The MRO Gravity/Radio Science (GRS) Spherical Harmonics Gravity Binary Data Record (SHBDR) product is intended to be general and may contain coefficients for spherical harmonic expansions of gravity, topography, magnetic, and other fields.

SHBDR files are created from radio tracking, vertical sounding, in situ, and/or other measurements at the institution conducting the scientific data analysis. Each model requires data with complete sampling (in terms of longitude and latitude coverage on the planet), so that SHBDR files will be issued infrequently and on schedules which cannot be predicted at this time.

In general, the SHBDR is recommended over the Spherical Harmonics Gravity ASCII Data Record (SHADR) when the data include error covariances because of the smaller data volume associated with binary formats.

There are four SHBDR products: GMM3_120_SHB.DAT, with corresponding label file; JGMRO_095A_SHB.DAT, with corresponding label file; JGMRO_110B_SHB.DAT, with corresponding label file; and JGMRO_120D_SHB.DAT, with corresponding label file.

In ODE, the SHBDR products have the following Product IDs (in the same order as listed above):

GMM-3

JGMRO_095A_SHB.DAT

MRO110B

JGMRO_120D_SHB
