Martian gravity field long wavelength seasonal variations model from Mars Global Surveyor radio science measurements
Abstract
By using one-way and two-way Doppler X-band tracking data of Mars Global Surveyor (MGS) from March 1998 to December 2003, the determination of the time-varying zonal gravity coefficients J2 and J3 and of the second degree Love number (k2) has been undertake. The amplitudes of the temporal variations of J2, J3 and the k2 value may be compared to those of modelled signals derived from Mars GCMs (global circulation models) and to previously obtained solutions.
