Control and telemetry signal communication system for geostationary satellites

摘要

A geosynchronous satellite control and telemetry communication system has branch modules distributed throughout the satellite which serially interface clusters of control and/or analog nodes to the central command and data handling processor. Each branch module is connected to the central command and data handling processor by serial data channels. The branch modules are physically located close to the control/telemetry nodes for which they serve as interfaces to the central command and data handling processor and where appropriate are integrated into the satellite subsystems themselves.
