New Horizons REX KEM1 Encounter Tracking and Navigation Files

A PDS3 version of this data set can be found here.

Status: LOCALLY ARCHIVED

Abstract: This data set contains Tracking and Navigation Files (TNF) created for the New Horizons Radio Science Experiment (REX) instrument during the KEM1 ENCOUNTER mission phase. The collection includes TRK-2-34 radiometric tracking data files and TRK-2-23 media calibration files. The media calibration data that are provided by the Radiometric Modeling and Calibration Subsystem (RMC). These calibrations are used by project navigation and radio science teams, multi-mission spacecraft navigation, and other investigators to improve the accuracy of spacecraft orbit determination and radio science investigations by compensating for the media transmission effects of the Earth's troposphere and ionosphere on the propagation of radiometric signals. This version includes data acquired by the spacecraft between 08/14/2018 and 04/30/2022. It only includes data downlinked before 05/01/2022. Future datasets may include more data acquired by the spacecraft after 08/13/2018 but downlinked after 04/30/2022. The REX datasets over the mission include calibrations using known radio sources, Jupiter, and cold sky measurements; operational readiness tests (ORTs); internal test pattern calibration; and prime science radiometry and occultation observations during the Arrokoth Encounter. These data were migrated from the previously released PDS3 data set NH-A-REX-3-KEM1-V5.0.
