The Galileo for Science Project (G4S_2.0) is an ongoing project funded by the Italian Space Agency that has several goals in field of Fundamental Physics exploiting Galileo-FOC Constellation and, particular, GSAT0201 (E18) and GSAT0202 (E14), two satellite elliptical orbit. By accuracy atomic clocks on board satellites, particular clock-bias estimated process data reduction tracking observations during a Precise Orbit Determination (POD), it allows one hand to measure gravitational redshift, constraining Local Position Invariance (LPI) other hand, place constraints possible presence dark matter our galaxy form Domain Walls. A fundamental point obtaining suitable orbit solution performing accurate POD. In this context, activities carried out with Bernese code will be presented.
