LADEE PC-Kernels ------------------------------------------------------------------------ Version 1.0; September 24, 2014 General Information About SPICE PC-Kernels ========================================== In the SPICE system, the PC-kernels contain planetary attitude and body shape information. The PCK kernel includes orientation and shape information pertaining to extended solar system bodies such as the Sun, the planets, the natural satellites of the planets, comets, and asteroids. The purpose of the PCK kernels and associated software is to provide SPICE users with a convenient mechanism for supplying planetary physical constants to application programs. SPICE's PCK software is able to read files conforming to the PCK format and return to a calling application program both the data contained in such files and a small number of commonly used numeric quantities derived from the kernel data. The SPICE system toolkit for a number of languages and computer platforms can be obtained from the NAIF web site (http://naif.jpl.nasa.gov/). Refer to the ``pck.req'' document provided with the toolkit to get more information on how to access PC-kernel data. LADEE PC-kernel Contained In This Archive ========================================= The following LADEE PC-kernels are provided in this archive: pck000010.tpc generic SPICE PCK file based on the 2009 IAU constants. moon_pa_de421_1900_2050.bpc PcK file containing high-accuracy lunar orientation data from the JPL Solar System Dynamics Group's planetary ephemeris DE421. This kernel yields the orientation the the lunar principal axes (PA) reference frame (defined by DE421) relative to the ICRF. Applications using this file will also need to load a generic lunar frame kernel also provided in this data set. Kernel File Details =================== The most detailed description of the data in a text PCK file is provided in metadata included inside the description area of the file. This information can be viewed using any text editor program. The most detailed description of the data in a binary PCK file is provided in metadata included inside the comment area of the file. This information can be viewed using utility programs COMMNT and SPACIT included into the NAIF Toolkit.
