3 • True Terrain Following Kit
The True Terrain Following (TTF) enables the drone (UAV) to accurately follow the terrain
during the flight, based on data received from the laser or radar altimeter. True Terrain
Following enables the drone to fly at low and constant AGL altitudes (up to 1 meter) without a
need to import precise Digital Elevation Model (DEM) height-map into UgCS.
