KPL/MK Meta-kernel for CReMA Issue 3 Revision 1 SOC Studies - v260_20200720_001 ============================================================================ This meta-kernel lists the JUICE SPICE kernels providing information for the full mission based on the following mission scenario: mantra.jup_a5d_C141a_201603_r30_c7_LF_N45_hl5c_l2997_a5_p3_r74_r43_c5e.oem Usage of the Meta-kernel ------------------------------------------------------------------------- This metakernel is only for project analysis at this stage. Note that a default Attitude profile has been implemented for the whole mission by the following C-Kernels: juice_sc_sat_crema_x_y_default_YYMMDD_YYMMDD_f20160326_vnn.bc juice_sc_sat_crema_x_y_comms_YYMMDD_YYMMDD_f20160326_vnn.bc juice_sc_sat_crema_x_y_conjctn_YYMMDD_YYMMDD_f20160326_vnn.bc juice_sc_sat_crema_x_y_flybys_YYMMDD_YYMMDD_f20160326_vnn.bc Please note that the order in which the previous kernels is loaded is important. The *_default_* kernel implements the default attitude during the main phases of the mission (interplanetary transfer, Jupiter Tour and Ganymede Phase) this kernel needs to be loaded first and is followed by *_comms_* which provides a baseline of the communications attitude (required to perform an 8 hours daily pass with Malargue). If desired this kernel can be removed to omit this attitude. In order to generate this attitude, we consider JUICE to be visible from MALARGUE when JUICE has elevation above 10 degrees in the MALARGUE topocentric reference frame MALARGUE_TOPO. Next a CK implementing the Conjunction phases is set with a default conjunction orientation. Finally the *_flybys_* kernel is loaded which includes the default S/C orientation for the planetary swing-bys and moon fly-bys. In addition a default Solar Arrays orientation is implemented as follows: by default the Solar Arrays are in the power optimized direction except during pushbrooms around flybys CA when the solar panel in the S/C XY (panel surface normal aligned with +Z, wich is SADM=0). Reading the comments of the binary C-Kernels is very helpful to understand the implemented attitude. You can use the following NAIF command line utility to extract that information from the kernels: > commnt -r juice_sc_*.bc The kernels listed below can be obtained from the ESA SPICE Service FTP server: ftp://spiftp.esac.esa.int/data/SPICE/JUICE/kernels/ Implementation Notes ------------------------------------------------------------------------- IMPORTANT: this trajectory is designed using the latest Jupiter Moons ephemeris data as provided by the IMCCE - so called IMCCE L2 model It is recommended that users make a local copy of this file and modify the value of the PATH_VALUES keyword to point to the actual location of the JUICE SPICE data set's ``data'' directory on their system. Replacing ``/'' with ``\'' and converting line terminators to the format native to the user's system may also be required if this meta-kernel is to be used on a non-UNIX workstation. DISCLAIMER: Pleae note that the current kernels are pre-operational and they are subject to change. ------------------- This file was created on July 20, 2020 by Marc Costa Sitja ESAC/ESA. \begindata PATH_VALUES = ( '../..' ) PATH_SYMBOLS = ( 'KERNELS' ) KERNELS_TO_LOAD = ( '$KERNELS/ck/juice_sc_sat_crema_3_1_default_20220601_20330911_f20160326_v04.bc' '$KERNELS/ck/juice_sc_sat_crema_3_1_comms_20220601_20330911_f20160326_v03.bc' '$KERNELS/ck/juice_sc_sat_crema_3_1_conjctn_20220601_20330911_f20160326_v01.bc' '$KERNELS/ck/juice_sc_sat_crema_3_1_flybys_20220601_20330911_f20160326_v05.bc' '$KERNELS/ck/juice_lpbooms_f20160326_v01.bc' '$KERNELS/ck/juice_magboom_f20160326_v03.bc' '$KERNELS/ck/juice_mga_zero_f20160326_v02.bc' '$KERNELS/ck/juice_majis_scan_zero_f20160326_v02.bc' '$KERNELS/ck/juice_swi_scan_zero_f20160326_v02.bc' '$KERNELS/ck/juice_sa_crema_3_1_default_f20160326_v01.bc' '$KERNELS/fk/juice_v20.tf' '$KERNELS/fk/juice_sci_v07.tf' '$KERNELS/fk/juice_ops_v07.tf' '$KERNELS/fk/juice_dsk_surfaces_v02.tf' '$KERNELS/fk/juice_roi_v00.tf' '$KERNELS/fk/rssd0002.tf' '$KERNELS/fk/earth_topo_050714.tf' '$KERNELS/fk/earthfixediau.tf' '$KERNELS/fk/estrack_v03.tf' '$KERNELS/ik/juice_gala_v03.ti' '$KERNELS/ik/juice_janus_v05.ti' '$KERNELS/ik/juice_jmc_v01.ti' '$KERNELS/ik/juice_majis_v05.ti' '$KERNELS/ik/juice_navcam_v00.ti' '$KERNELS/ik/juice_pep_v08.ti' '$KERNELS/ik/juice_rime_v04.ti' '$KERNELS/ik/juice_rpwi_v02.ti' '$KERNELS/ik/juice_str_v00.ti' '$KERNELS/ik/juice_swi_v07.ti' '$KERNELS/ik/juice_uvs_v03.ti' '$KERNELS/lsk/naif0011.tls' '$KERNELS/pck/pck00010.tpc' '$KERNELS/pck/de-403-masses.tpc' '$KERNELS/pck/gm_de431.tpc' '$KERNELS/pck/juice_jup003.tpc' '$KERNELS/pck/juice_roi_v00.tpc' '$KERNELS/sclk/juice_fict_20160326.tsc' '$KERNELS/spk/juice_mat_crema_3_1_20220531_20330911_v01.bsp' '$KERNELS/spk/juice_struct_v09.bsp' '$KERNELS/spk/juice_cog_v00.bsp' '$KERNELS/spk/juice_roi_v00.bsp' '$KERNELS/spk/de430.bsp' '$KERNELS/spk/mar085_20200101_20400101.bsp' '$KERNELS/spk/earthstns_fx_050714.bsp' '$KERNELS/spk/estrack_v03.bsp' '$KERNELS/spk/jup300_20200101_20400101.bsp' '$KERNELS/spk/jup230_20200101_20400101.bsp' '$KERNELS/spk/jup310_20200101_20400101.bsp' '$KERNELS/spk/jup343_20200101_20400101.bsp' '$KERNELS/spk/noe-5-2010-gal-a2_20200101_20380902.bsp' '$KERNELS/dsk/juice_io_plasma_torus_v01.bds' '$KERNELS/dsk/juice_sc_bus_v03.bds' '$KERNELS/dsk/juice_sc_mag_v03.bds' '$KERNELS/dsk/juice_sc_mga_apm_v03.bds' '$KERNELS/dsk/juice_sc_mga_dish_v03.bds' '$KERNELS/dsk/juice_sc_sa+y_v03.bds' '$KERNELS/dsk/juice_sc_sa-y_v03.bds' ) \begintext End of MK file.
