2001 MARS ODYSSEY RADIO SCIENCE RAW DATA SET - V1.0

2004-02-27 RS:simpson added2004-03-01 RS:simpson revisedThis data set contains archival raw, partially processed, and ancillary/supporting radio science data acquired during the 2001 Mars Odyssey (ODY) mission. The radio observations were carried out using the ODY 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 ODY operations procedures and to be used in reconstructing the spacecraft orbit, generating high-resolution gravity field models of Mars, and determining the nature of the near-Sun solar plasma. Of most interest are likely to be the Orbit Data Files in the ODF directory and the ionospheric and tropospheric media calibration files in the ION and TRO directories, respectively. The first ODF in the data set begins on 2002-01-06, which was actually in the late stages of the Aerobraking Phase and just before periapsis was lowered for about 2 weeks to about 200 km; the Mapping altitude was about 400 km. Data were delivered to PDS in approximately chronological order at the rate of 1-3 CD-WO volumes per month, of which about 0.01 GB/month were ODF's. By volume, the largest data type was either the Archival Tracking Data File (TDF; until early 2003) or the Tracking and Navigation File (TNF; beginning early 2003), both of which served as parents of the ODF.
