KPL/SCLK MARS 2020 SCLK File =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for MARS 2020 spacecraft on-board clock to UTC conversion. Production/History of this SCLK file -------------------------------------------------------- This file was generated by the NAIF utility program MAKCLK, version 3.5.2, from the most recent MARS 2020 spacecraft SCLKvSCET file (see corresponding sections of these comments for a copy of the source SCLKvSCET file and MAKCLK setup file). Usage -------------------------------------------------------- This file must be loaded into the user's program by a call to the FURNSH subroutine CALL FURNSH( 'this_file_name' ) in order to use the SPICELIB SCLK family of subroutines to convert MARS 2020 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.
