 Hi, my name is Chris Gates with NexNav. In an increasingly urbanized world, 2D location technologies are no longer capable of delivering compelling user experiences. Finding people places or assets and tall buildings are providing actionable location for critical safety services. I'm here today to talk a little bit about how NexNav and ST are enabling powerful new 3D location capabilities and elevating the blue dot into the complex world we live in. By combining NexNav's network and software with ST pressure sensors, floor level of 3-meter accuracy is achievable. And this accuracy is crucial because most people experience altitude four by four. Whether identifying the altitude of a 911 caller seeking critical aid, providing enhanced situational awareness to first responders, delivering terrific AR experiences or improving user experiences in retail, or even enabling better ride-sharing outcomes, Z-Axis provides a critical element to a complete location solution. How do we do this? Devices from mobile phones to smartwatches contain high-quality pressure sensors today. We combine the measurements from these pressure sensors with data from our dedicated wide area altitude network through our cloud services platform and enable these devices to get the highest accuracy altitude available today. And importantly, this service is available across entire metro areas. It's not restricted to specific buildings. Our service is available nationwide in the US with over 105 major metros live by April 2021, including all 50 CMAs required by the FCC for 911 Z-Axis service. Here are a couple of ST sensors found in mobile devices that help make this possible. And I would like to share a short video with you showing how all this comes together to make wide area 3D location a reality. Hi, this is Dan with NextNav. And today I'm gonna show you our Pinnacle service in action using the NextNav Z-Axis Evaluation app. This will show two different measurements, height above ellipsoid, which is a smooth surface representing the highs and lows of the terrain as it's not flat. And the HAT, which is height above terrain, consider that the ground floor. So those are the two values that are evaluation Apple measure, and let's see how that works in action. As I'm recording this, I'll actually show my screen so you'll see this side by side. So as we start walking up the ground floor, the second floor, you will notice both the HAT and the H-A-E moving out as we're walking up the staircase. Today we're providing two values and the H-A-T and the H-A-E. Longer term, we'll actually have a solution. So they'll show you that what floor we're actually on. That's a harder problem to solve and we'll have a few different versions coming out over the next few months, so stay tuned for that. And as you can see, as we move up to the third floor, my H-A-T is about seven, 7.6. It'll take you just a second to finalize at just about eight meters above the ground. Now let's start heading back down. You'll notice that both my H-A-T and the H-A-E are moving down, indicating that we're going down. And coming back down to the ground floor, you will see that both measurements are coming down in line with where we are. So hopefully that gets you a good idea of Z-Axis in action with our PENICLE service. We think this has great application from everything from public safety to consumer applications to new mobile games that can be created using PENICLE service. Thank you very much.
