GOES-R(Geostationary Operational Environmental Satellite-R) Series

The GOES-R series of spacecraft, set to launch in 2015, is expected to double the clarity of today’s satellite imagery and provide at least 20 times more atmospheric observations from space. The next-generation GOES system will provide significantly improved image resolution and increase the rate of imagery coverage of earth surfaces from every 30 minutes to every 5 minutes and every 30 seconds for severe weather events. GOES-R advanced sensor technology will measure data such as solar activity, the charged particle environment, the Earth's magnetic field, temperature and moisture profiles, cloud properties, ozone estimates, and solar x-ray flux to support accurate weather forecasting, severe storm tracking, and meteorological research.

Advanced Baseline Imager (ABI): The Advanced Baseline Imager is the primary instrument on GOES-R for imaging Earth’s weather, climate, and environment. ABI will be able to view the Earth with 16 different spectral bands, including two visible channels, four near-infrared channels, and ten infrared channels. It will provide three times more spectral information, four times the spatial resolution, and more than five times faster coverage than the current system. Forecasters will be able to use the higher resolution images to track the development of storms in their early stages.

GOES-R Rebroadcast (GRB) is the primary space relay of Level 1b products and will replace the GOES VARiable (GVAR) service. GRB will provide full resolution, calibrated, navigated, near-real-time direct broadcast data. The content of the data distributed via GRB service will be the full set of Level 1b products from all instruments on board the GOES-R series spacecraft. This concept for GRB is based on analysis that a dual-pole circularly polarized L-band link of 12 MHz bandwidth may support up to a 31-megabits per second (Mbps) data rate – enough to include all ABI channels in a lossless compressed format as well as data from GLM, SUVI, EXIS, SEISS, and MAG.
