Data file names have been changed to yyyy_ddd_zzzz_eee_tro.csp where yyyy and zzzz give the start and end year of data and ddd and eee give the start and end days of year. The PDS4 label file name is yyyy_ddd_zzzz_eee_tro.xml. 2016-10-01T03:00:00.001Z 2016-11-01T03:00:00.000Z Calibration Derived DSN tropospheric calibrations for radio science observations. NASA Deep Space Network Media Calibration Other Investigation urn:nasa:pds:context:investigation:other_investigation.media.dsn data_to_investigation Global Positioning System Instrument Path delays from multi-frequency observations of GPS satellites are used to model path delays along the DSN-to-spacecraft radio link resulting from passage through Earth's troposphere as a function of time. urn:nasa:pds:context:instrument:dsn.media is_instrument Earth Planet Dual-frequency GPS radio signals penetrate Earth's troposphere, providing information on path delay that can be used to calibrate radio tracking data. urn:nasa:pds:context:target:planet.earth data_to_target urn:nasa:pds:radiosci.documentation:dsn.trk-2-23:2008-03-05 data_to_document For pre-2008 files, consider looking at an earlier SIS in the same collection. 2016_275_2016_306_tro.csp 2026-04-09T17:52:32 148532 89cf195722104ed6204f96bbb2338844 0 7-Bit ASCII Text Line-Feed
