Abstract
The Ground/Orbiter Lasercomm Demonstration conducted between the Japanese Engineering Test Satellite (ETS-VI) and the ground station at JPL’s Table Mountain Facility, Wrightwood, California, was the first ground-to-space two-way optical communications experiment. Experiment objectives included validating the performance predictions of the optical link. Atmospheric attenuation and seeing measurements were made during the experiment, and data were analyzed. Downlink telemetry data recovered over the course of the experiment provided information on in-orbit performance of the ETS-VI’s laser communications equipment. Bit error rates as low as 10^-4 were measured on the uplink and 10^-5 on the downlink. Measured signal powers agreed well with theoretical predictions.
