Telecommand Unit Testing; Cop" Software Package - Safran CORTEX CRT Quantum User Manual

Telecommand Unit Testing

3.5.8.
When the TCU is programmed in TC Simulation mode, TC requests and TC instructions received on the
Telecommand port are normally processed and acknowledged but the TC tones (pure tone or FSK or PSK
signal) are not transmitted to the IF Modulator.

"COP" Software Package

3.5.9.
The optional « COP » software package communicates with the Signal Processing Software package and
remote SCC Clients via Ethernet, under TCP-IP protocol. Five types of data transfer are to be considered:

« COP »» Monitoring:
The Monitoring port (COP-MON) is used to remotely acquire current the « COP » status. The «
COP » can be monitored simultaneously by up to four TCP-IP clients.

« COP » Control:
The Control port (COP-CTRL) is used to remotely program the « COP » functional parameters.
The « COP » can be controlled by only one TCP-IP client at a time.

The Telecommand port (COP-TC) is used to receive TC Segment Frames from remote
Telecommand Clients and to return associated acknowledgement or information messages.

Satellite Telecommand Data (CLTU) to the Signal Processing Software:
Satellite telecommands are transmitted, at CLTU level, to the Telecommand port (TC) on the
Signal Processing Software. The Signal Processing Software provides all functionalities
associated to the physical layer.

Telemetry Data from the Signal Processing Software:
Telemetry data are provided to the « COP » via the Telemetry port (TM) on the Signal
Processing Software. These data are used to check the CLCW status and satellite ID.
