Highlights from Mr. Epperson’s presentation:

I’ll go fairly shortly via a few of these slides so we are able to get to some questions. My agenda is to give attention to the varieties of issues that we use sensors to resolve at Vigilant Aerospace.

We’re an organization that develops security techniques for unmanned plane. That’s our focus.

We construct expertise that’s based mostly on a few licensed NASA patents that Ricardo [Arteaga], who works at NASA Armstrong, was the inventor of. We love working with NASA

We’re going to speak in regards to the significance of sensors and security for unmanned plane operations We’re going to speak particularly a couple of perform known as detect-and-avoid and why sensors are important to that and why it’s important to the business. And, we’re going to speak about integration of unmanned plane into the US nationwide airspace, which is a very thrilling subject proper now.

Let me discuss what detect-and-avoid techniques often have as elements and discuss some examples together with our explicit merchandise. We’ll discuss some latest tasks that we’ve executed to develop our detect-and-avoid system and to make the most of and take a look at quite a lot of sensors. Then we’ll discuss some future developments happening with these kind of sensors.

To begin with it’s essential to know the issue that we’re making an attempt to resolve with sensors. The business proper now for unmanned plane of all sizes is absolutely targeted on with the ability to fly what’s known as past visible line-of-sight [BVLOS].

Typically, the principles, notably for smaller business unmanned plane and actually for all un unmanned plane, both require a whole lot of techniques and mitigation or don’t enable flight of the plane past the line-of-sight of the pilot in any respect. This can be a actual bottleneck within the growth of the business and corporations like ours.

The FAA and lots of business producers and builders are engaged on overcoming this to have security techniques that assist you to fly past visible line-of-sight. Unmanned plane are required to stay nicely away from different plane always.

Despite the fact that there’s not a pilot on board you may have to have the ability to use sensors to detect different plane and stay nicely clear. That is usually known as detect-and-avoid. So, DAA techniques are the varieties of techniques that assist you to do that.

You might be notably frightened about detecting what are known as non-cooperative plane. These are plane that are typically smaller and they don’t have a transponder.

There’s a sure variety of plane within the US always and worldwide that aren’t required to hold a transponder and will not. So, it’s essential that your unmanned plane use sensors to keep away from these.

As well as, onboard detect-and-avoid means that you can make very long-range flights versus being restricted to a specific space the place you may need a ground-based sensor, for instance.

So, there’s various kinds of sensors and completely different operations these techniques as a result of they’re security important should be reliable and nicely examined. They’re actually important not solely to security however to the development of the entire business proper now

So, how can we use sensors? Specifically, those that I’m going to speak about immediately are direct integration of radar techniques right into a detect-and-avoid system. We use them to detect non-cooperative plane.

Our system relies on software program that calculates trajectories the tracks of plane after which detects a possible battle utilizing the sensor information and helps you keep away from that.

It is vital that these sensors present adequate warning to have the ability to calculate and perform the avoidance maneuver. So, after we consider sensors, that’s actually, actually important.

These are some images from a few of the developmental work that went into this expertise, notably a few of the working testing at NASA.

So, typical DAA system elements embody sensors so a radar often both onboard or ground-based. Generally they embody an EO/IR system. So, cameras and acoustic techniques are typically used – particularly to direct different sensors to an space that must be carefully noticed as a result of there is likely to be air site visitors coming in. Then different sensors like lidars often are used.

These techniques often contain a show and so human elements turn out to be essential in the way you talk data to the distant pilot.

Autonomous processes are additionally rising as essential. That is an space that we do a whole lot of work in and our system supplies an autonomous voting avoidance course of.

I’ll present you some screenshots that offers you a bit of little bit of an thought of how that works, however that includes algorithms and, more and more, AI and machine studying that will help you with that course of.

Then you’ll have entry to different non-sensor information sources, like climate information, which are being sensed elsewhere by federal businesses, for instance. To provide you data that’s additionally essential to the protection of your flight

So it is a little bit of data on our system I gained’t cowl it in nice depth right here, however I’ll simply point out that it does use this data to detect, monitor and keep away from conflicts with different plane. [FlightHorizon] supplies a 2D or a 3D show of the airspace and the air site visitors, and it fuses information from a number of sensors.

That’s essential as a result of you may have your personal plane within the air you’ll have quite a lot of different plane that you simply’re detecting perhaps in a few alternative ways. So with the ability to deconflict that in your show and your airspace mannequin so you possibly can perceive what’s the place and what’s approaching may be very, essential.

Right here’s a diagram of how this works. The essential merchandise for this speak is, in fact, the sensor within the center right here. That is the radar.

On the left-hand aspect you may have your unmanned plane. On the correct you may have an plane which may be getting into your airspace – a manned plane.

You’ll detect that with one in every of these sensors so a radar for instance if it does have a transponder you may detect it that method. All that data goes into the orange field within the middle and is used to create a mannequin of the air site visitors, so you understand what’s happening and might preserve situational consciousness. Then obtain particular instructions if you might want to carry out an avoidance maneuver.

Right here’s an image [below] that will help you perceive what the system is doing a bit of bit. So, on this case, within the center right here this white plane you may have your personal ship – your personal unmanned plane. On the right-hand aspect within the middle right here you’ll see there’s a small detected blue plane. That’s an plane that’s coming into your airspace and is presenting a possible battle.

The software program has used the sensors to detect that, calculate the battle, calculate an avoidance maneuver, after which it’s telling you to keep away from that. As you possibly can see, these sensors are completely important to the software program with the ability to carry out this perform and assist you to have a secure flight and deconflict from different air site visitors.

Now we have three variations of this. If you happen to’re on this, you possibly can attain me out to me afterwards.

Now we have a ground-based model known as FlightHorizon COMMANDER. That’s supposed for airspace administration. Now we have our FlightHorizon PRO model, which might run on a laptop computer or a pill for area use on the bottom. And, then now we have the FlightHorizon PILOT model, which is our onboard model.

You’ll be able to see an image of it right here flying with a radar beneath on a small hexacopter that’s getting used for some testing.

So, what are some issues within the use and collection of these sensors?

The very first thing, clearly, is these sensors have to have the ability to detect small, manned plane. That’s many of the site visitors that you simply’re frightened about once you’re flying an unmanned plane. A lot of the bigger plane can have a transponder notably as you might be flying at larger altitudes.

In case you have a bigger unmanned plane, you’ll be capable to probably make the most of air site visitors management, however in areas the place you can not do this, it’s completely important that you’ve got sensors to have the ability to present detection of the air site visitors.

It’s acquired to have adequate vary that it’s detecting the plane that you might want to keep away from far sufficient out which you could carry out and maneuver the swap, as we name it. It’s a essential issue of the sensor.

That is the scale weight and energy necessities, in order that it may well match on the plane or in any other case be positioned the place you want it to be positioned simply. It wants to have the ability to filter out litter so it’s detecting plane and might differentiate non-aircraft targets. That is extraordinarily essential. We spend a whole lot of time being positive that we are able to do this with the sensors that we use. Then working circumstances are essential.

You’ll see a few of the photos I’m going to. present you from a few of the testing and operations that we do are very in very chilly environments. So, [operating conditions are] essential. Climate, so primary suitability problems with the sensor and temperature and moisture different issues like that.

Unit worth versus mission worth. We’re very conscious of this. You might have to have the ability to use sensors which are appropriate for the worth of the varieties of business or different varieties of operations you’re finishing up.

We’re at all times engaged on affordability and making an attempt to develop techniques which are appropriate for the actual operation.

Then the combination path. So, how the software program talks to the sensor and the sensor talks to the software program is essential in our course of.

Once we take a look at sensors we’re taking a look at two issues. We’re trying on the primary sensor efficiency. Does it have the vary? Does it have the decision to have the ability to carry out the perform that we want it to carry out? Then we’ll use it in particular encounter testing within the area the place we can have a number of both unmanned or manned plane which are encountering the unmanned plane with the intention to take a look at and show that the system is ready to do what it must do.

We’ll take a look at sensors based mostly on both ground-based or on-board. Relying on what we’re doing, the radar will want to have the ability to filter out litter. That is actually a software program perform. Then reject false tracks that’s essential.

Once we do that testing, we’re actually establishing that baseline efficiency to have the ability to do that.

These are some images from some precise latest flight testing that now we have executed with quite a lot of sensors. I’m going to flip to the following slide right here the place we’ve acquired some labels.

This was a undertaking that was carried out with assist from the FAA and was executed with College of Alaska Fairbanks and the Alaska Heart for Unmanned Plane Techniques Integration [ACUASI].

This was a undertaking you possibly can examine it on our weblog by which we’re testing quite a lot of sensors. We’ve acquired the small radar that I confirmed in some prior slides right here. That is an EchoGuard radar from Echodyne. Now we have a GA-9120 which is a bigger longer-range radar which we’re additionally testing.

We’re capturing information and doing a whole lot of observations with these radars going into the software program.

I’ll present you one other couple of tasks we’ve executed right here.

That is one other image of the radar and the detect-and-avoid system flying onboard so you may have a single board laptop right here that has our software program working. It’s accepting information from the radar. It’s additionally acquired a transponder receiver. It has direct connection to the telemetry together with the GPS and different data from the plane.

The IMU, so the inertial measurement unit that’s built-in into the radar, for instance, is straight feeding the software program so it is aware of the place the radar is pointing which is essential once you’re flying round. We’re very enthusiastic about this technique.

Sometimes, these are the varieties of plane that we’re flying towards and testing towards to ensure that we are able to detect them. Small GA plane, like small helicopters which are usually used within the area at these altitudes.

This can be a image from a set of flight checks that we did with Oklahoma State College and the Unmanned Techniques Analysis Institute there. That is very fascinating.

We have been in a position to fly these two small drones shut to one another with the intention to do some very fascinating testing. You’ll be able to see some screenshots right here of the radar and different techniques monitoring each ownship and the intruder plane, as we name it (the opposite plane) with the system offering some particular maneuvers that should be carried out to carry out the avoidance.

This can be a very fascinating undertaking and we’re doing ongoing work with OSU and others.

This this was some work to check the vary of what’s known as the GA-9120 radar, which is bigger radar right here. This can be a radar that’s good for small air parks for instance. It’s transportable. You’ll be able to put it in that field and we take it the place we want it.

I’ll simply level out a pair issues on this image [below]. That is much like the techniques I’ve proven within the prior photos. Now we have right here a medical provide supply drone from Oklahoma State College that was utilized in some testing. We did some monitoring with that plane with our system. We’re enthusiastic about these sorts of tasks.

Our system is absolutely designed to permit these long-range flights and that’s actually the place the business is headed. So, getting a chance to work with these actually sensible, emergent plane is essential to us.

Simply one other slide right here. There’s some fascinating developments and sensors which have a big effect in unmanned plane and notably in detect-and-avoid which is absolutely on the cusp of the business proper now.

I at the moment serve on the FAA’s Aviation Rulemaking Committee, which is writing guidelines for past visible line-of-sight drones within the US. There’s motion proper now within the rules within the US which may be very thrilling. We’re very comfortable to have the ability to contribute to that effort.

There are rising developments with new radars smaller, lighter with longer vary detection is at all times essential. We watch that carefully. Sensors, in our case, are used as a part of a multi-sensor and multi-layered security system.

There’s a specific amount of procedural security after which you may have strategic security – the place you’re going to fly, once you’re going to fly, and coordinating these efforts. Then in the end the sensors are used for tactical security, to be able to detect plane that in any other case you won’t be able to know are there.

Higher algorithms are rising for trajectory prediction. Notably machine studying is rising as a approach to filter and do goal classification so you possibly can higher establish whether or not you’re taking a look at a hen or whether or not you’re taking a look at one thing that you simply shouldn’t classify as an plane and don’t want to fret about essentially. That could be a nice space of growth.

Then millimeter wave radar on a chip is one thing that we’re watching carefully. There are rising smaller radars which are based mostly on some 5G applied sciences which have overlap with different rising millimeter applied sciences. We expect that that’ll be very helpful for the business.

Then, as I discussed, there are new technical requirements. It was talked about in my bio that I serve on a number of technical normal writing teams. Then there are FAA rules which are actually pushing the business ahead.

There’s my contact data. Thanks very a lot once more for the chance to talk.

We’re comfortable to take any questions and to hear from you to reply extra questions on something I’ve introduced. Thanks.
