KPL/SCLK Solar Orbiter SCLK File =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for the Solar Orbiter (SOLAR ORBITER) spacecraft on-board clock to UTC conversion. This file contains the data necessary for converting from ET to ticks for the FICTIONAL SOLAR ORBITER spacecraft clock (clock ID code 144). Note that although the SCLK is fictional is named is if it was a REAL SCLK clock. This is intended for study purposes using test models 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 was generated by the NAIF utility program MAKCLK from the most recent SOLAR ORBITER Time Correlation Packet (TCP) data. This SCLK kernel is intended to be used with test CK files with structure IDs listed below on board the spacecraft -144 (SOLO): SOLO_SPACECRAFT -144000 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 in order to use the SPICELIB SCLK family of subroutines to convert SOLAR ORBITER 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.
