Collaborative calibration of MEO GNSS signal biases based on LEO satellites GNSS-BICS

GNSSBICS is a feasibility study carried out in the frame of the ESA’s General Studies Programme (GSP)
by DEIMOS-Space, Deimos-Engenharia and ESA.
This activity investigated what G/S infrastructure would be necessary to develop a System, named as GNSS-BICS (GNSS Bias Calibration System), in charge of providing, under demand, the GNSS MEO S/C SISBAF (Signal-In-Space Biases Amongst Frequencies), from GNSS observations gathered by GNSS multi-frequency receivers on-board LEO satellites (potentially from different missions).

Weak GNSS Signal Navigation on the Moon

Global Navigation Satellite Systems (GNSS) are already used in space missions (e.g. GOCE, Swarm, Sentinel, and MetOp, among others), not only as a navigation sensor (either for autonomous orbit and attitude determination or for relative navigation) but also as a science instrument (e.g. for altimetry, global geodesy, Radio Occultation and GNSS Reflectometry applications). However, its use is usually limited to orbits or mission phases below the orbits of GNSS satellites, since GNSS satellite antennas transmit mainly in the Earth's direction.
