    • VO2 MARS RADIO SCIENCE SUBSYSTEM RESAMPLED LOS GRAVITY V1.0

    Metadata Updated: August 22, 2025

    Line of sight (LOS) gravity data were obtained as part of the Radio Science Experiment by tracking 79 orbits of the Viking Orbiter 2. The data set consists of a table with the following columns: spacecraft latitude, longitude (degrees), accelerations, and altitude (km). The acceleration data were determined from differentiation of raw Doppler residuals and are expressed as units of mm/s2. To obtain LOS gravity in milligals, accelerations need to be multiplied by 100. An acceleration of 1.20 mm/s2, therefore, corresponds to 120 mgal, a large gravity anomaly.
