This SPK file contains the mission history trajectory for the
    Ulysses spacecraft (NAIF ID -55). It spans from 06-OCT-1990 19:05
    ET to 01-JAN-2050 12:00 ET. The predicted trajectory begins on
    30-JUN-2009.

    This file was created by converting NIO file pfile_ulysses_history.nio 
    provided by Mark Ryne, JPL NAV on October 20, 2010 to SPK format
    using NIOSPK utility program ver. 8.2.0.

    CAUTION: because of the way the source NIO file was created (by
    stitching together many individual orbit solutions) the trajectory
    in this SPK file has numerous discontinuities, in some cases,
    reaching a few hundreds or even thousands of kilometers.

    Contact NAIF (Chuck.Acton@jpl.nasa.gov or Boris.Semenov@jpl.nasa.gov)
    if you have any questions about this file.
