KPL/MK Meta-kernel for CReMA Issue 3 Revision 1 Baseline Trajectory ========================================================================= 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. The kernels cover the following trajectory and attitude intervals for JUPITER ICY MOONS EXPLORER (-28): Start of Interval (ET) End of Interval (ET) ----------------------------- ----------------------------- 2022 MAY 31 23:59:59.999 2033 SEP 11 19:12:13.705 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_20220601_20330911_f20160326_vnn.bc juice_sc_sat_crema_x_y_comms_20220601_20330911_f20160326_vnn.bc juice_sc_sat_crema_x_y_flybys_20220601_20330911_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 he mission (interplanetary transfer with planetary swing-bys, 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. Finally the *_flybys_* kernel is loaded which includes the default s/c orientation for the moon flybys. Note that it is important to load this kernel after the *_comms_* one in order to prioritize the flyby attitude. 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 last updated on Nov 3, 2016 by Marc Costa Sitja ESAC/ESA.
