Tidal deformation of planets and satellites

Gregor Steinbrügge, Technische Universität Berlin, Technische Universität Berlin, Jürgen Oberst
2018
At cross-over locations of the ground tracks, which canbe derived from the spacecraft trajectory, the tidal deformation can be retrieved by a differential height measurement.  ...  The measurement of h2 is further complicated by only small variations of the tidal potential and by Mercury's slow rotation rate.  ...  A portion of this work was carried out by the Jet Propulsion Laboratory, Califor-nia Institute of Technology, under a contract with NASA.  ...
