Telemetry Considerations for Large Space Vehicles

This paper discusses some of the problem areas and considerations unique to large space-vehicle telemetry. Some significant characteristics of specific telemetry multiplexing and modulation techniques are pointed out. The contributions to real-time data requirements such as vehicle prelaunch monitoring and checkout that can be made by telemetry techniques are described. Finally, some observations are made on the direction of future research and development (R & D) effort in the telemetry field.
