VEX-X-VRA-1-2-3-NMP-0048

Data Set Overview The Venus Express (VEX) Radio Science (VeRa) Data Archive is a timeordered collection of raw and partially processed data collected during the Venus Express Mission. This is a Solar Conjunction measurement covering the time 20061019T21:00:01 to 20061020T00:30:00. This data set contains archival raw, partially processed, and ancillary/supporting radio science data acquired during the Routine Operations phase of the Venus Express (VEX) mission using ground facilities of the European Space Agency (ESA) and/or the NASA Deep Space Network (DSN). This data set was collected during the VEX science subphase 3 (PH3) 2006. For more information see MISSION.CAT. Mission Phase Definition The mission phases which are used in the Data Set Identifier DATA_SET_ID correspond to the following table: Phase name | abbreviation | time span Nominal Mission Phase | NMP | 20051109 20071002 Extended Mission 1 | EXT1 | 20071003 20090531 Extended Mission 2 | EXT2 | 20090601 tbd The mission phases are further divided into science subphases. Mission phase and science subphase definitions can be found in CATALOG/MISSION.CAT and DOCUMENT/ESA_DOC/VEX_ARCHIVE_CONVENTIONS.PDF. Data files Data files are: the tracking files from Deep Space Network (DSN) and from the Intermediate Frequency Modulation System (IFMS) used by the ESA ground station New Norcia, Level 1a to level 2 data are archived, the predicted and reconstructed Doppler and range files, the Geometry files.
