============                                                                 
                                                                             
This document contains information pertaining to the SPICE ephemeris data    
submitted to the Planetary Data System (PDS) by NAIF, for  the Ulysses       
Trajectory Bundle. This bundle is organized into two collections, including: 
data and document. PDS4 documentation is in all XML. There is an XML label   
for every product in the archive.                                            
                                                                             
Ulysses Trajectory Data Collection                                           
==================================                                           
This data collection contains two versions of trajectory data. The first     
version contains position and attitude data provided by Ulysses MAG team.    
The second version was generated at the PDS/PPI node (UCLA) which includes   
trajectory data and spacecraft local time.                                   
                                                                             
                                                                             
This is a PDS4 archive of the following PDS3 data set:                       
ULY-J-EPHEM-6-SUMM-SYS3/ECL50-V1.0 (https://doi.org/10.17189/1519848).       
                                                                             
This volume was originally a part of the remake of the PDS volume ULY_5001   
that was produced for the ESA Special Publication 1230.                      
                                                                             
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 the network capabilities that allow archives to be        
distributed.  As a result, some of the documents and metadata 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stored in the PDS3 catalog files are no longer maintained locally, but are   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.                                                                   
                                                                             
Errata                                                                       
======                                                                       
There were no known deficiencies or errors reported in the errata.txt files  
under PDS3.                                                                  
                                                                             
During the migration from PDS3 to PDS4 no issues were found and corrected    
in the PDS4 metadata. The data remain unchanged.

This bundle was produced for the Planetary Data System (PDS) at the Planetary
Plasma Interactions (PPI) node.
