KPL/MK Meta-kernel for JUICE Dataset v451 -- 150lb CReMA 5.1 Option B2 20240903_002 ============================================================================ This meta-kernel lists the JUICE 150lb CReMA 5.1 Option B2 SPICE kernels that provide information for the 150lb CReMA 5.1 Option B2 scenario. - Launch on April, 5th 2023 The kernels listed in this meta-kernel and the order in which they are listed are picked to provide the best data available and the most complete coverage for the JUICE 150lb CReMA 5.1 Option B2 scenario. Option B2: modifications from 5.1: higher inclination (33.1 to 38.0 degrees), 100 days more over 25 deg inclination, better resolution than A3 for Jupiter N/S high latitudes; improved high resolution and global coverage of Callisto. 150 days out of superior conjunction (instead of 136) during Ganymede orbit at 5000 km, 143 days out of superior conjunction (instead of 100) during Ganymede orbit at 500 km. The scenario is based on the following OEM file provided by Mission Analysis: JUICE_2024_Option_B2_acc.oem This meta-kernel was generated with the Auxiliary Data Conversion System version: ADCSng v4.2.8. Usage of the Meta-kernel --------------------------------------------------------------------------- This metakernel is only for science operations analysis at this stage. Note that a default Attitude profile has been implemented for the whole mission by the following C-Kernels: juice_sc_crema_5_1_150lb_23_1_b2_default_vnn.bc juice_sc_crema_5_1_150lb_23_1_b2_comms_vnn.bc juice_sc_crema_5_1_150lb_23_1_b2_conjctn_vnn.bc juice_sc_crema_5_1_150lb_23_1_b2_flybys_vnn.bc juice_sc_crema_5_1_150lb_23_1_b2_baseline_vnn.bc Please note that the order in which the previous kernels are 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. The *_baseline_* kernel provides the combined attitude from the other kernels and includes slews in between the different attitudes as generated by OSVE/AGM. This kernel, if present, has the higher priority and overwrites the S/C attitude provided by all the other kernels. 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 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. 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. The kernels listed below can be obtained from the ESA SPICE Web server: https://spiftp.esac.esa.int/data/SPICE/JUICE/kernels/ or from the ESA SPICE 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 DISCLAIMER: Please note that the current kernels are pre-operational and they are subject to change. 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. ------------------- This file was created on September 3, 2024 by Alfredo Escalante Lopez ESA/ESAC.
