Abstract

The NOAA-NASA jointly-acquired Joint Polar Satellite System (JPSS) will replace the afternoon orbit component and ground processing system of the current Polar-orbiting Operational Environmental Satellites (POES). The ground system, known as the ‘Common Ground System (CGS)’, and developed by Raytheon Intelligence, Information and Services (IIS) provides command, control, and communications (C3) and data processing and product delivery. The CGS currently flies the Suomi NPP satellite and routes mission data to U.S. ground facilities, where it processes the data into mission products and provides them to US weather centrals. The CGS also supports various levels of data acquisition, routing and processing for multiple other missions across the globe today, with plans for incorporation of more missions in the future. This paper describes the CGS and the multi-mission-driven architectural tenets that are guiding its next round of technological upgrades in late 2015.
