LADEE C-Kernels ------------------------------------------------------------------------ Version 1.1; November 13, 2014 General Information About SPICE C-Kernels ========================================= In the SPICE system, pointing data for an instrument platform, or for a specific instrument, are stored C-kernels. The pointing of a platform or an instrument is often expressed in terms of a transformation matrix from some standard inertial reference frame to a instrument-fixed frame. In the past, the instrument was often a camera, and the transformation was thus dubbed the ``C-matrix''; hence the choice of C as the name for the pointing kernel. The data contained in C-kernel files can be accessed and manipulated using the SPICE Toolkit APIs, calls to which can be integrated into user application programs. 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/). To use C-kernels, a Spacecraft Clock Kernel (SCLK) is required. Also, for C-Kernels containing orientation of a project-defined frames, a Frame Definitions File is required. Refer to the ``ck.req'' document provided with the toolkit or available from the NAIF Node of PDS to get more information on how to access C-kernel data. LADEE C-kernels Provided in This Archive ======================================== The following LADEE C-kernels are provided in this archive: ladee_13250_13330_v04.bc the complete LADEE reconstructed ladee_13330_14030_v04.bc spacecraft orientation CK files ladee_14030_14108_v04.bc covering the whole LADEE mission. These CK files supersede the ``v03'' CK file described below. ladee_13250_14108_v03.bc the incomplete LADEE reconstructed spacecraft orientation CK file covering the whole LADEE mission. This CK file is superseded by the ``v04'' CK files described above. Kernel File Details =================== The most detailed description of the data in a binary CK 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.
