• TT&C activities for METOP satellites in S-Band: These TT&C data sets will bearchived locally and sent to/fromEUMETSAT headquarters in Darmstadt viathe intersite network

• TT&C activities for NOAA satellites in S-Band: These TT&C data sets will bearchived locally and sent to/fromEUMETSAT headquarters in Darmstadt

• GDS Data acquisition from METOPsatellites in X-Band to be processed locallyby the FEP before to be sending toEUMETSAT headquarters

• GAC Data acquisition from NOAA satellitesin L-Band to be processed locally by theFEP before to be sending to EUMETSATheadquarters

• L-Band HRPT and VHF-band LRPT carriersmonitoring from METOP satellites

The main role of the PSF is to acquire signalsfrom polar orbiting satellites and to ensurethe control of such satellites. Two kind ofsatellites are considered:

• European METOP 1, 2 and 3 of EUMETSAT

• US NOAA N and N’ of NOAA

The PSF is composed of three earth stations:

One Reference User Station (RUS) locatedat EUMESAT headquarters in Darmstadt(Germany)This station will be used by operators asreference station and will provide L-bandHRPT and VHF-band LRPT carriersacquisition and transmission to a dedicatedFEP.

• A mission message processor in charge ofmessage coding and assembly

• A monitoring and control system tomanage the chain and the externalinterfaces

• A set of two shelters for field deployment

• A GALILEO system time receiver forfrequency and time synchronization
