Raytheon Company is a leader in environmental remote sensing, and is the prime contractor for the Joint Polar Satellite System’s (JPSS) Visible Infrared Imaging Radiometer Suite (VIIRS) instrument as well as the JPSS Common Ground System (JPSS CGS).
Raytheon's first VIIRS instrument is currently flying aboard the National Oceanic and Atmospheric Administration’s Suomi National Polar-orbiting Partnership (NPP) spacecraft and is slated for NOAA's four JPSS next-generation weather satellite program. Each JPSS satellite will cover the entire globe every 14 hours, giving users timely and up to date observations. As part of the U.S.'s polar satellite program, VIIRS represents the latest in a series of progressively capable technologies, and replaces and improves upon sensing technology that in some cases is 30 years old.
In addition to providing highly detailed information on emerging global weather patterns, VIIRS generates high-fidelity sea, land and atmospheric data for a variety of other applied products, including: monitoring of wildfires, drought, flooding, vegetation health, algal blooms, marine and airborne traffic, and nighttime phenomena.
The JPSS CGS is a flexible, cost-effective, global system designed to support current and future environmental sensing satellite missions. Since being deployed for the joint NOAA/NASA Suomi National Polar-orbiting Partnership (NPP) in 2011, the JPSS CGS has provided unprecedented global observation capabilities for multiple missions. JPSS CGS currently supports several domestic and international weather and environmental sensing satellite missions, including:
•JPSS (Suomi NPP, JPSS-1 through JPSS- 4)
•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)
Raytheon’s JPSS CGS provides the full common ground capability, from design and development through operations support and sustainment. JPSS CGS Block 2.0 benefits also include consolidated infrastructure for integration of multiple missions, reduced data latency for fresher observations, and a more flexible architecture that allows the system to protect individual missions while scaling to include new missions.
Ground terminals located near both poles decrease data latency by providing multiple sites for constellation data downlinks. Block 2.0 will allow the JPSS-1 satellite to downlink twice per orbit, once at the two polar receptors.
