Voyager 1 Saturn POS Ephemeris Kronographic (L1) Coords Browse |
Data Bundle Readme
This document contains information pertaining to the Voyager 1 Saturn POS
Ephemeris Kronographic (L1) Coords Browse Data Bundle, which contains
Voyager 1 Saturn encounter ephemeris data in Kronographic (L1) coordinates
covering the period 1980-11-10 to 1980-11-18. Two versions, both covering the
same time period, but containing slightly different data, are provided. One
version was generated by the Voyager MAG team from Voyager SEDR, the other by
the PDS/PPI node using the VG1_SAT.TSP and PCK00006.TPC SPICE kernels. Due to
inaccuracies in Voyager SEDR, as well as changes in the values of some key
parameters (e.g. Saturnian radius) the timing is improved for the SPICE
generated data. However, since much of the original analysis was based
upon the SEDR generated ephemeris, this data has been included as well.
(Note: The VG1_SAT.TSP and PCK00006.TPC SPICE kernels are not currently
archived in PDS, but they are available from NASA's Navigation and Ancillary
Information Facility (NAIF), https://naif.jpl.nasa.gov/naif/index.html)
This bundle is organized into several collections, including
data-sedr, data-spice and document. PDS4 documentation is all XML. There is
an XML label for every product in the archive.
Every effort has been made to insure that the data are of the best quality
available. However, users are encouraged to verify the correctness of the
data prior to submitting any publications or other work based on these
data and report any issues to PDS/PPI.
This is a PDS4 archive of the following PDS data set:
that was originally archived under PDS3 in the VG_1601 volume.
Under the PDS3 standard all archives were self contained and could in
principle be stored in a single file system (disk, CD-ROM, etc.). PDS4 takes
advantage of network capabilities that allow archives to be
distributed. As a result, some of the documents and meta data previously
stored in the PDS3 catalog files are no longer maintained locally, but are
maintained in a central repository. Those files are referenced by unique PDS
logical identifiers that are included in the document collection inventory.
