Abstract
Flight operations at the Jet Propulsion Laboratory (JPL) are now performed by teams of specialists, each team dedicated to a particular spacecraft. Certain members of each team are responsible for monitoring the performance of their respective spacecraft subsystems. Ground operations are manual, labor-intensive, and tedious. The challenge of the new decade is to operate a large number of spacecraft simultaneously, while sharing limited human and computer resources without compromising overall reliability. The Engineering Analysis Subsystem Environment (EASE) is being developed to enable fewer controllers to monitor and control power and other spacecraft engineering subsystems. An early version of the EASE prototype has been installed in the JPL Space Flight Operations Facility for on-line testing. This paper discusses the underlying concept, development, testing of the EASE prototype, and how it will aid in the ground operations of spacecraft power subsystems.
