MARS GLOBAL SURVEYOR RAW DATA SET - MAP V1.0

This data set contains archival raw, partially processed, and ancillary/supporting radio science data acquired during the Mapping (MAP) phase of the Mars Global Surveyor (MGS) mission. The radio observations were carried out using the MGS spacecraft and Earth-based receiving stations of the NASA Deep Space Network (DSN). The observations were designed to test the spacecraft radio system, the DSN ground system, and MGS operations procedures; to be used in generating high-resolution gravity field models of Mars; and for estimating density and structure of the Mars atmosphere. A small number of surface scattering experiments were also conducted. Of most interest are likely to be the Orbit Data File and Original Data Record files, in the ODF and ODR directories, respectively, which provided the raw input to gravity and atmospheric investigations. The MAP phase extended from March 1999 through January 2001. Data were organized in approximately chronological order and delivered on a set of 184 CD volumes at the rate of 2-3 CD's per week. Typical volume of a one-day ODF was 300-400 kB. Typical volume of an ODR was 5-10 MB, and there were typically 8-16 ODR's per day depending on DSN schedules and observing geometry.
