Voyager geometry, both Navigation and Pointing, information was produced by the Voyager Project at JPL and shipped on magnetic tape to the investigators. TAR files of those data tapes are available here but a Vax program to read them is not available at this time. Later, the Navigation and Ancillary Information Facilitory (NAIF) produced a few SPICE kernel files for the Mission and PPS instrument. See the NAIF web page at http://naif.jpl.nasa.gov for more information on using these files. Merged data and geometry can be found in the encounter directories.
