An aircraft mounted laser communications system is being developed for an air to air communication experiment to be performed over a range of 50 to 500 kilometers at altitudes up to 40,000 feet. The purpose of the experiment is to demonstrate and characterize communication between two aircraft at various ranges, altitudes and atmospheric conditions. Communication data rates are up to 1 GBPS using four on-off keyed 810 nm diode lasers multiplexed into two circularly polarized transmitting apertures. The communication receiver uses a 134 mm diameter Matsutov telescope with APD's for the detectors. Two separate beacon lasers at 852 nm provide sources for tracking. Two T-39 aircraft each will be equipped with a laser communication system and experimental data collection equipment.
