GRAIL MOON LGRS DERIVED GRAVITY SCIENCE DATA PRODUCTS V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: August 03, 2025 | Last Modified: 2025-07-17
This data set contains archival derived science data, acquired from the Lunar Gravity Ranging System (LGRS) on the two spacecraft comprising the Gravity Recovery and Interior Laboratory (GRAIL) mission. Measurements were made using the GRAIL spacecraft and Earth-based stations of the NASA Deep Space Network (DSN). The data set includes high-resolution spherical harmonic models of the Moon's gravity field, covariance matrices for some models, and maps for some models. It also contains a complete set of SPICE SPK Files ('kernel files'), which can be accessed using SPICE software. The SPK products in this data set differ from those archived by GRAIL navigation, as they were created by the GRAIL SDS and make use of the LGRS to provide a more refined solution of the spacecraft ephemerides than those provided by GRAIL navigation.
