Meta-kernel for JUICE CReMA 3.0
============================================================================
This meta-kernel lists the JUICE SPICE kernels providing information
for the Baseline launch (141a). The main updates are:
- Baseline for industrial contract
- Ganymede prograde orbit
The scenario is based on the following OEM file provided by Mission
Analysis:
mantra_juice_jup_a5d_141a_lau_c5e_016.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

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: Please note that the current kernels are pre-operational and
they are subject to change.
