Current Locations of Soar Truckee Gliders
Gliders equiped with SPOT satellite tracking devices uplink position telemetry every 10 minutes to Globalstar low earth orbit satellites. SPOT sends only lattitude and longitude data. GPS positions are then downlinked to SPOT servers and are superimposed on Google maps. SPOT is capable of displaying the track of one glider on a map at a time. The ability to display multiple tacks on a single map like a radar screen is currently in development.
