INSIGHT Cruise SPK file, JPL NAV OPS Solution =========================================================================== Created by Eric Gustafson, INSIGHT NAV Team/JPL, on April 29, 2019; comments added by Boris Semenov, NAIF/JPL, May 2, 2019. Objects in the Ephemeris -------------------------------------------------------- This file contains the reconstructed cruise trajectory for INSIGHT. The NAIF ID code for INSIGHT is -189. Approximate Time Coverage -------------------------------------------------------- This file covers the whole cruise phase of the INSIGHT mission: COVERAGE BEGIN TIME (ET): 2018 MAY 05 12:39:28.965 COVERAGE END TIME (ET): 2018 NOV 26 19:40:12.526 Status -------------------------------------------------------- This file was prepared for archiving in the Planetary Data System (PDS). Pedigree -------------------------------------------------------- This file starts approximately 1.5 hours after launch, and ends at the EDL interface time. It is a merge of six trajectories created during the cruise orbit determination process. The source SPKs and their valid time intervals in the combined trajectory are: nsyt_spk_cruise_od003_v1.bsp: 2018 MAY 05 12:39:28.965 ET to 2018 MAY 05 21:00:00.000 ET nsyt_spk_cruise_od038_v1.bsp: 2018 MAY 05 21:00:00.000 ET to 2018 JUN 08 00:00:00.000 ET nsyt_spk_cruise_od091_v1.bsp: 2018 JUN 08 00:00:00.000 ET to 2018 SEP 11 07:01:09.182 ET nsyt_spk_cruise_od106_v1.bsp: 2018 SEP 11 07:01:09.182 ET to 2018 OCT 12 19:00:00.000 ET nsyt_spk_cruise_od116_v1.bsp: 2018 OCT 12 19:00:00.000 ET to 2018 NOV 18 19:01:09.182 ET nsyt_spk_cruise_od133_v1.bsp: 2018 NOV 18 19:01:09.182 ET to 2018 NOV 26 19:40:12.526 ET The details of force modeling evolved throughout cruise, but each leg in this trajectory accounts for trajectory correction maneuvers, attitude control system thruster firings, solar radiation pressure, and outgassing. The original name of this file was insight_ops_v1.bsp. Usage -------------------------------------------------------- This file should be used together with DE430 planetary ephemeris and MAR097 satellite ephemeris.
