Specification of the Galileo Control Centre


Composition of the Galileo Control Center

The Galileo Control Centre consists of three components:Building with at least 2800 m² and related infrastructure

Heating, Ventilation and Air Conditioning, Power Supply, Security Systems, Fire Protection, Electrical Systems, Telephone Connections, Voice Intercom, Video Distribution, Control Room Consoles, Furniture

Galileo Specific FacilitiesGCS and GMS facilities (e. g. PTF)

Skilled Personnel Operating the Galileo Facilities and the Control Centre Infrastructure

ManagersEngineersControllers (on shift)


A Galileo Control Center consists of 2 SegmentsGround Control Segment (GCS)

Satellite Platform, Payload and Constellation Control

Ground Mission Segment (GMS)Precise orbit determination and clock synchronization, integrity evaluation

The number of facilities and their interactions contributes to the complex Galileo System structureThe status of the various local and worldwide networks has to available at any timeFor security reasons transferred data will be encrypted on various levels GCS GMS
