Abstract

This paper presents the ground and flight test results of an above ground level (AGL) sensing device using pulsed laser ranging. The sensor was developed to integrate with automated flight controls used in manned and unmanned aircraft for precision landings. Using highly accurate, real-time distance measurements AGL readings can be used to feed flight controls to minimizing landing loads and approach speeds. The sensor uses a pulsed laser and receiver to measure the time of flight between the laser fire and return signal from the ground. This line of sight range in conjunction with the air vehicle attitude readings provide a precise (6 inches resolution) above ground level measurement fully compensated for slant range.
