Abstract:

A Hughes-developed laser communication terminal was delivered for Air Force Testing that is related to aircraft applications. The terminals employ laser diode transmitters, PIN diode receivers, and provide automatic tracking with a gimbal-mounted video camera and off-gimbal video tracker. The terminals are capable of 20 Kbps full duplex operation over 8-10 miles at sea level. Video tracking offers a legitimate alternative to quadrant tracking. The terminals were modified to provide performance monitors for transmitted signal, received signal, AGC voltage, tracking error, tracker status, and angular position. An automatic acquisition capability with spiral scans was implemented and performed well.
