Modeling Additional Missions in the Joint Polar Satellite System (JPSS) Common Ground System (CGS)

The National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration (NASA) are jointly acquiring the next-generation civilian weather and environmental satellite system: the Joint Polar Satellite System (JPSS). The Joint Polar Satellite System will replace the afternoon orbit component and ground processing system of the current Polar-orbiting Operational Environmental Satellites (POES) managed by NOAA. The JPSS satellites will carry a suite of sensors designed to collect meteorological, oceanographic, climatological and geophysical observations of the Earth. The ground processing system for JPSS is known as the JPSS Common Ground System (JPSS CGS). Developed and maintained by Raytheon Intelligence, Information and Services (IIS), the CGS is a multi-mission enterprise system serving NOAA, NASA and their national and international partners. The CGS has demonstrated its scalability and flexibility to incorporate multiple missions efficiently and with minimal cost, schedule and risk, while strengthening global partnerships in weather and environmental monitoring.

Scalability to accommodate new missions in the future is a key requirement on the CGS, which has partially driven the upgraded Block 2.0 architecture currently being deployed into operations. This capability applies across three different types of support: managed missions, data processing missions and data acquisition and routing missions. This paper will describe how new missions can be added to the CGS, as well as how we model the associated impacts to system resources, capacity and performance.
