ESOC’s Navigation Support Office generated the first Precise Orbit Determination for FOC Galileo Satellite – GALSAT 202

Thursday, March 19th, 2015

On Thursday, 19 March 2015, the Navigation Support Office located at the ESA’s European Space Operations Centre in Darmstadt (Germany), performed the first Precise Orbit Determination (POD) of the second FOC Galileo Satellite – GALSAT 202. The POD for Galileo 202 was based on the processing of signals in the L-Band, transmitted by the Galileo satellite and received by the Navigation Support Office’s global distributed GNSS sensor station network in conjunction with data from the International GNSS Service (IGS) network of sensor stations, used in the context of the MGEX experiment.

ESA’s Navigation Support Office supports the In-Orbit Test of the 1st Galileo FOC satellite

December 2014/January 2015 ESA’s Navigation Support Office supports the In-Orbit Test (IOT) of the 1st Galileo Full Operational Capability (FOC) satellite. This IOT is of particular importance to the Galileo project since it for the first time allows the analysis and evaluation of Galileo FOC satellite performance and in this case for a satellite in a non-nominal, elliptical orbit.

ESA’s Navigation Support Office performed the very first Precise Orbit Determination for the 1st Galileo FOC satellite (GSAT201)

Tuesday, March 17th, 2015

GSAT201 is the first FOC satellite and one of the two Galileo satellites delivered into a wrong orbit by VS09 Soyuz-Fregat in August. After a successful recovery, GSAT201 transmitted its first signal on Saturday 29 November 2014. Although, the target orbit is not nominal, ESA’s Navigation Support Office performed the very first POD on 3rd December with promising accuracy.
