R. 2020 MESSENGER Radio Science Tracking and Navigation File (TNF) 2020-10-12 1.0 This data file has been migrated from PDS3 PRODUCT_ID 071551935SC236DSS14_234 in data set MESS-V/H-RSS-1-EDR-RAWDATA-V1.0 to PDS4. The data file has been sorted according to data type and a new PDS4 label was created as part of the migration process. 2007-06-04T18:07:51Z 2007-06-05T05:20:53Z Science Raw MESSENGER raw radio tracking data Radio Science MErcury Surface, Space ENvironment, GEochemistry, and Ranging Mission Mission urn:nasa:pds:context:investigation:mission.messenger data_to_investigation MESSENGER Spacecraft urn:nasa:pds:context:instrument_host:spacecraft.mess is_instrument_host RSS Instrument urn:nasa:pds:context:instrument:rss.mess is_instrument NASA Deep Space Network Observatory urn:nasa:pds:context:facility:observatory.dsn is_facility DSN Instrumentation Instrument urn:nasa:pds:context:instrument:dsn.rss is_instrument DSN Antenna DSS 14 Telescope urn:nasa:pds:context:telescope:goldstone.dss14_70m is_telescope Venus Planet urn:nasa:pds:context:target:planet.venus data_to_target urn:nasa:pds:radiosci.documentation:dsn.trk-2-34:2002-12-15 data_to_document Reference document for the Tracking and Navigation File (TNF) data. For data collected earlier or later than this document, consult other document products in the same collection. IMPORTANT: Records delivered originally by the DSN were in time order, with records for different TNF data types interleaved. Retaining that structure would have made the PDS label many times larger than the data file itself. To keep the size of the label manageable, the original file was sorted so that all records of a single TNF data type are together. The blocks of homogeneous records were then concatenated -- TNF data type 0, followed by TNF data type 1, ... followed by TNF data type 17. When there were no records of a given TNF data type, that block was omitted. Within each block, the records remain in time order. The label is still long, since each block is a Table_Binary with many records containing many fields. But there will never be more than 18 blocks and never more than 18 Table_Binary definitions. The document referenced here correctly describes the record formats. Note, however, that the records are no longer in absolute time order. They are in time order within each block and the blocks are ordered by TNF data type.
