Abstract

The applicability of a fiber-optic telemetry and command (T&C) system for a large communications satellite system is analyzed. This system is characterized by low bit rates (below 1 Mbit/s) and relatively short transmission distances (below 20 meters). Various LAN (local area network) architectures and required components are examined for this application. The most suitable system is found to be a transmissive star network using LEDs, PIN detectors, and large size multi-mode optical fibers. This system is competitive in power and mass for certain T&C applications with conventional wire systems but offer a much higher immunity to electromagnetic interference. A new optical rotary joint, required for spin-stabilized satellite applications, is discussed.
