MGS Science Sampler: RSS Data

This volume contains two spherical harmonic gravity models of Mars based on data from Mariner 9 and Viking. These models can be considered the baseline gravity models at the beginning of the MGS mission; they will be updated with data from the MGS Radio Science Subsystem (RSS) during the mapping phase of the mission. These data products do not contain any MGS data. The files are ASCII tables with detached PDS labels. Radio Science data are described in the VOLINFO file in the DOCUMENT directory.

GGM50A01.SHA Gravity Model produced by Goddard Space Flight Center [PDS Label GGM50A01.LBL]

JGM50C01.SHA Gravity Model produced by Jet Propulsion Laboratory [PDS Label JGM50C01.LBL]
