Joint Polar Satellite System Common Ground System

Multi-mission support for environmental missions

The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting satellites designed to monitor global environmental conditions and collect and disseminate data related to weather, atmosphere, oceans, land and near-space environment.

The JPSS Common Ground System (JPSS CGS)

The JPSS Common Ground System (CGS) is a flexible, cost-effective global system designed to support current and future weather and environmental sensing satellite missions. Since being deployed for NOAA's Suomi National Polar-orbiting Partnership (S-NPP) in 2011, the JPSS CGS has provided unprecedented global observation capabilities for multiple missions.


JPSS CGS, built as a flexible, cost-effective global common ground system, currently supports several domestic and international weather and environmental sensing satellite missions, including:

  • JPSS (Suomi NPP, JPSS-1, JPSS-2, Free Flyer)
  • NOAA's Polar-orbiting Operational Environmental Satellites (POES)
  • DoD's Defense Meteorological Satellite Program (DMSP)
  • JAXA's Global Change Observation Mission 1 (GCOM-W1)
  • EUMETSAT's Meteorological Satellite Program (MetOp)
  • National Science Foundation/United States Antarctic Program (NSF/USAP)
  • U.S. Navy Windsat/Coriolis
  • NASA Space Communications and Navigation (SCaN)

Designed to support future missions, the JPSS CGS is the most efficient and cost effective solution to improve global environmental observational capabilities.

Raytheon’s JPSS CGS provides the full common ground capability, from design and development through operations support and sustainment.

The JPSS Program

Developed by the National Aeronautics and Space Administration (NASA) for the National Oceanic and Atmospheric Administration (NOAA), the JPSS program will integrate future civilian and military polar-orbiting environmental satellite space and ground segments with a single ground system. This new system represents a major upgrade to the existing Polar-orbiting Operational Environmental Satellites (POES), which have successfully served the operational weather forecasting community for nearly 50 years.

JPSS Concept of OperationsThe JPSS Concept of Operations

Operated by NOAA, JPSS is an “end-to-end” system that includes sensors; spacecraft; command, control and communications; data routing; ground based processing and dissemination of weather data to users around the globe, such as NOAA’s National Weather Service and the National Hurricane Center.

JPSS polar orbiters will carry a complement of advanced imaging and sounding sensors, which will increase NOAA and DoD capabilities to monitor the entire planet and produce weather and climate predictions at a much higher fidelity and frequency. These advanced capabilities will enable NOAA to better fulfill its mission to protect lives and property by increasing the timeliness and accuracy of public warnings and forecasts of weather and climate events.

JPSS CGS Delivers Crucial Data for National Weather Forecasts

Raytheon brings more than four decades of high-availability, reliable, precision-based, command-and-control systems experience to S-NPP and future JPSS missions. S-NPP is the bridge between existing polar-orbiting satellites and the launch of JPSS-1, scheduled for 2017. Providing critical data for Earth observation, S-NPP data is used to generate environmental data products, such as measurements of clouds, vegetation, ocean color and land and sea surface temperatures — all significant inputs to improve weather forecasting capabilities.

While S-NPP and JPSS will not prevent severe weather events such as hurricanes, tornadoes or blizzards from occurring, Raytheon’s advanced technologies enable meteorologists and forecasters to make more timely and accurate weather predictions that support NOAA’s “Weather Ready Nation” campaign and help save lives, protect property and decrease the devastating economic impacts caused by severe weather.
