  1. SPICE Production at ESTEC April 2005

  2. Overview • SPK/CK production • SCLK production • FK and IKs production • Other Kernels SPICE Production at ESTEC

  3. SPICE Production at ESTEC Mirroring of ESTEC SPICE Kernels to NAIF FTP Server SPICE Toolkit JPL ESTEC FK & IK Support SPICE Support NAIF SOC FK & IK Support FK and IK Production FK and IK Generic Kernels FTP server LSK, PCK, etc. Mirroring of Generic SPICE Kernels SPICE Tools SPICE Kernels PI Teams FTP server ESOC SCI-SB Support Time Correlation Packets FD & FCT SCLK DDID DDS Request And Receive System Auxiliary Data Conversion System (ADCS) Orbit and Attitude File Spacecraft SPK and CK Solar Array Gimbals' Data Solar Array CK SPICE Kernel Delivery Notification SPICE Production at ESTEC

  4. SPK/CK production • Spacecraft SPK and CK files are created from ESOC/FD Orbit and Attitude files using ADCS: • Conversion is automated • ADCS also validates the conversion process. • ADCS converts only the format of the data, but the data themselves remain unchanged. • All ESA planetary missions’ SPKs and CKs are generated with the same system. • Solar Array CK files are produced from telemetry on request from the Teams (already foreseen production for Mars Express and SMART-1) • ESA Ground Stations SPK files will be produced in the near future. SPICE Production at ESTEC

  5. SCLK production • SCLK files are created from: • Time Correlation Coefficient Packets for Mars Express and Rosetta. • Time Correlation Packets for SMART-1 (not yet implemented) • Venus Express SCLK source TBC. • Fake SCLK files have been produced for SMART-1 and VEX and shall be used until a real SCLK file is provided (only for study purposes). • Special SCLK files might be required for SMART-1 instruments AMIE and SPEDE. SPICE Production at ESTEC

  6. FK and IK production • The Production of the Frames Kernels and Instrument Kernels for each mission is responsibility of the corresponding SOC. • Instrument Teams and NAIF support the SOCs in the production of the Frames Kernels and Instrument Kernels: SPICE Production at ESTEC

  7. Other kernels • All the other kernels that complete the Mars Express/Rosetta/SMART-1/Venus Express SPICE data set are obtained from NAIF, where they are produced. These kernels are: • SPKs: Planetary Ephemeris and DSN stations. • FK: DSN stations. • PCK: Planetary Constants. • Generic Text PCK for all bodies • High Precision Earth rotation binary PCK • Moon rotation binary PCK • Text PCKs for Rosetta targets • LSK: Leap-seconds and Time conversion constants. • Plate Model Kernels for asteroids and comet.

  8. SPICE Kernel Distribution • SPICE kernels are available in the ESTEC FTP server: MEX: ftp://gorilla.estec.esa.int/pub/projects/MEX/data/spice/kernels Rosetta: ftp://gorilla.estec.esa.int/pub/projects/rosetta/data/spice/kernels SMART-1: ftp://gorilla.estec.esa.int/pub/projects/Smart-1/data/spice/kernels VEX: ftp://gorilla.estec.esa.int/pub/projects/VEX/data/spice/kernels • SPICE kernels are also available in the NAIF FTP server for the following missions (ESTEC server is mirrored): MEX: ftp://naif.jpl.nasa.gov/pub/naif/MEX/kernels Rosetta: ftp://naif.jpl.nasa.gov/pub/naif/ROSETTA/kernels VEX: TBD SPICE Production at ESTEC

  9. SPICE and PDS/PSA Archive • SPICE Data Sets for all ESA planetary missions will be archived within the PSA using PDS Standards. • SPICE Data Sets will be accessible through the PSA web interface (www.rssd.esa.int/PSA). Additionally, the working repository will be kept available (see previous slide) • For archival purposes, filenames might be changed; nevertheless, information about the original filenames will be available for trace-back purposes. • SPICE to Archive Interface Control Documents will be available for all ESA missions and accessible through the PSA.
