Abstract
A wireless intrasatellite communication system is disclosed. Satellite telemetry signals are multiplexed, converted into a digital data stream, and processed by an ASIC to form a multiplexed telemetry data stream. An infrared transceiver transmits the multiplexed telemetry data stream along an optical path to a designated interface that is associated with a remote command and telemetry unit. Telemetry signals are aggregated within a plurality of remote command and telemetry units and transmitted to a central command and telemetry unit via a high-speed digital bus. Command data issued from the central command and telemetry unit is distributed to a designated remote command and telemetry unit, and is routed to the appropriate user unit via the optical path. The user unit processes the command data and generates a responsive command signal output.
