Multimission ground data system support of NASA'S planetary program

Abstract

NASA funds the Multimission Operations Systems Office (MOSO) at the Jet Propulsion Laboratory to design, develop, and operate the Advanced Multimission Operations (AMMOS) multimission ground data system capabilities that are used to control operational spacecraft and process data returned from a variety of planetary missions. The AMMOS design is based on use of modular, networked capabilities and industry standard hardware and software. Individual missions adapt multimission tools and services to support ground data processing during spacecraft development and operations. Utilization of a multimission core capability significantly reduces the cost of development and operation of ground data systems for each individual project. This paper describes the AMMOS system, and the general purpose set of AMMOS multimission capabilities, services and tools that are used to support the NASA planetary program. These capabilities include mission planning and analysis tools, sequence generation tools, command processing, ephemeris generation and optical navigation capabilities, real time engineering and science data processing, monitor and display functions, spacecraft analysis systems, science instrument data processing and photoproduct generation capabilities, data acquisition and distribution services, and tools for production of archival science data records. The system is used to support multiple missions that are operating simultaneously.
