KPL/MK Meta-kernel for JUICE CReMA 4.2 N56 Pp5 Q19 ============================================================================ This meta-kernel lists the JUICE SPICE kernels providing information for the Baseline launch (141a) with GCO study option: - Altitude around 570 km The scenario is based on the following OEM files provided by Mission Analysis: JUICE_CReMA32d0_Baseline_0001.oem JUICE_CReMA4d1_Baseline_0001_GCO_N56_Pp5_Q19.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 juice_sc_sat_crema_4_1_gco_n56_pp5_q19_default_f20160326_v01.bc juice_sc_sat_crema_4_1_gco_n56_pp5_q19_comms_f20160326_v01.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. Finally please note that a GCO specific default attitude and comms profile has been added in order to accomodate the attitude for the period covered by JUICE_CReMA4d1_Baseline_0001_GCO_N56_Pp5_Q19.oem 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 ESAC 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 February 11, 2021 by Alfredo Escalante ESAC/ESA. \begindata PATH_VALUES = ( '../..' ) PATH_SYMBOLS = ( 'KERNELS' ) KERNELS_TO_LOAD = ( '$KERNELS/ck/juice_sc_sat_crema_3_2_default_20220601_20330625_f20160326_v04.bc' '$KERNELS/ck/juice_sc_sat_crema_4_2_comms_20291006_20330216_f20160326_v01.bc' '$KERNELS/ck/juice_sc_sat_crema_4_0_conjctn_20250923_20320105_f20160326_v01.bc' '$KERNELS/ck/juice_sc_sat_crema_4_0_flybys_20230530_20320917_f20160326_v03.bc' '$KERNELS/ck/juice_sc_sat_crema_4_2_N56_Pp5_Q19_default_f20160326_v01.bc' '$KERNELS/ck/juice_sc_sat_crema_4_2_N56_Pp5_Q19_comms_f20160326_v01.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_4_0_default_f20160326_v01.bc' '$KERNELS/fk/juice_v21.tf' '$KERNELS/fk/juice_sci_v08.tf' '$KERNELS/fk/juice_ops_v07.tf' '$KERNELS/fk/juice_dsk_surfaces_v03.tf' '$KERNELS/fk/juice_roi_v01.tf' '$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' '$KERNELS/ik/juice_janus_v06.ti' '$KERNELS/ik/juice_jmc_v01.ti' '$KERNELS/ik/juice_majis_v05.ti' '$KERNELS/ik/juice_navcam_v00.ti' '$KERNELS/ik/juice_pep_v09.ti' '$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' '$KERNELS/lsk/naif0012.tls' '$KERNELS/pck/pck00010.tpc' '$KERNELS/pck/de-403-masses.tpc' '$KERNELS/pck/gm_de431.tpc' '$KERNELS/pck/juice_jup006.tpc' '$KERNELS/pck/juice_roi_v00.tpc' '$KERNELS/sclk/juice_fict_20160326.tsc' '$KERNELS/spk/juice_struct_v10.bsp' '$KERNELS/spk/juice_cog_v00.bsp' '$KERNELS/spk/juice_roi_v01.bsp' '$KERNELS/spk/mar085_20200101_20400101.bsp' '$KERNELS/spk/earthstns_fx_050714.bsp' '$KERNELS/spk/estrack_v03.bsp' '$KERNELS/spk/jup310_20200101_20500101.bsp' '$KERNELS/spk/jup343_20200101_20500101.bsp' '$KERNELS/spk/de432s.bsp' '$KERNELS/spk/noe-5-2017-gal-a-reduced_20200101_20380902.bsp' '$KERNELS/spk/juice_mat_crema_3_2_20220601_20330626_v01.bsp' '$KERNELS/spk/juice_mat_crema_4_2_N56_Pp5_Q19_v01.bsp' '$KERNELS/dsk/juice_io_plasma_torus_v04.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 SPICE Kernel Dataset Version ------------------------------------------------------------------------ The SPICE Kernel Dataset version of the kernels present in this meta-kernel is provided by the following keyword (please note that this might not be the last version of the SPICE Kernel Dataset): \begindata SKD_VERSION = 'v280_20210211_001' \begintext Contact Information ------------------------------------------------------------------------ If you have any questions regarding this file contact the ESA SPICE Service (ESS) at ESAC: Alfredo Escalante Lopez (+34) 91-8131-429 spice@sciops.esa.int End of MK file.
