![]() They perform checkups on satellites twice a day to monitor and predict the satellites functionality. The job of these stations is to monitor the health of the satellites. and it has six monitor stations around the world. It is made up of the master ground station in Colorado Springs, Colorado, U.S.A. I’m confident you’re all familiar with GPS because you use it on your phones, and your cars, your watches, and of course in our aircraft. During low visibility and night flights they used bonfires to light up the way, and they still do that for air strips in Alaska and around the backcountry.Īviation has come so far in the last 100+ years, that now we rely heavily on GPS for navigation. These crazy pioneer pilots flew 200 to 400 feet AGL using only a magnetic compass, roads, railways for navigation. Before there was GPS, the first pilots flew this way. Anyone that has made a paper Nav Log understands how tedious and labor-intensive it can be. However, I still have an appreciation for the navigation that the first aviators and aviatrixes used, and that’s ‘pilotage’ and ‘dead reckoning’. GPS provides continuous accurate three-dimensional coverage anywhere on or near the Earth’s surface. So, I love GPS I learned to fly on all glass cockpit myself. GPA & NavigationĪll right, now it is time to talk about GPS and navigation. ![]() We’re also going to talk about RAIM and WAAS, we’ll get into that in a bit. ![]() There’s three segments in a GPS system to know about, the control segment (which is the ground station), you have the space segment (which is the satellite system), and then the user segment (which is your Garmin or the equipment device). Understanding how GPS functions as a whole, will help you understand how your Garmin works. Today, I’m going talk to you about how GPS operates it’s different systems and its potentials for error. My name is Beth Brown and I’m a Check Instructor here at AeroGuard Deer Valley. Hi, thanks for watching this training video presented by AeroGuard Flight Training Center.
