MESSENGER RSS Raw Data Bundle
This bundle contains raw radio data that can be used to determine the position and velocity of the MESSENGER spacecraft during flybys of Venus and Mercury and during orbital operations around Mercury. The bundle also contains measurements of occultation times and calibrations for the effects of Earth's ionosphere and troposphere, meteorological conditions at stations of the NASA Deep Space Network, thruster activity, and changes in spacecraft antenna selection. The data were used to determine the gravity field and shape of Mercury and to improve solar system ephemerides. The bundle is a migration of data from the original PDS3 archive with minor improvements and corrections. -
bundle:
MESSENGER gravity and topography spherical harmonics model bundle
The bundle contains derived models of Mercury gravity and topography from radio science tracking and from the MLA instrument on MESSENGER. There are three product types: the Occultation Summary (OCC), the Spherical Harmonics ASCII Data Records (SHADR), and the Spherical Harmonics Binary Data Records (SHBDR).
