KPL/IK INSIGHT Auxiliary Instrument Kernel =============================================================================== This Instrument Kernel (IK) file contains Field-Of-View (FOV) definitions for a few INSIGHT instruments and structures that don't yet or will never have their own IKs. Version and Date ------------------------------------------------------------------------------- Version 0.0 -- September 18, 2014 -- Boris Semenov, NAIF Initial Release. References ------------------------------------------------------------------------------- 1. Kernel Pool Required Reading 2. GETFOV, getfoc_c, cspice_getfov headers 3. INSIGHT FK file, latest version Contact Information ------------------------------------------------------------------------------- Boris V. Semenov, NAIF/JPL, (818)-354-8136, Boris.Semenov@jpl.nasa.gov Implementation Notes ------------------------------------------------------------------------------- This file is used by the SPICE system as follows: programs that make use of this kernel must ``load'' the kernel, normally during program initialization. The SPICE routine FURNSH loads a kernel file into the pool as shown below. CALL FURNSH ( 'frame_kernel_name; ) -- FORTRAN furnsh_c ( "frame_kernel_name" ); -- C cspice_furnsh, frame_kernel_name -- IDL cspice_furnsh( 'frame_kernel_name' ) -- MATLAB Once the file has been loaded, the SPICE routine GETFOV (getfov_c in C, cspice_getfov in IDL and MATLAB) can be used to retrieve FOV parameters for a given instrument or structure. This file was created and may be updated with a text editor or word processor. Naming Conventions ---------------------------------------------------------- All names referencing values in this IK file start with the characters `INS' followed by the NAIF INSIGHT ID number (-189) followed by a NAIF three digit ID code for one of the structures. This is the full list of names and IDs for the structures described by this IK file: INSIGHT_CLGA_TX -189410 INSIGHT_CLGA_RX -189420 INSIGHT_CMGA -189430 INSIGHT_LMGA_EAST -189440 INSIGHT_LMGA_WEST -189450 INSIGHT_HELIX -189460 INSIGHT_WPA -189470 The remainder of the keyword name is an underscore character followed by the unique name of the data item. For example, the Cruise MGA boresight direction in the HGA frame is specified by: INS-189430_BORESIGHT The upper bound on the length of the name of any data item is 32 characters. If the same item is included in more than one file, or if the same item appears more than once within a single file, the latest value supersedes any earlier values.
