urn:nasa:pds:nh_rex:kem1cruise_tnf 1.0 1.19.0.0 Product_Collection Linscott, I. Kahan, D.; Hirsch, B. 2026 10.26007/baj0-ef52 This data set contains Tracking and Navigation Files (TNF) created for the New Horizons Radio Science Experiment (REX) instrument during the KEM1 Cruise mission phase. The collection includes uplink tuning profile data in, and extracted from, Tracking and Navigation Files (TNFs) for all CORE observations. Although uplink data signals were sent from the Ground Element to REX during the Approach sub-phase, tuning profiles for those signals are not provided as they are not needed to analyze those REX Approach observations comprising instrument checkout, characterization and calibration activities. 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 planetary encounters. Specifically, this collection is associated with solar conjunction observations, SNR verification, radio path characterization, and bistatic dry run. These data were migrated from the previously released PDS3 data set NH-X-REX-2-KEMCRUISE1-V2.0. 2026-07-28 1.0 Created during PDS4 migration by PDS-SBN (B.
