Satellite control experiments via the CS
Abstract
TT&C satellite control experiments conducted aboard the CS communications satellite, including monitoring of housekeeping data and commanding the execution of mission tasks, are described for the cases of attitude and orbit determination, tracking, and despun antenna pointing. Ranging experiments conducted via TT&C, one-hop, and two-hop communications channels are described. Orbit determination tests were carried out using one station's ranging data and K-band tracking angle data, demonstrating accuracies comparable to those of a two-station system. Altitude prediction and determination tests have shown an error of 0.01 deg for 10-day period predictions, which is sufficient for planning attitude maneuvers.
