Given the cost-constrained nature of JPL Flight Projects, especially Discovery Class missions, there is more and more pressure to reduce the costs associated with mission operations, particularly the costs for the Ground Data System. This paper explores the successes (and failures) of using the Mission Management Office (MMO) GDS team to provide a common set of services, tools, procedures, and products to JPL Flight Projects.
This paper examines the requirements and the design considerations of the Synthetic Aperture Radar (SAR) ground data system for the Alaska SAR Facility (ASF) at the University of Alaska in Fairbanks (UAF) for the new era of Radarsat/ERS-2 missions. These include a new data acquisition planning capability to manage more satellites with global planning and to manage more than one instrument mode; a new archive strategy that is cheaper, faster, and better; a product generation system to produce data on demand and to produce data for the varied instruments and modes; and a product verification ability for the new and old products. In response to these new functional requirements, JPL is using a design approach that emphasizes an open systems, client/server architecture based on industry standards and commercial off-the-shelf technology.
