KPL/IK MSL Structures Instrument Kernel =============================================================================== This Instrument Kernel (IK) file contains Field-Of-View (FOV) definitions for MSL antennas (HGA, MGA, LGAs, UHFs). Version and Date ------------------------------------------------------------------------------- Version 0.1 -- July 27, 2012 -- Boris Semenov, NAIF Changed IDs to match the latest name/ID mapping. Version 0.0 -- May 3, 2011 -- Boris Semenov, NAIF Initial Release. References ------------------------------------------------------------------------------- 1. Kernel Pool Required Reading 2. GETFOV, getfoc_c, cspice_getfov headers 3. MSL 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 MSL ID number (-76) 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: MSL_PLGA -76060 MSL_TLGA -76061 MSL_PUHF -76062 MSL_MGA -76063 MSL_DLGA -76064 MSL_DUHF -76065 MSL_RLGA -76110 MSL_RUHF -76111 MSL_HGA -76125 MSL_HGA_EB -76126 The remainder of the keyword name is an underscore character followed by the unique name of the data item. For example, the HGA boresight direction in the HGA frame is specified by: INS-76125_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. Structure Descriptions --------------------------------------------------------- TBD Mounting Alignment -------------------------------------------------------- Refer to the latest version of the MSL Frames Definition Kernel (FK) [3] for the MSL structures reference frame definitions and mounting alignment information. Antenna FOVs ---------------------------------------------------------- All antenna FOVs are defined as cones centered on the +Z axis of the corresponding antenna frames. The cone angular sizes are arbitrarily set to 10 degrees for HGA, 30 degrees for MGA, 90 degrees for LGAs, and 150 degrees for UHFs. \begindata INS-76060_FOV_FRAME = 'MSL_PLGA' INS-76060_FOV_SHAPE = 'CIRCLE' INS-76060_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76060_FOV_CLASS_SPEC = 'ANGLES' INS-76060_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76060_FOV_REF_ANGLE = ( 45.0 ) INS-76060_FOV_ANGLE_UNITS = 'DEGREES' INS-76061_FOV_FRAME = 'MSL_TLGA' INS-76061_FOV_SHAPE = 'CIRCLE' INS-76061_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76061_FOV_CLASS_SPEC = 'ANGLES' INS-76061_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76061_FOV_REF_ANGLE = ( 45.0 ) INS-76061_FOV_ANGLE_UNITS = 'DEGREES' INS-76062_FOV_FRAME = 'MSL_PUHF' INS-76062_FOV_SHAPE = 'CIRCLE' INS-76062_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76062_FOV_CLASS_SPEC = 'ANGLES' INS-76062_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76062_FOV_REF_ANGLE = ( 75.0 ) INS-76062_FOV_ANGLE_UNITS = 'DEGREES' INS-76063_FOV_FRAME = 'MSL_MGA' INS-76063_FOV_SHAPE = 'CIRCLE' INS-76063_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76063_FOV_CLASS_SPEC = 'ANGLES' INS-76063_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76063_FOV_REF_ANGLE = ( 15.0 ) INS-76063_FOV_ANGLE_UNITS = 'DEGREES' INS-76064_FOV_FRAME = 'MSL_DLGA' INS-76064_FOV_SHAPE = 'CIRCLE' INS-76064_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76064_FOV_CLASS_SPEC = 'ANGLES' INS-76064_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76064_FOV_REF_ANGLE = ( 45.0 ) INS-76064_FOV_ANGLE_UNITS = 'DEGREES' INS-76065_FOV_FRAME = 'MSL_DUHF' INS-76065_FOV_SHAPE = 'CIRCLE' INS-76065_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76065_FOV_CLASS_SPEC = 'ANGLES' INS-76065_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76065_FOV_REF_ANGLE = ( 75.0 ) INS-76065_FOV_ANGLE_UNITS = 'DEGREES' INS-76110_FOV_FRAME = 'MSL_RLGA' INS-76110_FOV_SHAPE = 'CIRCLE' INS-76110_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76110_FOV_CLASS_SPEC = 'ANGLES' INS-76110_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76110_FOV_REF_ANGLE = ( 45.0 ) INS-76110_FOV_ANGLE_UNITS = 'DEGREES' INS-76111_FOV_FRAME = 'MSL_RUHF' INS-76111_FOV_SHAPE = 'CIRCLE' INS-76111_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76111_FOV_CLASS_SPEC = 'ANGLES' INS-76111_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76111_FOV_REF_ANGLE = ( 75.0 ) INS-76111_FOV_ANGLE_UNITS = 'DEGREES' INS-76125_FOV_FRAME = 'MSL_HGA' INS-76125_FOV_SHAPE = 'CIRCLE' INS-76125_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76125_FOV_CLASS_SPEC = 'ANGLES' INS-76125_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76125_FOV_REF_ANGLE = ( 5.0 ) INS-76125_FOV_ANGLE_UNITS = 'DEGREES' INS-76126_FOV_FRAME = 'MSL_HGA_EB' INS-76126_FOV_SHAPE = 'CIRCLE' INS-76126_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-76126_FOV_CLASS_SPEC = 'ANGLES' INS-76126_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-76126_FOV_REF_ANGLE = ( 5.0 ) INS-76126_FOV_ANGLE_UNITS = 'DEGREES' \begintext End of the IK file.
