MRO Primary Science Mission SPK (4), JPL SSD Solution MRO95A =========================================================================== Created by Boris Semenov, NAIF/JPL, December 3, 2007. Objects in the Ephemeris -------------------------------------------------------- This file contains ephemeris data for the Mars Reconnaissance Orbiter (MRO) spacecraft. The NAIF ID code for MRO is -74. Approximate Time Coverage -------------------------------------------------------- This file covers the following time period: COVERAGE BEGIN TIME (TDB) COVERAGE END TIME (TDB) ------------------------- ------------------------ 2007 JUL 01 00:01:05.184 2007 OCT 01 01:01:05.182 The coverage provided by the file might have gaps; please, use SPICE utility program BRIEF to get an accurate summary of the available data. Pedigree -------------------------------------------------------- This SPK file contains MRO orbit reconstruction provided by Alex Konopliv of the Solar System Dynamics Group (SSD), JPL. The MRO orbits in this file were generated using the 95th degree and order MRO95A gravity solution which contains entire MGS mission tracking data set and Mars Odyssey and MRO tracking data to the end of August 2007. The data arcs for the orbits are slightly longer than 4 days in length. They were extended so that Doppler data was contained at the beginning and end of the orbit solutions. The orbit overlap errors using a 2-hr overlap were on average 0.5 meters for along the velocity vector and normal to the orbit plane, and 5 cm for the radial component. The normal error increased to about 50 meters during the edge-on geometry phase at the end of June 2007.
