MESSENGER Radio Science Tracking and Navigation (TNF) Data Products Collection
This is the collection of Radio Science Tracking and Navigation (TNF) data products acquired during the MESSENGER mission. Data were originally stored as chronological records in DSN format TRK-2-34; but they have been sorted according to data type (retaining chronological order within each data type) during migration from PDS3 to PDS4. -
bundle:
MESSENGER RSS Raw Data Bundle
This bundle contains raw radio data that can be used to determine the position and velocity of the MESSENGER spacecraft during flybys of Venus and Mercury and during orbital operations around Mercury. The bundle also contains measurements of occultation times and calibrations for the effects of Earth's ionosphere and troposphere, meteorological conditions at stations of the NASA Deep Space Network, thruster activity, and changes in spacecraft antenna selection. The data were used to determine the gravity field and shape of Mercury and to improve solar system ephemerides. The bundle is a migration of data from the original PDS3 archive with minor improvements and corrections.
