PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT INTERCHANGE_FORMAT = ASCII PUBLICATION_DATE = 2022-09-26 NOTE = "SP-Kernel Information" END_OBJECT = TEXT END General information about SPICE SP-kernels ========================================== The purpose of the SP-kernel -- which stands for S(pacecraft) and P(lanet) Kernel -- is to allow ephemerides for any collection of solar system bodies, spacecraft or any other objects in 3D space to be combined under a common file format, and accessed by a common set of subroutines. The SPK format is supported by a collection of subroutines that are part of the SPICELIB library, the major component of the NAIF Toolkit. These subroutines can be integrated into user application programs. The SPICE system toolkit for a number of computer platforms or information regarding how it can be obtained is located in the SOFTWARE subdirectory of the main directory of this dataset. To use SP-kernels, a Leapseconds (LSK) is required. Also, to use SP-Kernels containing positions given relative to the non-inertial and project-defined frames, a Frame Definitions (FRAMES) and Planetary Constants (PcK) files are required. Refer to the SPK.REQ document provided with the toolkit or available from the NAIF Node of PDS if SPICE toolkit is not included with this data set to get more information on how to access SP-kernel data. Odyssey (M01) SP-kernels provided in this directory =================================================== This directory contains the SPICE SP-Kernel files for the Odyssey mission. All files are in IEEE binary format and suitable for ftp binary transfer to use on UNIX workstations and MACs. The following files are present in this directory. (Only file names are shown; the file name extensions of the binary SPK files are always ".bsp"): Spacecraft Trajectory SPK files: m01_PPPPPP Final merged spacecraft trajectory SPKs for cruise, aerobraking, mapping and extended phases of the mission. These files were made by merging reconstructed OD SPK files produced by Odyssey NAV. The letters ``PPPPPP'' indicate the mission phase or the portion of the mission phase covered by the file and map to the actual coverage dates as follows: Part of Map Start UTC Stop UTC ----------- ---------- ---------- cru 2001-04-07 2001-10-23 ab 2001-10-24 2002-02-18 map1 2002-02-19 2002-03-31 (1) map2 2002-04-01 2002-06-30 map3 2002-07-01 2002-09-30 map4 2002-10-01 2002-12-31 map5 2003-01-01 2003-03-31 map6 2003-04-01 2003-06-30 map7 2003-07-01 2003-09-30 map8 2003-10-01 2003-12-31 map9 2004-01-01 2004-03-31 map10 2004-04-01 2004-06-30 map11 2004-07-01 2004-09-30 (2) ext1 2004-10-01 2004-12-31 (2) ext2 2005-01-01 2005-03-31 ext3 2005-04-01 2005-06-30 ext4 2005-07-01 2005-09-30 ext5 2005-10-01 2005-12-31 ext6 2006-01-01 2006-03-31 ext7 2006-04-01 2006-06-30 ext8 2006-07-01 2006-09-30 ext9 2006-10-01 2006-12-31 ext10 2007-01-01 2007-03-31 ext11 2007-04-01 2007-06-30 ext12 2007-07-01 2007-09-30 ext13 2007-10-01 2007-12-31 ext14 2008-01-01 2008-03-31 ext15 2008-04-01 2008-06-30 ext16 2008-07-01 2008-09-30 ext17 2008-10-01 2008-12-31 ext18 2009-01-01 2009-03-31 ext19 2009-04-01 2009-06-30 ext20 2009-07-01 2009-09-30 ext21 2009-10-01 2009-12-31 ext22 2010-01-01 2010-03-31 ext23 2010-04-01 2010-06-30 ext24 2010-07-01 2010-09-30 ext25 2010-10-01 2010-12-31 ext26 2011-01-01 2011-03-31 ext27 2011-04-01 2011-06-30 ext28 2011-07-01 2011-09-30 ext29 2011-10-01 2011-12-31 ext30 2012-01-01 2012-03-31 ext31 2012-04-01 2012-06-30 ext32 2012-07-01 2012-09-30 ext33 2012-10-01 2012-12-31 ext34 2013-01-01 2013-03-31 ext35 2013-04-01 2013-06-30 ext36 2013-07-01 2013-09-30 ext37 2013-10-01 2013-12-31 ext38 2014-01-01 2014-03-31 ext39 2014-04-01 2014-06-30 ext40 2014-07-01 2014-09-30 ext41 2014-10-01 2014-12-31 ext42 2015-01-01 2015-03-31 ext43 2015-04-01 2015-06-30 ext44 2015-07-01 2015-09-30 ext45 2015-10-01 2015-12-31 ext46 2016-01-01 2016-03-31 ext47 2016-04-01 2016-06-30 ext48 2016-07-01 2016-09-30 ext49 2016-10-01 2016-12-31 ext50 2017-01-01 2017-03-31 ext51 2017-04-01 2017-06-30 ext52 2017-07-01 2017-09-30 ext53 2017-10-01 2017-12-31 ext54 2018-01-01 2018-03-31 ext55 2018-04-01 2018-06-30 ext56 2018-07-01 2018-09-30 ext57 2018-10-01 2018-12-31 ext58 2019-01-01 2019-03-31 ext59 2019-04-01 2019-06-30 ext60 2019-07-01 2019-09-30 ext61 2019-10-01 2019-12-31 ext62 2020-01-01 2020-03-31 ext63 2020-04-01 2020-06-30 ext64 2020-07-01 2020-09-30 ext65 2020-10-01 2020-12-31 ext66 2021-01-01 2021-03-31 ext67 2021-04-01 2021-06-30 ext68 2021-07-01 2021-09-30 ext69 2021-10-01 2021-12-31 ext70 2022-01-01 2022-03-31 ext71 2022-04-01 2022-06-30 ext72 2022-07-01 2022-09-30 ext73 2022-10-01 2022-12-31 ext74 2023-01-01 2023-03-31 ext75 2023-04-01 2023-06-30 ext76 2023-07-01 2023-09-30 ext77 2023-10-01 2023-12-31 (1) the ``map1'' file is shorter than three months to align the file coverage boundaries with the project-wide archive period cut-off dates. (2) although the extended mission started in August 2004, ``map11'' file goes through the end of September and ``ext1'' file starts on October 1 to keep the file coverage begins/ends at three month boundaries. Note that ``m01_map1'' released in June 2002 and covering through 2002-05-31 has been replaced with two files containing exactly same data -- ``m01_map1_v2'' covering through 2002-03-31 and ``m01_map2'' covering from 2002-04-01. This was done to align the file coverage boundaries with the project-wide archive period cut-off dates, as requested by the project's DAWG. m01_PPPPPP_ipng_mgs95j trajectory SPK files for mapping and extended phases of the mission created by Alex Konopliv of the SSD group (formerly of the IPNG group), JPL, using the Mars gravity model MGS95J. The letters ``PPPPPP'' indicate the mission phase or the portion of the mission phase as specified above m01_PPPPPP_ssd_mro110c trajectory SPK files for mapping and extended phases of the mission created by Eugene Fahnestock of the SSD group (formerly of the IPNG group), JPL, using the Mars gravity model MRO110C. The letters ``PPPPPP'' indicate the mission phase or the portion of the mission phase as specified above Odyssey spacecraft structures SPK file: m01_struct_v10 SPK file containing relative locations of Odyssey solar array and HGA structures. Solar System Bodies Ephemeris data SPK file: de405s SPK file containing JPL's Planetary Ephemerides (DE) 405. Satellite Ephemeris data SPK files: mar033_5 This file contains ephemerides for the Martian satellites Phobos and Diemos, and for the Sun, Earth, Moon and Mars. mar033_7 The same version of ephemerides for the Martian satellites but with slightly longer coverage. mar063 This file contains version MAR063 ephemerides for the Martian satellites Phobos and Diemos, and for the Sun, Earth, Moon and Mars. This file supersedes the mar033* files.
