Packet Telecommand and Telemetry Simulator

The Packet Telecommand and Telemetry Simulator is an interactive tool for demonstrating a spacecraft communications system based on the telecommand and telemetry standards. The interactions from a run are saved in report files and can be re-run to reproduce significant cases.

The simulator represents:

TC/TM simulator overview

The simulator is useful for investigating the function and operation of a packet telecommand and telemetry system, especially the COP-1 protocol for telecommand.  The user can:

(Note: The simulated packets are generated inside the simulator. They cannot be input from an external source.)

The simulator contains full implementations of the telecommand ground based (encoder) and on-board (decoder) elements, built from our TC Shells.  Similarly, the telemetry on-board (encoder) and ground-system (decoder) elements are built from our TM Shells.

The simulator is an executable program which runs on a PC under Windows 98/NT or later.

We have developed special versions of the simulator for use in studies of other protocols: for example, we replaced the COP-1 elements of the simulator with COP-P for a study of Proximity-1.  We use the regular version of the Packet Telecommand and Telemetry Simulator in-house, for testing each new release of our software products.

The use of the simulator can be arranged as an addition to licences for our Shell packages or in addition to other services.
