ExoMarsRSP SPK files =========================================================================== This ``aareadme.txt'' file describes the contents of the kernels/spk directory of the ExoMarsRSP SPICE Kernel Dataset. It was last modified on January 11, 2023 by Ricardo Valles, ESAC/ESA. Brief Summary -------------------------------------------------------- This directory contains the SPICE SP-Kernel files for the ExoMarssRSP mission, including mission analysis, nominal and operational rover trajectory SPKs, generic planetary and satellite ephemeris SPKs. File naming conventions -------------------------------------------------------- Naming Scheme for ExoMarsRSP rover SPKs: Naming scheme for SPKs describing landing site and sites position is: emrsp_rm[_test]_TYPE_vNNN.bsp where TYPE: Variable char that specifies the type of SPK file, its values are: sites: This file provides the position of site frames with respect to the MCMF frame. These frames are instantiated after each absolute localizations, normally after long travelings. ls-plan: This file contains the location of the landing site, as planned, with respect to the MCMF frame. ls-real: This file contains the actual location of the landing site, as measured after landing, with respect to the MCMF frame. test: This file include data that is used for test or rehearsal (optional). Naming scheme for SPKs describing the rover and its mechanisms position. emrsp_rm[_test]_TYPE[_XXXX]_vNNN.bsp where TYPE: Variable char that specifies the type of SPK file, its values are: gnc-zero: file including gnc zero position of the rover with respect to landing site. gnc-tlm: file including gnc telemetry from the rover with respect to site frames (including landing frame). mech-tlm: file including drill prismatic joint information and cstm prismatic joint information as per rover telemetry with respect to rover attached frames. interp-tlm: file including rover gnc and mechanisms telemetry interpolated with data gaps filled assuming rover they are not moving if telemetry is not available. This kernel will include the gnc position extrapolated with a zero order interpolation for 7 sols beyond the latest telemetry received to allow for rover-orbiter link budget calculation. rec: file including the rover position relative to MCMF or geodetic coordinates or WISDOM grid position relative to the latest site frame. test: This file include data that is used for test or rehearsal (optional). XXXX: Kernel generation sol number, this corresponds to the end sol of its telemetry coverage. This number is 4 digits long and left padded with 0s starting from 0. This field is optional in case of kernels of type test. This number corresponds to the one appearing in the OEM filename. NNN: 3 digit version number, incremental, starting from 0. Naming scheme for file describing the fixed structural offsets among rover frames, including both rover and instruments ones. emrsp_rm_struct_vNNN.bsp where NNN: 3 digit version number, incremental, starting from 0. Naming Scheme for Generic Planetary Ephemeris SPKs The naming scheme for generic planetary SPKs is: deNNNs.bsp where NNN: DE version (required; e.g. 432); Naming Scheme for Generic Mars Satellite Ephemeris SPKs The naming scheme for generic mars satellite SPKs is: marNNN[_EXTRA].bsp where NNN: satellite ephemeris number (required; e.g. 083); EXTRA: additional information token (optional); Naming Scheme for ESA ESTRACK ground stations SPKs The naming scheme for ESA ESTRACK ground stations SPKs is: estrack_vNN.bsp where NN: version (required; e.g. 01); Naming Scheme for ESA New Norcia ground station SPKs The naming scheme for ESA New Norcia ground stations SPKs is: new_norcia.bsp Naming Scheme for ExoMarsRSP surface platform SPKs: Naming scheme for SPKs describing the surface platform and its mechanisms position. emrsp_sp_TYPE_vNNN.bsp where TYPE: Variable char that specifies the type of SPK file, its values are: gnc-zero: file including gnc zero position of the surface platform with respect to landing site. NNN: 3 digit version number, incremental, starting from 0. Naming scheme for file describing the fixed structural offsets among surface platform frames, including both surface platform and instruments ones. emrsp_sp_struct_vNNN.bsp where NNN: 3 digit version number, incremental, starting from 0.
