Providing specialist technical support to ESA navigation projects Galileo and EGNOS


The section is responsible for the support to ESA navigation projects (e.g. Galileo, EGNOS) on the design, simulation, development and testing of radio navigation equipment and techniques with particular focus on GNSS receivers for ground and space applications. The section also supports Galileo tests-bed activities in laboratory, and on open-field using adapted vehicles, for both OS and PRS services.

  • Performing Galileo static and dynamic data acquisition campaigns with real SIS, to be used for analysis such as In Orbit Validation (IOV), In Orbit Testing (IOT) and early-service validation.
  • Setting up, operating and maintaining in-lab navigation test-beds in order to support verification and validation campaigns, as well as monitoring of key performance indicators (UERE, PVT accuracy and availability, timing accuracy, etc.).
  • Procurement, testing, operating and maintenance of GNSS FOC Test User Receivers (TURs).
  • Supporting SIS design, analysis and validation for current and future navigation systems.
  • Monitoring of contracts with industry for studies on radio navigation concepts and for the development of radio navigation professional equipment.
  • Supporting the continuous monitoring of Galileo Early Services.
  • Investigating Galileo PRS evolution design in GMS, including system compatibility.
  • Supporting Galileo IOT campaigns, including sensor station characterization, orbit estimation performance and on-board clock characterization (TGVF).
  • Co-chairing Galileo engineering board and participating on the technical discussions on the Galileo system baseline.
