DSPSE SPICE SCLK Kernel -------------------------------------------------------- This file contains the data necessary to convert between DSPSE spacecraft clock time (SCLK) and ephemeris time. NAIF suggests that you do not modify this file. If you do modify it, be sure to indicate this in the `Version' section below. Version -------------------------------------------------------- This file is DSPSE version 1, released 18-JAN-1994. Implementation notes -------------------------------------------------------- You must load this file into the kernel pool before using any of the SPICELIB SCLK routines. The code fragment CALL LDPOOL ( < name of this file > ) performs this task. To convert between ET and UTC, you will also need to load a leapseconds kernel. The additional call to LDPOOL, CALL LDPOOL ( < name of your leapsecond file > ) will accomplish this. Note that you must supply the actual names of the files used on your system as arguments to LDPOOL. Because the file names are system dependent, we do not list them here. For more information, consult your SPICELIB required reading files. The following areas are covered: SCLK system SCLK required reading Time systems and conversion TIME required reading Kernel pool KERNEL required reading Kernel data -------------------------------------------------------- The DSPSE clock zero count occurs at 1-JAN-1950/00:00:00 UTC. Nominally, the clock will advance at UTC time. When a leapsecond occurs, the clock will be adjusted accordingly. When this event occurs, a new partition must be added to this file. To account for leapseconds prior to the launch of the spacecraft, the begin time below is 1-JAN-1950/00:00:19.000. \begindata SCLK_KERNEL_ID = ( @1994-01-18 ) SCLK_DATA_TYPE_40 = ( 1 ) SCLK01_TIME_SYSTEM_40 = ( 2 ) SCLK01_N_FIELDS_40 = ( 3 ) SCLK01_MODULI_40 = ( 65536 10546.875 65536 ) SCLK01_OFFSETS_40 = ( 0 0 0 ) SCLK01_OUTPUT_DELIM_40 = ( 1 ) SCLK_PARTITION_START_40 = ( 0.0000000000000E+00 ) SCLK_PARTITION_END_40 = ( 4.5298483199999E+13 ) SCLK01_COEFFICIENTS_40 = ( 0.0000000000000E+00 -1.5778799398160E+09 8.6400000000000E+04 ) \begintext
