The position data from that email are shown below: LAT = 38.19188139 deg LON = 276.56112556 deg ALT = 363.648 meters The email states that the position in the ITRF93 reference frame, Epoch 2003.0, with respect to the WGS84 spheroid (Re = 6378137 meters, Rp = 6356752.314 meters) and might be in error by several centimeters. No velocity data were provided with the position information. begindata SITES += 'DSS-17' DSS-17_FRAME = 'ITRF93' DSS-17_CENTER = 399 DSS-17_IDCODE = 399017 DSS-17_BOUNDS = ( @1950-JAN-01/00:00, @2050-JAN-01/00:00 ) DSS-17_LATLON = ( 38.19188139 276.56112556 0.363648 ) DSS-17_UP = 'Z' DSS-17_NORTH = 'X' begintext Earth RADII for DSN kernel generation ===================================== Author: Boris Semenov (NAIF/JPL) File creation date: 10-NOV-2016 Reference Spheroid ------------------ The reference spheroid radii provided in an email from Dr. Stephen Slobin dated November 09, 2016 were: The semi-major axis of the WGS84 ellipsoid, outward in the x-direction from the geocenter to the equator = a = 6378137 meters.
