The Laser Altimeter – Lower UAV Print
The laser altimeter serves two purposes on the lower aircraft. Firstly, it measures the distance between the aircraft and the ocean surface as input to the low altitude flight control algorithm (see Figure 2). Secondly, once the aircraft motion is removed from these measurements using the onboard DGPS/INS unit, we obtain the surface-wave profile along the aircraft track The laser altimeter serves two purposes on the lower aircraft.
