The Magsat telecommunications system
Abstract
The Magsat telecommunications system is based on the Small Astronomy Satellite (SAS-3) with newly designed telemetry modulation control and recorder interface electronics. A microprocessor-based design for the Magsat command subsystem offers expanded capabilities and increased flexibility in real-time and delayed commanding operations. The major telecommunication hardware functions are presented along with the primary signal flow paths. The standard transponder and associated diplexers, couplers, and antennas are shared by the command and telemetry subsystems. The recorder-transponder interface in the telemetry subsystem provides signal cross-strapping and mode selection for the transmission of data from the tape recorders through the transmitters.
