A Matlab/Octave-suite of programs for simulating satellite orbits and retrieving gravity field information from satellite tracking data.

Visualisation of a simulated orbit

This suite is basically built for simulating satellite gravity field missions and their observables. The simulation itself is rather rudimentary, because it only deals with the spacecraft as a point mass. This means that one cannot simulate the spacecraft rigid body dynamics. Nevertheless, it is sufficient to analyse the behaviour of the orbit and to do some pre-mission analysis.
