Planetary Dynamics I: Shape, Gravity, Orbit, Tides, and Rotation from Observations and Models

Shape, gravity field, orbit, tidal deformation, and rotation state are fundamental geodetic parameters of any planet, satellite, asteroid, or comet. Measurements of these parameters are prerequisites for e.g. spacecraft navigation and mapping from orbit, but also for modelling of the interior and evolution of the object. This session welcomes contributions from all aspects of planetary geodesy, including the relevant theories, observations and models.
