KPL/FK Topocentric Reference Frame Definition Kernel for DSN Station DSS-59 ===================================================================== Original file name: dss_59_prelim_itrf93_220921.tf Creation date: 2022-09-21 16:00 Created by: Nat Bachman (NAIF/JPL) Introduction ===================================================================== This file defines a topocentric reference frame associated with the DSN station DSS 59, based on preliminary station location data from source [1]. Associated SPK file ------------------- This file is compatible with the SPK file dss_59_prelim_itrf93_220921.bsp [reference frame: ITRF93] which provides a state vectors for the station DSS 59. Most applications will need to load this SPK file in order to make use of this frame kernel. Data sources ===================================================================== The data provided here were provided in an email from Connie Dang (JPL), received 2022-09-13.
