SPICE kernels contain critical information about the geometry,
pointing, and timing of NASA's spacecrafts.
For more information about SPICE visit the home page of PDS's
Navigation and Ancillary
Information Facility (NAIF).
Note that the primary source of SPICE data is NAIF's
anonymous FTP site.
See, in particular:
The SPICE Tabs
The tabs associated with this page describe the SPICE data files and
related information---how to obtain it and how to use it.
Ephemerides - SP kernels describing the
trajectory of the spacecraft and the motion of the planet and
satellites during each planetary encounter.
Pointing - C kernels and other pointing
information for Voyager's instruments.
Other - Other related kernels helpful
in the analysis of Voyager data.
