KPL/FK Juventas Spacecraft Frames Kernel ============================================================================= This frame kernel contains complete set of frame definitions for Juventas, including definitions for the Juventas fixed and Juventas science instrument frames. This kernel also contains NAIF ID/name mapping for the Juventas science instruments and s/c structures (see the last section of the file). Version and Date ----------------------------------------------------------------------------- Version 0.2 -- August 25, 2023 -- Rafael Andres Blasco, ESAC/ESA Added STR reference frames and NAIF ID/body definitions. Version 0.1 -- May 5, 2023 -- Alfredo Escalante Lopez, ESAC/ESA Added JURA, GRASS, NAVCAM and LIDAR reference frames and NAIF ID/body definitions. Corrected JUVENTAS diagrams and Y axis alignment. Version 0.0 -- June 20, 2022 -- Alfredo Escalante Lopez, ESAC/ESA Preliminary Version. Only basic ID and frame definitions.

Loading the kernel associates the data items with their names in a data structure called the "kernel pool". The SPICELIB routine FURNSH loads a kernel into the pool as shown below: FORTRAN: (SPICELIB) CALL FURNSH ( frame_kernel_name ) C: (CSPICE) furnsh_c ( frame_kernel_name ); IDL: (ICY) cspice_furnsh, frame_kernel_name MATLAB: (MICE) cspice_furnsh ( 'frame_kernel_name' ) PYTHON: (SPICEYPY)* furnsh( frame_kernel_name ) In order for a program or routine to extract data from the pool, the SPICELIB routines GDPOOL, GIPOOL, and GCPOOL are used. See [2] for more details. This file was created and may be updated with a text editor or word processor. * SPICEYPY is a non-official, community developed Python wrapper for the NAIF SPICE toolkit. Its development is managed on Github. It is available at: https://github.com/AndrewAnnex/SpiceyPy Juventas Mission NAIF ID Codes ----------------------------------------------------------------------------- The following names and NAIF ID codes are assigned to the Juventas spacecraft, its structures and science instruments (the keywords implementing these definitions are located in the section "Juventas Mission NAIF ID Codes -- Definition Section" at the end of this file): Juventas Spacecraft and Spacecraft Structures names/IDs: JUVENTAS -15513 JUVENTAS_SPACECRAFT -15513000 (synonym: JUVENTAS_SC) Juventas JURA IDs: JUVENTAS_JURA -15513110 JUVENTAS_JURA+X -15513111 JUVENTAS_JURA-X -15513112 JUVENTAS_JURA+Y -15513113 JUVENTAS_JURA-Y -15513114 Juventas GRASS IDs: JUVENTAS_GRASS+X -15513210 JUVENTAS_GRASS+Z -15513220 Juventas NAVCAM IDs: JUVENTAS_NAVCAM -15513310 Juventas LIDAR IDs: JUVENTAS_LIDAR -15513410 Juventas STR IDs: JUVENTAS_STR-1 -15513510 JUVENTAS_STR-2 -15513520 Juventas Mission Frames ----------------------------------------------------------------------------- The following Juventas frames are defined in this kernel file: Name Relative to Type NAIF ID ====================== ======================== ========== ========= Spacecraft frames: ------------------- JUVENTAS_SPACECRAFT J2000 DYNAMIC -15513000 JURA frames: ------------ JUVENTAS_JURA JUVENTAS_SPACECRAFT FIXED -15513110 JUVENTAS_JURA+X JUVENTAS_SPACECRAFT FIXED -15513111 JUVENTAS_JURA-X JUVENTAS_SPACECRAFT FIXED -15513112 JUVENTAS_JURA+Y JUVENTAS_SPACECRAFT FIXED -15513113 JUVENTAS_JURA-Y JUVENTAS_SPACECRAFT FIXED -15513114 GRASS frames: ------------- JUVENTAS_GRASS+X JUVENTAS_SPACECRAFT FIXED -15513210 JUVENTAS_GRASS+Z JUVENTAS_SPACECRAFT FIXED -15513220 NAVCAM frames: -------------- JUVENTAS_NAVCAM JUVENTAS_SPACECRAFT FIXED -15513310 LIDAR frames: ------------- JUVENTAS_LIDAR JUVENTAS_SPACECRAFT FIXED -15513410 STR frames: ------------- JUVENTAS_STR-1 JUVENTAS_SPACECRAFT FIXED -15513510 JUVENTAS_STR-2 JUVENTAS_SPACECRAFT FIXED -15513520 Juventas Frames Hierarchy ----------------------------------------------------------------------------- The diagram below shows the Juventas spacecraft and its structures frame hierarchy (not including science instrument frames.)
