3. Access

 

Programs Using the Interface Data

 

F&P PI software resident at the home institutions and the Data Management System CDFGEN (Common Data File Generation Program) shall access and process the F&P SEDR data from magnetic tape. Future plans call for the SEDR data resident at JPL to be distributed via electronic means to PI institutions over data or phone lines. For this capability, JPL software shall provide for the loading of SEDR data to a database with the distibution being accomplished either by JPL initiated transmissions or remote user access. In addition, the F&P SEDR may be accessed locally by the Low Rate Science Processor (LRSP) from the F&P SEDR database.

 

Synchronization Considerations

 

Timing and Sequencing Characteristics. All records in the F&P SEDR shall be ordered by ascending Spacecraft Event Time (SCET).

 

Input/Output Protocols, Calling Sequences

 

SEDR files shall be written to unlabelled magnetic tapes using binary write routines without any overhead. The format shall be as defined in this document.

QUICK FACTS

Manufacturer: The Galileo Spacecraft was manufactured by the Jet Propulsion Laboratory, Messerschmitt-Bölkow-Blohm, General Electric, and the Hughes Aircraft Company.

Mission Duration: Galileo was planned to have a mission duration of around 8 years, but was kept in operation for 13 years, 11 months, and 3 days, until it was destroyed in a controlled impact with Jupiter on September 21, 2003.

Destination: Galileo's destination was Jupiter and its moons, which it orbitted for 7 years, 9 months, and 13 days.
