Galileo is Europe’s own global navigation satellite system, providing a highly accurate, guaranteed global positioning service under civilian control

Elecnor Deimos has been present in the Galileo project since the company was established, having participated in the Pre-development phase, the Phase C0 and Phase C/D, in all segments. In the ground segment, Elecnor Deimos has provided support to ESA for the integrity concept definition and has developed three Ground Mission Segment (GMS) main facilities as prime contractor:

  • Galileo Raw Data Generator (RDG): an environment simulator that generates very accurately simulated synthetic data allowing tests of Algorithms prototypes, Operational elements and the Galileo Mission System.
  • Message Generation Facility (MGF): one of the most critical elements of the Galileo GMS, responsible for the generation of the navigation message to be up-linked to the Galileo constellation. The MGF operational strict real-time embedded software has been developed under the strict Galileo Software Standard. The software executes on three time-synchronized processing boards and on a partitioned Operating System, which allows isolating the most critical functionalities from the rest. It is working operationally at full customer satisfaction.
  • Mission Support Facility (MSF): for system monitoring and calibration. It computes off-line Orbit Determination and Time Synchronisation (OD&TS), providing estimated orbits and the offset between the satellite and station clocks with respect to the Galileo System Time, used to calibrate the operational OD&TS of the GMS, the Orbit & Synchronisation Processing Facility (OSPF). It also performs the Satellite Model Calibration, Historical Signal-In-Space Calibration and Pre-processing Residual Error Calibrations.

Development of three Galileo Ground Mission Segment main facilities as prime contractor, participating also in the space and user segments

In the space segment, Elecnor Deimos provides engineering support to ESA with on-site collocated staff. For the user segment, Deimos has participated in the Second Source Test User Segment (TUS), as a subcontractor of Septentrio, developing the Off-line TUR Analysis Tool. In addition, Deimos has developed its own Galileo receiver prototype.

Elecnor Deimos has a leading role in promoting applications taking advantage of the unique capabilities of Galileo, such as the accurate E5 signals, space applications or reflectometry, having carried out several award winning FP7 and H2020 projects.
