KPL/SCLK (draft) ExoMars-16 TGO SCLK File =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for time conversions between the ExoMars Trace Gas Orbiter spacecraft on-board clock and Ephemeris Time (ET). Status -------------------------------------------------------- This SCLK file provide the DRAFT version of nominal correlation for the TGO on-board clock initialized at "0:0" on 2016-04-18/20:00:00 UTC and running at same rate as UTC. Pedigree -------------------------------------------------------- This file was generated by the NAIF utility program MAKCLK that converted a linear-piece TGO clock correlation function provided in a SCLKvSCET format file to SPICE SCLK kernel file. Usage -------------------------------------------------------- In order to use the SPICELIB SCLK family of subroutines to convert TGO spacecraft on-board clock to ET and vice versa this file must be loaded into the user's program by a call to the FURNSH routine: CALL FURNSH ( 'frame_kernel_name; ) -- FORTRAN furnsh_c ( "frame_kernel_name" ); -- C cspice_furnsh, frame_kernel_name -- IDL cspice_furnsh( 'frame_kernel_name' ) -- MATLAB SCLK Format -------------------------------------------------------- The on-board clock, the conversion for which is provided by this SCLK file, consists of two fields: DDDD:MMMMMMMM where: DDDD -- the count of on-board days, 0 to 9999 MMMMMMMM -- the count of on-board milliseconds with an on-board day, 0...86399999 References -------------------------------------------------------- 1.
