SPICE kernels for the ExoMars Rover and Surface Platform mission are not abailable yet.
EXOMARS 2016 SPICE KERNELS SET
The ESA SPICE Service (ESS), in collaboration the ExoMars2016 SGS and the Instrument Teams, produces a SPICE Kernel Dataset (SKD) for the ExoMars2016 mission. A complete description including naming convention and an index of the contents of the ExoMars2016 SKD can be found in the description of the ExoMars2016 repository.
The ExoMars2016 SPICE Kernels dataset consists of several SPICE kernels, organised as follows:
The SKD has the following directory structure:
- root directory (named after the mission: ExoMars2016)
- ck: Kernels that contain orientation for the spacecraft and some of its structures, (solar arrays, for instance).
- fk: Kernels that define reference frames needed for the Mission.
- ik: Kernels for the instruments on board the spacecraft.
- lsk: Leapseconds kernel.
- mk: Meta-kernel files (a.k.a "furnsh" files) that provide lists of kernels suitable for a given mission period in the appropiate order.
- pck: Kernels that define planetary constants.
- sclk: Spacecraft clock coefficients kernels.
- spk: Orbit kernels, for the spacecraft and other solar system bodies.
- dsk: Digital Shape kernels for extended bodies such as the TGO spacecraft
- release notes: Includes the Release Notes of the SKD.
- cosmo: The SPICE-enchanced configuration for the ExoMars2016 mission.
- other: different directories of interest.
OBTAINING THE KERNELS
The complete BepiColombo SPICE Kernel Dataset can be obtained from the ESA SPICE Service FTP.
In order to obtain the latest operational kernels we recommend you to download the kernels listed in the metakernel.
The latest version of the SKD's operational sub-set -including only the latest kernels listed on the metakernel- can be obtained either via:
- BitBucket Git Repository (Recommended Solution)
- Direct Download (Zip file with the latest version of the ExoMars2016 SKD in Git)
The Release notes of the latest version of the ExoMars2016 kernel collection can be seen here.
ORIGIN OF THE KERNELS
KERNELS CREATED BY THE ESA SPICE SERVICE
The ESA SPICE Service collaborates with the Instrument Teams to create instrument and frames kernels for ExoMars2016:
- Operational SPK, CK and SCLK kernels generated by the SPICE Operational Pipeline (ADCSng).
- RSSD frames kernel.
- The instrument kernels (IK) have been developed by the ESA SPICE Service and the Instrument Teams.
- The ExoMars2016 frames kernel has been created by the ESA SPICE Service.
GENERIC KERNELS PROVIDED BY NAIF
NAIF generates kernels that are mission independent. Some of them are used by ESA missions:
- Binary and text PCK and LSK kernels.
- Some SPK kernels with ephemeris of the Solar System bodies.
- SPK kernels for ground stations.
- Frames kernels for ground stations.
The WebGeocalc tool (WGC) provides a web-based graphical user interface to many of the observation geometry computations available from the SPICE system. A WGC user can perform SPICE computations without the need to write a program; the user need have only a computer with a standard web browse.
Access to the WebGeocalc here.
For more information on WeGeoCalc go to the NAIF WebGeocalc description.
