For the Jupiter Tour Phase, -X (HGA) points to Earth and +Y to the normal of the Jupiter Mean Equator plane. - The Planetarty swing-bys have been moved to the Flyby Attitude CK. The Fly-by Attitude CK now includes the Planetay swing-bys. April 3, 2017 v1.4.1 Created SOC Operational Scenario that includes the studies of the GCO500 and the Europa Flyby scenario generated for Project and Industry. Theses scenarios are included in a new metakernel: juice_crema_3_1_soc_ops_study_v141.tm This scenario has been added to te WebGeocalc instance and to the SPICE-Enhanced Cosmographia Configuration. Added CKs delviered by SOC that correspond to the operational studies. Added SPK for New Norcia as requested by Nicolas Altobelli. February 13, 2017 v1.4.0 Added JUICE__RAM frame definitions as requested by Christian Erd. Added diagram for the PEP Nadir Unit frames definition. Added PEP NIM Thermal and Neutral/ion references, corrected PEP JNA reference frame. Added JUICE__RAM frames references. The full list of PEP IDs is now included in the PEP IK (from version 05) and only a reference is provided in this FK. This has been done in order to avoid overloading of this FK. As indicated by Gabriella Stenberg Weiser: updated JDC and JNA Sector definitions and added FOV for JDC pixels and JNA sectors. Updated NIM FOV definitions by adding the NIM neutral/ion mode and the thermal mode FOVs as indicated by Andre Galli. In order to facilitate a more one-to-one correspondance with SPICE Archives, following the advice from NAIF and in order to improve and make the meta-kernel management easier: earlier versions of files which have or have not been included in a meta-kernel will NOT be moved to the former_versions directory in the FTP as they used to. Instead all files will be kept in the directory and file management will be done solely via the meta-kernel. This change is applied retroactively. This does not apply to the meta-kernel directory. December 5, 2016 v1.3.1 Added jup310.bsp Jupiter System ephemeris in order to include Adrastea and Metis data as requested by Thomas Roatsch. Updated SWI frame definitions and added Channel 1 and Channel 2 FOVs. October 25, 2016 v1.3.0 The SWI and PEP Instrument kernel have been updated. More concretely for PEP the Field-of-views for JENI and NIM have been corrected. Consequently the JUICE frames kernel has been updated. Frames and instrument kernels for the Medium Gain Antenna, Star Trackers, JUICE Monitoring Cameras and NavCams have been generated. Updated the definition of the Solar Array Frames. Downgraded the epehemeris used for non-Jovian Solar System bodies from de423.bsp to de430.bsp in order to be aligned with the trajectories provided by Arnaud Boutonnet from MAn (Arnaud.Boutonnet@esa.int). October 7, 2016 v1.2.0 The names for the Meta-kernels, C-kernels and SP-kernels has been updated as agreed with Project and Mission Analysis. They now refer to CReMa releases. Default orientation for the CReMa Issue 3 Revision 1 has been corrected. SWI Instrument kernel has been updated. September 29, 2016 v1.1.0 Default orientation for the 141a Consolidated Trajectory has been updated for the transitions from Hot to Cold -and viceversa- transfer periods were wrong. Added default orientation for the c141_n45 trajectory. Which is consolidated as per the latest CReMA report: JUICE - Jupiter Icy moons Explorer Consolidated Report on Mission Analysis (CReMA), Issue 3, Revision 1. Updated Meta-Kernel name convention and version number -they match the Kernel Dataset version now, as consolidated with ExoMars 2016 Kernel Dataset-. August 19, 2016 v1.0.0 First release of the JUICE Pre-Operational Kernel dataset. The dataset includes the initial draft version of the kernels by ODC Space which were reviewed and updated by the ESA SPICE Service. The main focus of these kernels is to support the studies of the 141 Consolidated Trajectory and to support the studies of the JUICE WG3. End of aareadme.txt
