Abstract
AbstractThis paper describes a successfully functioning, commercial, off‐the‐shelf (COTS)‐based ground support system called the Integrated Monitoring, Analysis, and Control COTS System (IMACCS). IMACCS was implemented as a prototype by Goddard Space Flight Center (GSFC), Mission Operations and Data Systems Directorate (MO&DSD) to operate NASA's Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX). IMACCS was conceived specifically to build on previous experience in testbed evaluation of COTS products. The purpose of the IMACCS project was to integrate a typical set of such tools, connect them to live tracking and telemetry data from a real, on‐orbit satellite, and perform shadow mission operations. The objective of the IMACCS project was to assess the completeness, robustness, and performance of a COTS‐based ground system. As a constraint, IMACCS was to be implemented within 90 days of project approval. This paper discusses the challenges that led to the IMACCS project; the processes used for implementing IMACCS; how these processes fit within MO&DSD's reengineered ground systems development processes; and the results obtained by comparing IMACCS' requirements, operations, costs, and implementation process against the currently operating ground system.
