Galileo navigation program is in progress under the technical supervision of the European Space Agency (ESA). The preliminary activities related to GSTBV2 experimental satellite provide the first results and the implementation of the in orbit validation (IOV) phase are in progress. Atomic clocks represent critical equipment for the satellite navigation system and clocks development has been continuously...
Two hydrogen masers (HM, a primary and a backup) are used in the precise timing facility (PTF) to provide the physical realization of Galileo System Time (GST), insuring the extremely high short-term stability required for the navigation functions, in particular to perform a reliable satellite clock modeling. In order to allow a smooth switch-over between backup and primary HMs in case of failure...
Galileo program is approved by the European Commission and the European Space Agency (ESA). The activities related to GSTBV2 experimental satellite provide the first results and the implementation of the In Orbit Validation (IOV) phase are in progress. Atomic clocks represent critical equipment for the satellite navigation system and clocks development has been continuously supported by ESA. The Rubidium...
