Customizing the JPL Multimission Ground Data System for Improved Productivity

Murphy, S.; Guerrero, A.; Louie, J.; Flora-Adams, D. (1994-11-14)

The Multimission Ground Data System was designed as a generic data system to meet the needs of multiple missions and avoid re-inventing capabilities for each new mission and thus reduce costs.
Customizing the JPL Multimission Ground Data System: Lessons Learned

Murphy, Susan C.; Louie, John J.; Guerrero, Ana Maria; Hurley, Daniel; Flora-Adams, Dana (1994-11-14)

This paper will describe lessons learned in adapting JPL's Multimission Ground Data System (MGDS) to fly the Voyager, Galileo, and Mars Observer missions. We will explain how powerful, existing ground data systems can be ...
Cuvettes and Flux Towers in the Sky

Cyber threat assessment of uplink and commanding system for mission operation

Ko, Adans Y.; Tan, Kymie M. C.; Cilloniz-Bicchi, Ferner; Faris, Grant (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2014, 2014-05-05)

Most of today's Mission Operations Systems (MOS) rely on Ground Data System (GDS) segment to mitigate cyber security risks. Unfortunately, IT security design is done separately from the design of GDS' mission operational ...
Cyber-attack methods, why they work on us, and what to do

Byrne, DJ (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2015, 2015-08-31)

Our team ran some methods against a selected set of projects within our organization to understand what the attacks do so that we can design and validate defenses against them.
