: And by way of like attending to that centimeter degree accuracy do you assume that many of the technological developments are within the house facet or like, do you intend on doing does Xona house programs plan on doing numerous that error correction, like related error correction kind stuff and like the total stack?

Tyler: Yeah, that’s an excellent query. And I’ll say in some sense, we’re not inventing, we’re not reinventing the wheel. We’re type of, , we’re utilizing numerous the strategies that’s been effectively established by the type of excessive precision GNSS trade, which has supported traditionally [00:05:00] issues like surveying issues like mapping, precision agriculture, , are huge customers of, of this sort of expertise.

And so actually type of constructing on the shoulders of giants in, in that respect. , how, how are of us getting excessive precision at this time and type of, , evolving that to kinda the following, the following type of, , what would possibly the following type of, house infrastructure seem like to, to make use of these strategies and type of make them even higher for folk.

And so, , if you have a look at the type of errors that stack up in GPS, you’ve obtained. The ambiance is an enormous one, , as these alerts refract by way of the completely different layers of the ambiance, notably the ionosphere and troposphere, , that that’s a, an error that type of manifests itself on the person degree, but additionally simply the orbit and clock data coming from the satellite tv for pc, as a result of finally you’re triangulating your place from, , a number of completely different factors in house.

You higher know very effectively what these factors have been, cuz in any other case you’re not gonna know very effectively. What, what your place is on the finish of the day. So you must work out a technique to get, , centimeter degree, , orbital data of the GPS satellite tv for pc, as a way to in flip type of get your place to the type of centimeter degree as effectively.

And so how do you try this with type of, , as we take into consideration this sort of evolving from, , the type of, the strategies which have been used previously to, , what is perhaps doable, sooner or later? Nicely, it seems that one of many huge type of inputs to that system, By way of how rapidly you may get from type of meter degree place all the way down to type of the centimeter degree is how rapidly the satellites transfer overhead.

And it seems that in the event you make it such that the satellites transfer overhead in a short time, there’s simply much more data in that type of very fast go than you’ve gotten from these additional satellites, which historically are type of medium earth orbit to assist that convergence get you from type of a tens of minutes type of place to a minute or much less type of place. And, and naturally there are strategies which might be making that all the time higher on a regular basis from a medium earth orbit perspective. , if you’re utilizing type of the standard GSS satellites to, to get to that top precision, there are strategies evolving to, to get there quicker and quicker.

However when you have that very quick type of movement throughout the sky, it simply makes these strategies even higher than that they’d be in any other case. And in order that’s, that’s, that’s an instance of the type of factor you are able to do from a, , industrial house phase perspective to, to only type of carry extra functionality to, to of us on the bottom.

lilly: And so when you have, in the event you get higher efficiency from having shifting automobiles, and so that you’re having them at decrease orbits, you additionally want like three or so to get your place does having greater than that assist? And what number of, like what number of complete satellites do you assume is gonna be the correct quantity?

Tyler: Yeah, that’s a very good query.

What it comes all the way down to is, , the extra satellites, the higher , that’s type of the easy query, the easy reply there, however mm-hmm, actually we’re, , actually leveraging an analogous approach that’s been used from, from GPS, which is named trilateration.. And what that’s, is there’s mainly 4 unknowns in that system and the 4 unknowns or your X, Y, Zed (or sorry, that’s Canadian – XYZ) and, and time, and, and the rationale time is type of an uncertainty there’s that the best way you calculate vary to the completely different satellites is that the satellite tv for pc sends a sign and the sign mainly says it was this time after I despatched it, the sign takes a while for it to journey to you. You obtain it a while later.

And so the distinction between the time it was despatched and the time you acquired it’s the, mainly the time of flight of the sign. And, and that point multiplied by the pace of sunshine is, is the vary to the satellite tv for pc. So, in the event you try this to a number of satellites, now you’ve calculated one thing that appears like a variety to you as a result of it’s, , that, that point of flight to a handful of satellites, you’ll consider, , in 3d house, you want, you’ve gotten three satellites, three unknown, , XYZ place.

, what’s the, what’s that fourth unknown, , why do you’ve gotten that further unknown there? And that’s since you don’t know precisely what time it’s if you acquired it, you acquired it at some native time, which is, , no matter time your cellphone says, however , how, how correct is that on the finish of the.

Tyler: And if you consider the sensitivity of the issue of how correct you really want to know your time to do to calculate these ranges? Nicely, it seems. One nanosecond of time, uncertainty is, is a foot or 30 centimeter. And so it stacks up very, in a short time if you’re speaking about type of nanosecond of, of time information, and it’s very laborious to, to take care of nanosecond type of timing in your cellphone.

Your time, time in your cellphone is extra on the type of microsecond degree. More often than not, that’s type of the place it must be to, to do its job, which is type of telecommunications and all these things. However in the event you’re speaking about doing precision ranging. You actually need that type of nanosecond type of functionality.

And so moderately than, , having to carry an atomic clock with you on a regular basis to type of preserve your time at that type of, , very excessive, exact degree, you simply resolve for it as a substitute. So that you add a fourth satellite tv for pc and now, , you get the three dimensions and that point dimension to, to get your place type of all the way down to, , our expertise at this time is extra type of at that meter degree, however , that type of handful of nanosecond type of uncertainty type of level. And so, , going, in order that type of minimal quantity you’ll want to get some type of place data is, is 4. It does assume you don’t have any different [00:10:00] sensors or, or nothing else like that.

So in the event you simply type of solely have your type of GPS receiver and nothing else 4 satellites is type of the naked quantity you’ll want to, to get that first place. so , what number of extra do you’ll want to do the job? Nicely, effectively, you need extra than simply 4 to type of be strong to that. And, and the reason being, is you begin type of shifting round on this planet.

You, you might not all the time have overseas view in the event you type of have, you’re assuming you’ve gotten full view of the sky, all it takes is a constructing to dam one a part of the sky and also you solely have three. So you actually wanna design that system to, , have greater than 4 in view always that you just have been on earth.

So that you just’re strong and issues like buildings being in the best way, bushes being in the best way. , additionally simply, usually it’s, , you’re gonna have simply one thing, that’s gonna provide you with larger precision when you have much more satellites in view, trigger you’ve gotten extra measurements obtainable to you and.

The the proper of quantity that the majority, I suppose I’ll say GNSS programs have come to at this time is extra at that type of 10 or 12 variety of satellites in view. And that’s what GPS has at this time. That’s what the European Galileo system has at this time. And so type of in addition to the, the Russian, sorry, the Russian GLONASS, and Chinese language Beidou programs are, are type of in that related variety of satellites.

And so. Tenish or so satellite tv for pc is about the place you need be type of at minimal and the extra satellites you must simply higher, it’s gonna work in additional locations, I suppose.

lilly: Mm-hmm if it’s 10 or 12, like seen out of your system without delay, I assume they don’t have protection of in every single place unexpectedly for the total constructed out constellation.

Tyler: Yeah, that’s an excellent query. And so when, if you’re speaking about type of the GPS system, which is deployed in a medium Earth orbit, which is about 20,000 kilometer altitudeor so. That system has about 30 satellites to attain that objective. In order that’s about what number of satellites that if you deploy type of on the excessive orbit that you just want. We’re concentrating on a decrease orbit than that at this time, which is extra type of within the thousand kilometer vary..

So, so being that 20 instances nearer to earth, it seems that satellite tv for pc footprint simply shrinks and shrinks and shrinks. Trigger you’re simply a lot nearer to, to earth. And so that you want extra satellites to get the identical quantity of protection. So we’re concentrating on a couple of 300 satellite tv for pc constellation or so.

lilly: OK. talking in regards to the time of flight measurements, is there any, like, would you contemplate and what are the benefits and downsides of, as a substitute of doing the a technique time of flight and having to maintain observe of all that synchronization with doing type of a two-way ranging, the place your system is the one pinging?

Tyler: Yeah, that’s an excellent query. And, and this was one of many unique trades that was performed when of us have been growing GPS. And so some folks smarter than me had, had put numerous thought into, , why you would possibly. Do this sort of system over say this sort of two-way time switch system.

Yeah. And a few of the benefits there, the principle one is de facto that in case your system has to ping again to the satellite tv for pc, it does two issues and certainly one of them is that it, it, it’s an even bigger energy draw in your system as a result of your system is having to type of ship a radio sign {that a} satellite tv for pc has to obtain.

And in order that that’s one piece. And the opposite piece of it’s that the satellites then additionally should, be capable to obtain all these alerts from a number of customers. And so you find yourself placing a constraint on the capability of the satellite tv for pc within the sense that now that satellite tv for pc has to get pings again from all these of us which might be utilizing it, possibly only some hundred or a number of thousand folks without delay can use it, which is, it finally ends up being type of a limiter on the variety of of us who can truly use that system.

Whereas in the event you use this sort of a technique time switch system, the place though you do want type of an additional satellite tv for pc in view to resolve the issue. You possibly can in idea type of, , assist an infinite variety of customers. And so, which is the case of GPS at this time, the place we see it supporting, , billions of customers and you’ll, , add as many gadgets as you need with out having that constraint.

In order that, that that’s the large one.

lilly: Yeah, that is sensible. So in case you are at this decrease orbit and GPS satellites, The normal authorities funded ones nonetheless exist above you. Can you employ them to raised observe your satellites?

Tyler: Yeah. completely. And that turns into one of many inputs, to the system, for certain.

As a result of, and folk have performed numerous stuff in, in low Earth orbit, supported by GPS as a result of a part of the service quantity of, of these GPS is to assist functions in decrease orbit. So you possibly can consider earth imagery, the worldwide house station, all these sorts of parents are, are utilizing that. That being mentioned, we’re designing the system to be GPS impartial.

Simply because there’s numerous curiosity from that from of us to have that functionality, you’re not essentially totally depending on, , this different system that you just’re augmenting having some potential to type of function, with out enter from that system is, is advantageous in some methods, however it’s there and it’s a nice enter to the system that, that we’re placing collectively.

Tyler: And so it is sensible to, to incorporate these measurements a method of simply making the system extra strong on the finish of the day.

For a person, like for the typical individual with a cellphone, will the GPS receiver that I have already got on my cellphone work together with your system instantly? Or are there modifications that should be made?

Tyler: Yeah, that’s a very good query too. And it, there’ll probably should be modifications to, to the system in your cellphone at this time, however we see that as a part of the type of pure evolution of how the GNSS chip units are evolving and. Considered one of our, I suppose our normal strategy to this isn’t to compete with the GNSS receiver producers it’s to work with them, to include [00:15:00] our service into their gadgets.

And, and so actually working to, , make it, make that type of adoption as much like what say including a few of the new constellations which have come on-line over time is like, so, , initially there was solely GPS chips after which there was GPS plus BLONASS chips, after which there GPS plus Galileo plus BLONASS plus Beidou chips.

And so actually making an attempt to type. Proceed that evolution of together with a few of these, these new programs into these chip units. And so working with the, the GNSS receiver producers for most probably the following technology of gadgets, as a result of notably the type of ASIC gadgets that you just discover in your cellphone are, are so optimized for a particular software that becoming in new issues is, is an enormous problem. For a few of the extra, I’ll say, this, type of, excessive efficiency receivers which might be on the market at this time which might be supporting a few of the excessive precision functions on that facet of issues, that there’s some, risk of, having that be extra akin to a, a software program replace than,than type of a brand new system.

lilly: Fascinating. I needed to pivot somewhat bit and speak extra about, a few of your work with autonomous automobiles and at like, there’s clearly a transparent, like interface between these two issues, however what are a few of the similarities and variations by way of like the way you truly are fixing technical issues or the autonomy on the automobiles and the autonomy on the satellites or any of that type of factor?

Tyler: Yeah, that’s an excellent query. So I’ll say half, possibly I’ll, I’ll take. Give somewhat little bit of historical past of type of the place a few of the, I suppose, type of my time in autonomous car type of led to this curiosity in type of pursuing this sort of satellite tv for pc navigation facet. so after I entered the type of autonomous car realm and I used to be working at Ford motor firm on the time, a part of my position at that at the moment was type of a mixture of expertise scouting and elementary analysis .

In expertise scouting, it was actually working with the startups, notably in Silicon valley, but additionally different expertise firms as effectively, to essentially set up, , what’s the cutting-edge in, , location and mapping applied sciences for. At first was, , centered on type of these degree 4 degree 5 totally autonomous automobiles, nevertheless it was additionally type of supporting a few of the degree two degree three type of, driver help programs as effectively.

And type of as soon as establishing that type of the place, what the state of they’re, the expertise was a part of that and type of, making an attempt to establish which of them have been a few of the market leaders was to ascertain, , what are the necessities for these programs finally, and which one is type of closest to the place the necessities ultimately should be.

So, , what are the situation necessities for, for autonomy? And that turned out to be a, a a lot tougher query than I believe we initially thought, I believe of us have been like, oh, , 10 centimeters appears to be the suitable quantity, nevertheless it was usually type of unjustified. It was type of a ten centimeter appears to be a quantity the place the system fails the least.

In order that looks as if a great place to begin. However we needed to type of take a step again and say, okay, essentially, , what do these automobiles really want by way of, , a bounding field, in the event you wanna consider it that method round a car to say, okay, that is the situational consciousness that I want to do that, this sort of household of duties or this sort of household of duties.

And actually what it turns into is there’s some functions the place you’ll want to know what highway you’re on. Some functions you’ll want to know what lane you’re in. And a few functions we actually have to know, , to the centimeter, to have the ability to steer the automotive throughout the lane and type of, , get to the place you’re going.

And it turned out that, , seeing type of the place, the place the necessities finally wanted to go and type of the place the cutting-edge expertise was. There was no less than in my thoughts, very a lot a niche of, , the place, the place issues, type of stood at this time. And that led to the motivation, no less than from, from my facet to say, okay, effectively, what’s one thing we are able to do from the infrastructure facet to assist fill that hole?

As a result of one of many developments that was occurring within the autonomous car trade, no less than within the time after I was, was there was. , the, the type of variety of sensors, the quantity of compute on the automobiles was making these automobiles in some sense, prohibitively costly. , you had a lot {hardware} on the automobiles, the automobiles have been type of these type of million greenback, very specialised type of automobiles.

It simply didn’t scale that effectively, whereas in the event you can offload a few of that to the infrastructure facet, to assist a number of automobiles, , that appeared to make extra sense to me no less than. And, and so this went again to, okay, effectively, what, , being type of somebody from an aerospace background, place, navigation background, considering, okay, effectively, what can we do from an area, infrastructure facet to assist this sort of place navigation and, and time drawback.

Tyler: And so I believe by way of, , the place these two issues are, are type of coming collectively is, is de facto seeing this from a okay, how can the, this infrastructure assist the wants of these programs? There are, in fact, some, some crossover between the 2 within the sense that there are applied sciences which might be, I believe gonna be used on each within the sense that, , you need these satellites if you’re deploying a big constellation to have, , a excessive diploma of autonomy about themselves by way of fault monitoring by way of integrity monitoring.

As a result of finally you’re making an attempt to. , assist these, , security, essential programs within the, within the case of automotive. And so having the, , numerous that type of fault checking, type of performed in an autonomous method. In order that be caught in a short time, it turns into crucial, however there’s additionally simply elementary issues like, , essentially a car when it’s doing its navigation and positioning is working [00:20:00] one thing like a Kalman filter or some one thing that’s combining these measurements.

These sorts of issues are gonna be working on, on the satellites for orbit dedication. So it’s a distinct context of drawback, however , essentially an analogous software in, ultimately of the day. And there’s additionally some parts of, I believe, collaborative, , infrastructure as effectively. So if you consider, , self-driving automotive driving by itself with a complete bunch of sensors on it, effectively, that’s.

You’re type of simply making an attempt to switch one human in a automotive. Perhaps that’s not the easiest way to do it. Perhaps there’s some benefits to having automobiles work collectively in a collaborative method the place, , a car that’s maybe down the highway from you possibly can share sensor data or situational consciousness data as a way to set up that situational consciousness, , on the metropolis degree the place you possibly can see round corners, see aroundyou know, different obstacles that you would be able to’t see to type of get to the purpose the place you’re driving as safely, as , all of the people mixed on the highway, moderately than type of only one human can solely see one a part of the view of the world. And so I believe there’s a component of that that may discover its method into the, the house type of the house and type of floor segments that assist these type of house programs going ahead.

Y know, how can these programs work collectively to search out faults in one another the place , these, these sorts of concepts that I believe are, are fascinating as effectively.

lilly: Yeah. that’s a very good level. And I’m somewhat in listening to extra about this concept of getting the satellites collaborate and type of what are probably the most technically difficult or technically promising parts of that.

Tyler: Yeah, that’s an excellent query as effectively. There’s, I’ll say there’s loads occurring in, within the house trade now, I believe even in comparison with, , even 5 or 10 years in the past that they actually make numerous this doable. And , one of many huge ones is simply the size of the constellations being deployed as of late.

And I believe that that’s enabled by. Just a few issues just like the decrease value of entry to house, , SpaceX is I believe one of many extra seen gamers there, however there are in fact others and the opposite is simply, , completely different satellite tv for pc manufacturing strategies. So constructing satellites extra such as you would construct a automotive on an meeting line moderately than type of these bespoke type of one satellite tv for pc’s in a room the place you’ve gotten a bunch of individuals type of placing stuff on it.

It’s a reasonably, it’s only a completely different mannequin of, of assembling this stuff. And. Once we have a look at the sorts of applied sciences that I believe are, are type of coming into that type of satellite tv for pc realm which might be possibly even borrowed from locations like automotive, the place, , particularly if you’re speaking about meeting and, and testing, , making one thing that’s, , very strong in, in type of excessive volumes that.

Kind of brings this stuff collectively. I believe that, that that’s no less than one instance of, , I believe the place these two industries can study from one another, I suppose. Uh, okay. So I believe so far as, , autonomy on the satellites and the power to type of collaborate with one another, I believe one of many huge, the, one of many huge parts of that’s the potential for the satellites to only speak to one another, to start with. And so the power to type of go data.

Between satellites is, is I believe a, an enormous milestone type of as a part of that. And I believe one of many enabling applied sciences there that we’re, that we’ve seen type of come to mild is the, this potential of type of having inter satellite tv for pc communication hyperlinks between these satellites. And there’s been numerous, I believe development of in each optical and radio, type of,, intersatellite hyperlinks between that to go that data round.

And I believe that, that, I imply step one to collaboration as it’s an automotive as effectively, it’s simply establishing I believe that that’s customary and likewise the type of potential for this stuff to go data between one another. I believe there’s actually been challenges in automotive on that facet with, with establishing requirements, with issues like vehicle-to-things, so V2 V to X, so car -to-stuff, or different car type of communication hyperlinks and establishing simply, , what’s the spectrum that we shared? What’s the protocols for these type of communications? And I believe it’s, it’s one factor to do it in a type of. , if one say automotive OEM decides to do it a sure method and so they can try this between all their automobiles.

It’s one other to do it type of throughout automobiles of all completely different producers, type of in a standardized method. And so I believe that that’s that’s one of many challenges is simply type of establishing, establishing type of the expertise and the type of requirements for that communication throughout, throughout satellites.

And naturally, as we take into consideration deploying our system, we expect largely of type of communication between the satellites that we’ve. But it surely’s fascinating to consider, , potential, , cross type of, communication between different platforms as effectively.

lilly: Yeah. And do you intend on, do you anticipate having optical or RF cross hyperlinks or each in your system?

Tyler: Yeah, I believe that’s one thing that we’re exploring. So I believe it’s one thing that’s on the desk, however I believe that we’re nonetheless in, we’re on the section proper now the place we’ve deployed our first demonstration satellite tv for pc. And so for the demonstration satellite tv for pc, it has, I’ll say one thing that’s akin to, , inter satellite tv for pc hyperlink, which we’re exploring between this, our type of second launch that’s coming, subsequent yr.

And so. That’s one thing that we’re exploring as a part of the long run deployment of the system, however the type of earlier iterations might, it might not be required. So it’s, it’s one thing that we’re exploring and it’s one thing we’re keeping track of, however, it it’s possibly not essentially one thing that’s essentially essential to the system working.

lilly: Nicely, congratulations in your first launch and your upcoming second launch. I needed to pivot somewhat bit extra truly, and listen to a bit about, a few of your [00:25:00] analysis again if you have been within the academia and like how that led into, each your autonomous car and your present jobs.

Tyler: Yeah, that’s a, yeah, that brings me again

So to return to, I suppose my days as a grad scholar. So, the lab that I labored in was the GPS analysis lab at Stanford college. And it was a very nice surroundings for me. It was one which centered, , very a lot on that type of place navigation drawback, but additionally one which centered somewhat bit on, , operational tasks for the FAA, in addition to we have been working with the federal aviation administration.

, assist these type of security, essential programs, , plane utilizing GPS to land plane utilizing GPS in flight. so, , fascinated with issues about, , what are security essential use instances of place navigation and time particularly in transportation. And on this case, it was supporting civil aviation.

And in order that was a very, that was a very fascinating surroundings for me, since you might see the work that you just’re doing straight impacting that trade. In some variety of years, it wasn’t that the grad college students have been engaged on issues, , straight type of in operation, however that it wasn’t too far-off from type of essentially seeing the lifetime of operation.

So I believe from a, , how that led into type of the, the work that I used to be doing, type of within the autonomous car world. I believe that fascinated with the issue of, , what are the type of ranges of situational consciousness that automobiles want by way of place navigation and time, , what’s the degree of type of security and integrity that these programs want?

Actually utilizing that type of framework in a structured technique to develop, , what would possibly that framework seem like in automotive, which was type of new to that concept of getting place and knowledge as a part of that type of security, essential enter to, , steering the car and, , type of protecting the human partially within the loop or completely within the loop, that are type of issues that aviation had type of labored by way of as a result of there are occasions the place the plane will fly itself.

There are occasions the place the plane type of has the pilot within the. So it’s, , fascinated with these sorts of issues in that framework. And I believe that that, that type of facet of issues straight led to the work that we did in type of establishing, , what is perhaps the framework and necessities for these automobiles going ahead.

, fascinated with this in type of a civil aviation strategy, as a result of. And if you examine the numbers, , civil aviation actually has the most effective observe report that you would be able to give you by way of security and, , per miles traveled with people and type of all these by all metrics. It’s it’s method safer to sit down at an airplane than it’s to sit down in a automotive that that was that’s usually the, the takeaway and a part of that’s the effectively that people have loads much less people in vehicles have loads much less coaching than people in plane who’re working these issues.

And so it’s a. That that’s simply essentially a kind of variations. And, and, and a part of that’s, is that if one thing goes improper in an plane, such as you higher know what to do rapidly, whereas one thing goes improper in a automotive, you possibly can pull off to the facet of the highway. And so, and so simply essentially some, some variations there, however I believe that that’s, that’s one of many huge ones I believe was, , bringing a few of that framework from, , aviation to automotive and fascinated with these, these issues in that method.

And the opposite facet of that was the type of. , the type of industrial GPS and GNSS facet of that. So, , transitioning from, , , the federal government system that helps, , all these billions of gadgets and created all this sort of, , financial improvement and type of all these developments, and fascinated with how that may evolve type of within the so-called type of new house age, which is the age if you consider issues like SpaceX and, , these type of gamers which have actually challenged the type of so-called conventional aerospace, which is, extra the type of, , if you consider that as type of these longer timelines, very threat antagonistic type of gamers. And, and, , fascinated with how, how would possibly a few of these type of new strategies or new approaches in house, fascinated with these type of mega constellations which might be being proposed by, on the time they have been being proposed, it didn’t but exist. So we’re speaking about type of Starlink and OneWeb and , all these type of gamers, which appeared type of like science fiction on the time, this was type of within the 2015 type of period earlier than numerous these things launched something or had been deployed.

These have been all type of concepts on. , a few of that work was type of the basic, okay, effectively, what would possibly you be capable to do with one thing like this? If, if these type of satellites truly come to exist, if the launch prices truly come down, , what is perhaps some functionality that you could possibly leverage from that type of house infrastructure?

So in the event you might deploy one thing like that for place navigation and time, , what would possibly that seem like? What would possibly the capabilities be? However I believe at that time it was type of a okay, effectively that, that’s an fascinating drawback, however, It was in some sense, missing motivation. It was type of a, okay, effectively, who desires this?

, what do we want this for? GPS works very well. Each, I believe on the time it was like, effectively, we’ve performed it. , GPS is in everybody’s pocket. What else might you need? And, and it wasn’t till I, I labored in an trade the place GPS, because it stood, wasn’t fairly sufficient for, for what they wanted that I type of these dots linked at no less than on my facet to, to see, okay, effectively possibly this sort of strategy might assist this different facet as effectively.

So in some sense, , there’s, I suppose studying from each side and type of linked this stuff collectively, I suppose.

lilly: Yeah, that makes [00:30:00] sense. It’s very fascinating to listen to the way it all connects. we’re developing on time, however I do have one final query. which is, are there different industrial gamers making an attempt to get into the GNSS house?

Like, do you’ve gotten any actual rivals proper now?

Tyler: Oh, there, certain. There’s undoubtedly of us on the market. So we’re not the one ones doing this. I believe that they’re, I gained’t title all of them by title. Trigger I, I can’t converse to everybody’s plans on the market, however I can converse to a, a number of normal developments that, that we’ve seen.

And one is that, , the, the oldsters on the market who’re constructing these type of mega constellations for communication functions. So, , the web from the sky type of of us are undoubtedly occupied with offering one thing. I believe that it, it seems very completely different from, from what we’re working in the direction of, which is extra of a , , particular excessive efficiency, , GNSS, P and T type of service, which seems loads like what you have already got in your cellphone by way of chip set, by way of these sorts of, , antenna, these sorts of things. Whenever you have a look at a few of the, , the communication, programs, , actually they’re a very completely different frequency bands.

Their person terminals are normally fairly massive as a result of we want a reasonably large antenna to type of, full the hyperlink finances to get the type of information charges that they’re speaking about. It, it they’re, they’re actually fascinated with it, however I believe that, , their major objective is de facto, , communication, nevertheless it’s type of a, oh, we are able to, , we’ve this technique, we are able to in all probability assist some type of navigation as effectively.

Not less than that’s what we’ve seen to date. So I believe that that’s, that’s one of many rivals on the market. By way of others, we’ve seen some fascinating stuff occurring from truly one of many main, automotive OEMs on the market, which is a Chinese language firm referred to as Geely. They’re truly constructing and deploying their very own constellation, which is de facto to assist autonomous automotive actions. It’s, , communication navigation type of multi functional package deal. And in order that’s, , seems to be, , one of many huge, one of many huge gamers on the market. And so there there’s actually another firms as effectively. There are some established providers on the market at this time, for instance, from Iridium, which is offering some P and T providers at this time.

And there are different satellite tv for pc providers offering extra correction providers. So issues which might be correcting, offering extra data to type of praise the GPS sign, however not an extra, , type of ranging or GPS sign itself. In order that’s, I believe one of many, one of many main variations there.

Tyler: So, and we, we, and I believe since we’ve been doing this, we’ve seen some others, another firms type of suggest some related issues as effectively. So I believe we’re, it seems to be that, issues are heading on this course, I suppose.

lilly: Nicely, yeah, it’s undoubtedly an thrilling house to be in an thrilling time.

And. A extremely fascinating thought. Thanks a lot for talking with me.

Tyler: Yeah, my pleasure. Thanks once more for, for the invitation to talk right here at this time. And, yeah, this was nice dialogue.
