Using computation based on infinitesimal rotations, we construct a linearized analytical formulation of the Doppler signal between a lander on Mars' surface and an orbiter with a precessing orbit around Mars. This simulates the Netlander Ionosphere and Geodesy Experiment (NEIGE) observable. This formulation allows us to understand how the geophysical information (nutation, polar motion) appear in the signal. We study different lander locations and changes in the orbital parameters of the orbiter performing the data relay, in order to see how the Doppler signature of the geophysical phenomena under study can be maximized without any lost in the information content. We also qualitatively compare the relative amplitudes and signatures of the parameters influencing the observable.
