TM/TC EGSE
Status:
Available
The EGSE is ideally suited for the verification of FPGA designs and validation of ASIC devices, as well as during the integration of complete TM/TC boards or communication subsystems.
Overview
The CCSDS / ECSS Telemetry and Telecommand EGSE (Electrical Ground Support Equipment) provides the necessary means for communicating with the on-board space segment. It has been designed to support satellite integration and test activities, on-board space segment development, ground segment applications, etc.
The EGSE communicates directly with the on-board telemetry encoder and telecommand decoder devices, TM/TC boards and units, bypassing the transponder. The EGSE is ideally suited for the verification of FPGA designs and validation of ASIC devices, as well as during integration of complete TM/TC boards or communication subsystems.
The TM/TC EGSE comprises two parts: a generic hardware implementing the lower CCSDS / ECSS protocol levels; and advanced software implementing the higher CCSDS / ECSS protocol levels. The TM/TC EGSE is fully compliant with the latest CCSDS recommendations and ECSS standards.

Detailed features
The TM/TC EGSE hardware establishes the link between the on-board flight segment and the ground segment software. The EGSE features standardized RS422 interfaces supporting up to 10 MBPS transfers on the downlink and up to 1 MBPS on the uplink. The EGSE hardware communicates with the ground segment software through a 10/100/1000 Mbit/s Ethernet interfaces via TCP/IP. The TM/TC EGSE hardware is based on our GRTMRX and GRTCTX IP cores.
