Context

CNES is in charge of LEOP GALILEO satellites for IOV (In Orbit validation) and FOC (Full Operational Capability) phases. Industrial organization: CS GROUP with ALTRAN as subcontractor Satellites: ADS and OHB Also RAO in 2015 for the WP6 and GSOP phases Environment: ESOC (MOIS, SCOS2000)

CS Group responsabilities for GALILEO On-board Operation Support are as follows:

Ground assets preparation, support for LEOP operations of the constellation’s satellites

Main Picture

The features are as follows:

SOE Position (Spacecraft Operations Engineer) for DHS, TTC and AOCS subsystems
Training on ESOC and CNES ground segment
Production and validation of Flight Operations and associated files (monitoring, displays, mimics, …)
Support for following up the on-board team
Participation to the simulation exercices (SVT, QO and LEOP)
Participation in project reviews
Participation in LEOP

Project implementation

The project objectives are as follows:

Support to the CNES OP sub-directorate for the preparation and monitoring of leop operations of satellites of the Galileo Constellation

The processes for carrying out the project are:

Support

Technical characteristics

The solution key points are as follows:

European context: CNES / ESOC / Astrium / OHB
