KPL/SCLK RM SCLK File -- TEST DATA -- FICTIONAL =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for ExoMars RSP Rover Module (RM) on-board clock to UTC conversion. This file contains the data necessary for converting from ET to ticks for the FICTIONAL RM spacecraft clock (clock ID code 174) This is intended for study purposes or for those situations in which a clock is not available for the structure whose orientation will be modelled by a C-kernel. Production/History of this SCLK file -------------------------------------------------------- This file has been manually created by Marc Costa Sitja (ESAC/ESA) and contains FICTIONAL DATA. It is intended ONLY for study purposes. NO DATA ANALYSIS SHALL BE PERFORMED BASED ON THIS FILE. This SCLK kernel is intended to be used with test CK files with structure IDs listed below on board the rover -174 (RM): RM_ROVER -174000 Usage -------------------------------------------------------- This file must be loaded into the user's program by a call to the FURNSH subroutine CALL FURNSH ( 'this_file_name; ) -- FORTRAN furnsh_c ( "this_file_name" ); -- C cspice_furnsh, 'this_file_name' -- IDL cspice_furnsh( 'this_file_name' ) -- MATLAB spiceypy.furnsh( 'this_file_name' ) -- PYTHON in order to use the SPICELIB SCLK family of subroutines to convert RM_ROVER spacecraft on-board clock to ET and vice versa. SCLK Format -------------------------------------------------------- The on-board clock, the conversion for which is provided by this SCLK file, consists of two fields: SSSSSSSSSS.FFFFF where: SSSSSSSSSS -- count of on-board seconds FFFFF -- count of fractions of a second with one fraction being 1/65536 of a second; normally this field value is within 0..65535 range.

For all time, the clock runs at the same rate as TDB. There is only one partition for this clock. \begindata SCLK_KERNEL_ID = ( @2019-11-28 ) SCLK_DATA_TYPE_174 = ( 1 ) SCLK01_TIME_SYSTEM_174 = ( 1 ) SCLK01_N_FIELDS_174 = ( 2 ) SCLK01_MODULI_174 = ( 4294967296 65536 ) SCLK01_OFFSETS_174 = ( 0 0 ) SCLK01_OUTPUT_DELIM_174 = ( 1 ) SCLK_PARTITION_START_174 = ( 0 ) SCLK_PARTITION_END_174 = ( 2.81474976710656E14 ) SCLK01_COEFFICIENTS_174 = ( ) \begintext End of SCLK file.
