DAF/CK em16_tgo_sc_fmp_024_01_{start_date}_{finish_date}_f20180215_ _ LTL-IEEE FTPSTR: : : : :::ENDFTP ExoMars2016 TGO CK file by ESA SPICE Service =========================================================================== This file contains quaternions and angular rates of the TGO spacecraft extracted from the corresponding long and mid term planning predicted attitude data AEM file produced by Fight Dynamics on December 4, 2019. It has been created with the utilities AEM2CK and MSOPCK by the ESA SPICE Service on December 4, 2019. Objects -------------------------------------------------------- This file contains orientation and angular velocity data for the ExoMars2016 TGO spacecraft frame, 'TGO_SPACECRAFT', relative to the Earth Mean Equator and Equinox of J2000, J2000. The NAIF ID code for TGO_SPACECRAFT is -143000. Approximate Time Coverage ------------------------------------------------------------------------ Begin UTC: 2020-JAN-25 12:12:13.999 End UTC: 2020-FEB-22 13:15:17.000 Status ------------------------------------------------------- ----------------- This kernel is an operational product of the ExoMars2016 TGO Science Operations Team. It is intended to be used by ExoMars2016 TGO science operations engineers for science planning and it contains predicted data. Please note that since this is a planning kernel it has been generated with a fictional SCLK kernel due to the fact that successive updates of the real SCLK kernel will lead to erroneous results for the predicted data provided by those kernels after the last Time Correlation Packet that the real SCLK contains. The alternative of re-generating the planning CKs with the latest SCLK kernel is not considered. In order to be able to use the long and mid term planning CKs with the measured and short term planning CKs the planning CKs are generated with the fictional SCLK and are defined relative to the ExoMars2016 TGO spacecraft planning reference frame -- TGO_SPACECRAFT_PLAN --. This planning CK is appended with MSPO CK with a CK segment generated with the real SCLK that maps the TGO_SPACECRAFT_PLAN to the TGO_SPACECRAFT reference frame thus allowing to use both planning and measured CK files together with correct results. Note that when new SCLK are available the segment boundaries of the planning CKs will be affected. Due to this reason, the mapping segments boundaries are adjusted inwards by a minute on each side to get a better chance of them always being within the original CK segment boundaries. Pedigree ------------------------------------------------------------------------ ESOC/FD is responsible for Auxiliary Data delivering. This file has been created using AEM2CK and MSOPCK using as input the AEM file delivered by the ExoMars2016 TGO Mission Operations Center to thenExoMars2016 TGO Science Operations Team on December 4, 2019, and the configuration file appended at the end of this comments section. TGO source file name = SATM_DM_024_01_01___ A IfiͿT+ _00437.EXM Usage ------------------------------------------------------------------------ This file should be used together with the kernel set described below: em16_tgo_v18.tf a Frame Kernel file required to establish relationships between frames used in geometry computations. naif0012.tls a Leapseconds Kernel file is used in conversions between ephemeris time and UTC (coordinated universal time). em16_tgo_fict_20180215.tsc a Spacecraft Clock Kernel file is used in conversions between the TGO Clock time and ephemeris time. The usage of this CK with other versions of these files shall be analysed and handled with care.
