  1. Finding SPICE ComponentsAn Introduction tothe NAIF Server June 2004

  2. Overview • NAIF/SPICE “products” are available from the NAIF server • “Products” => kernels, software, documents • See next page for URLs • Access is via the ftp protocol • A web system will soon be available, making it easier to find what you want • Announcement will be made via “spice_announce” • Formally archived SPICE products from missions are also becoming available via the Planetary Data System (PDS) • http://pds.jpl.nasa.gov/ NAIF Server

  3. NAIF/SPICE URLs • SPICE tutorials • ftp://naif.jpl.nasa.gov/pub/naif/toolkit_docs/Tutorials/ • SPICE Toolkits for all supported environments • ftp://naif.jpl.nasa.gov/pub/naif/toolkit/ • Generic SPICE kernels (files not unique to a single mission) • ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/ • Mission-unique operations SPICE kernels (those that are available to NAIF) • ftp://naif.jpl.nasa.gov/pub/naif/<MISSION>/kernels/ • Mission-unique archived (or being archived) SPICE kernels • ftp://naif.jpl.nasa.gov/pub/naif/pds/ • SPICE announcements (by NAIF) • http://naif.jpl.nasa.gov/mailman/listinfo/spice_announce • SPICE discussion (by anyone) • http://naif.jpl.nasa.gov/mailman/listinfo/spice_discussion NAIF Server

  4. Looking for SPICE ProductsTop Level View Top level of useful info on the NAIF server Mission ops kernels Mission-independent kernels Formally archived kernels Toolkits and individual apps Toolkits docs in several formats Plus SPICE tutorials Additional apps not contained in the Toolkits NAIF Server

  5. Mission Ops Example - 1 ftp://naif.jpl.nasa.gov/pub/naif/CASSINI/kernels/ NAIF Server

  6. Mission Ops Example - 2 …/CASSINI/kernels/spk Kernel file Kernel file detached label (text) Kernel file naming conventions • • • aareadme.txt NAIF Server

  7. Generic Kernels Example - 1 ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/ NAIF Server

  8. Generic Kernels Example - 2 ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/spk/satellites/ “BRIEF” summary of all SPK files in the directory Typical SPK file Comments placed in the SPK file NAIF Server
