Telemetry Decoder Shell

The Telemetry Decoder Shell package is a commercial off-the-shelf (COTS) software component which implements the ground based parts of the TM Space Data Link Protocol and supports the related standards.

It gives access through an API (Application Programming Interface) to the telemetry facilities using calls in ANSI-C. It is highly portable and easy to incorporate into different software systems, such as simulators, ground control systems and ground testing systems (EGSE).

TM Decoder Shell ground system application

The Telemetry Decoder Shell accepts telemetry transfer frames. The frames are the Version-1 frames defined for the TM Space Data Link Protocol. (Our AOS Decoder Shell accepts the Version-2 frames defined for the AOS Space Data Link Protocol of CCSDS Advanced Orbiting Systems.)

The Telemetry Decoder Shell delivers packets. It also delivers data from the Frame Secondary Header (FSH) and the Operational Control Field (OCF). The Operational Control Field can be used to carry CLCWs (Communications Link Control Words) for telecommand (COP-1 in the TC Space Data Link Protocol).

There is more about the facilities and interfaces of the Telemetry Decoder Shell in the detailed description.
