Geostationary Operational Environmental Satellite R-Series (GOES-R)
For decades, NOAA’s Geostationary Operational Environmental Satellite (GOES) spacecraft have delivered reliable weather forecasts, helping people work and travel under stormy skies with confidence. Data from the GOES satellites provide short-term advance weather warning products to the commercial, educational, and public sectors to protect lives, property and the environment, and to foster economic growth and promote educational research.
The next-generation of these geostationary satellites called GOES-R will improve weather forecasting quality and timeliness generating significant economic benefits to the nation in the areas of climate monitoring, ecosystems management, commerce and transportation.
Lockheed Martin designed and is building all four of the nation’s new GOES-R Series weather satellites (R, S, T and U). The first, GOES-R, is scheduled to launch Nov. 4, 2016.
The GOES-R satellites are based on Lockheed Martin’s famed A2100 bus which has seen hundreds of years of combined on-orbit operations. The 6,280-pound (2,850-kg), three-axis stabilized spacecraft was designed for an on-orbit life of 15 years. Stability of the satellite and its sensors was critical in the design of the system.
Lockheed Martin has a more than 50-year history of designing and building weather and environmental spacecraft and instruments dating back to TIROS 1 in 1960, the world’s first weather satellite. The company has built and launched just over 100 weather and environmental spacecraft for our government’s civil and military agencies.
The GOES-R satellite will carry six instruments that fit into three classifications: Earth-pointing, solar-pointing and in-situ (near environment). Lockheed Martin is providing three of the instruments for each the satellites; the Solar Ultraviolet Imager (SUVI), the Geostationary Lightning Mapper (GLM) and the magnetometer.
SUVI will observe the sun in extreme ultraviolet wavelength range, providing full-disk solar images with increased resolution, sensitivity and dynamic range over current capabilities.
GLM is an innovative instrument that maps lightning across the U.S. in real time. It will take hundreds of images every second in near-infrared, mapping both cloud-to-cloud and cloud-to-ground lightning. Research shows that increased lightning rates can be a predictor of looming severe weather, and GLM could increase lead times for severe storm and tornado warnings.
The magnetometer measures the space environment magnetic field that controls charged particle dynamics in the outer region of the Earth’s magnetosphere. These solar charged particles can be dangerous to spacecraft and human spaceflight.
- GOES-R satellites will be in a geostationary orbit 22,500 miles above the Earth, always looking down and monitoring the U.S. and western hemisphere.
- GOES-R will transmit more data in the first six months of operation than all previous GOES weather satellites combined.
- The Geostationary Lightning Mapper will be the first operational lightning mapper flown in geostationary orbit.
- GOES-R will continue its important role in the Search and Rescue Satellite-Aided Tracking (SARSAT) system which has contributed to the rescue of thousands of individuals in distress.
