JUICE SPICE Kernel Dataset Release Notes v2.2.0 =========================================================================== This release notes file describes the status of the mission's SPICE Kernel Dataset for the given version. This version (2.2.0) provides a tag in the JUICE Git repository at the SOCCI Bitbucket: https://repos.cosmos.esa.int/socci/projects/SPICE_KERNELS/ Created by Marc Costa Sitja, ESAC/ESA, October 30, 2019. Notes -------------------------------------------------------- October 29, 2019 v2.2.0 - Generated default Solar Array attitude in accordance with SOC indications. Solar Arrays are power-optimised all times except for the Orbit Aligned attitude during Close Flybys when the arrays are at the XY plane (SADM=0) - Corrected JUICE COMMS attitude with downlink management during occultations; now downlink is not removed unless the occultation shortens it more than 3h 10min. - Corrected JUICE FLYBYS attitude with Hot/Cold attitude profiles (+Y S/C direction is inverted to keep the cold deck not illuminated). - Fixed interpolation error son trajectory for CrEMA 4.1 - Enhanced extended body modelling for S/C Bus and Solar Arrays. This has been used in the computation of the PEP NIM FoV obstruction. Issues fixed for this release -------------------------------------------------------- [SPICEPCR-358] - Solar Array Default attitude generation [SPICEPCR-355] - JUICE COMMS not present due to Occultation [SPICEPCR-232] - Generation of Kernels for CrEMA 4.1 (fixing interpolation errors) [SPICEPCR-304] - Re-generation of JUICE Flyby Default Attitude [SPICEPCR-261] - Re-generation of COMMS CK and inlcusion of criteria in various descriptions [SPICEPCR-192] - Include ESTRACK files in SKD Appendix: Release History =========================================================================== October 16, 2018 v2.1.0 - Updated center for the JUICE_SPACECRAFT frame for DSK to work - Added Solar Arrays Default Attitude. - Added Io Plasma Torus DSK generated by Rafael Andres (ESAC/ESA) and its corresponding SPK (embedded in the JUICE structures SPK). The Io Plasma Torus model is also available in Cosmographia. - Added an FK to define the DSK Surfaces. - Corrected PEP NIM description typos. October 10, 2018 v2.0.0 - This Kernel Dataset Release (SKD) is a milestone for the JUICE SPICE Kernel Dataset for it supports obtaining a subset of the SKD with Bit via Bitbucket. The SKD subset can also be obtained from a permanent link to a zipped file. - Generated scenarios for CReMA 4.0 Baseline and Backup solutions. - Corrected bug in Attitude for Fly-bys for the CReMA 3.0 and 3.1 scenarios. - Removed the Solar Conjunction default attitudes from the Default Attitude CK and generated a Superior Solar Conjunction only CK for CReMAs 3.0, 3.1, 3.2, 4.0, 4.0b those files are available in the MK. - Updated JUICE mission-specific Planetary Constants (juice_jup001.tpc) Added placeholder IDs, radii, prime meridian, pole and longitudinal axis for a series of small moons required by the JUICE SOC. - Added reduced versions of the planetary ephemeris to avoid oversizing of the SKD as much as possible. - Updated structures SPK to include MGA hinge and MGA Phase Center positions. The JUICE Center of Gravity information is now in a specific SPK. - The Cosmographia configuration files are now also available in the SKD. November 6, 2017 v1.6.0 Updated IK and FK due to updates in PEP NIM FOV and description. October 5, 2017 v1.5.2 Bug corrected in the the CKs that provide Default and Earth Communications attitude for the CReMA issue 3_2. Added jup300.bsp files that superseeds jup282.bsp for it includes the ephemeris of 55074, 55075 and 55076 bodies. July 19, 2017 v1.5.1 Bug corrected in the the CKs that provide default attitude for the full mission for all the CReMA issues: 3_0, 3_1 and 3_2. Added Solar Array default orientation as an auxiliary reference frame JUICE_SA_DEFAULT. June 14, 2017 v1.5.0 CReMa Issue 3 Revision 2 (3_2) Released with the corresponding SPK and CK files generated. Including updated ephemeris for Jovian Moons. The CKs that provide default attitude for the full mission have been updated for all the CReMA issues: 3_0, 3_1 and 3_2 with the following changes: - Implements Solar Conjunction Attitude for the Cruise phase and for the Jupiter Tour Phase. 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
