NAIF ID code for NEAR is -93. The landed NEAR spacecraft location stored in this file is a fixed vector with respect to the Eros center (2000433) in the Eros body-fixed frame ('EROSFIXED'). Approximate Time Coverage -------------------------------------------------------- The coverage of this file extends from the surface touchdown time through January 1, 2010: COVERAGE BEGIN TIME (ET) COVERAGE END TIME (ET) ------------------------ ------------------------ 2001 FEB 12 19:45:20.000 2010 JAN 01 00:00:00.000 Coordinate Source -------------------------------------------------------- This SPK file is based on the landing site location estimate provided by Peter G. Antreasian of the NEAR NAV team at JPL: x = 0.802 km +/- 50 m y = 4.872 km +/- 10 m z = -4.147 km +/- 150 m radius = 6.447 km Latitude = -40.03 deg East Longitude = 80.66 deg Pedigree -------------------------------------------------------- This file was created using PINPOINT Utility Program. The input to the program was the landed spacecraft location Cartesian vector in with respect to the Eros center in the EROSFIXED frame (see Appendix 1 for PINPOINT inputs.) Since EROSFIXED frame is not one of the frames built into SPICE, the definition for this frame consisting of the following keywords: \begindata FRAME_EROSFIXED = 2000433 FRAME_2000433_NAME = 'EROSFIXED' FRAME_2000433_CLASS = 2 FRAME_2000433_CLASS_ID = 2000433 FRAME_2000433_CENTER = 2000433 OBJECT_2000433_FRAME = 'EROSFIXED' \begintext should be made available to the SPICE system by cut-n-pasting these keywords into a text and loading it using FURNSH routine.
