Atlas V • GOES-R

GOES-R (GOES-Geostationary Operational Environmental Satellites) satellite is a result of cooperation between NASA and National Oceanic and Atmospheric Administration (NOAA). It is part of large space system of weather forecasting, detection and observations of environmental anomalies and phenomena developed by NOAA since 1975. Satellite is manufactured by Lockheed Martin with utilization of A2100A bus. It will be long for 5.5 m with dry mass at 2800 kg and estimated operational life at 15 years. Gathered data will be downlinked with speed at 100 Mbps, transmitting will be performed on S band, L band and UHF channels. Satellite will be powered by two deployable solar arrays and onboard battery. They will provide up to 4 kW of power for following instruments: Advanced Baseline Imager (ABI - for gathering data on clouds and moisture in atmosphere), Space Environment In-Situ Suite (SEISS), Extreme Ultraviolet Sensor/X-Ray Sensor Irradiance Sensors (EXIS), Solar Ultraviolet Imager (SUVI), Geostationary Lightning Mapper (GLM), and Magnetometer (MAG). Propulsion of the spacecraft will be provided by LEROS-1C chemical rocket engines (thrust at 460 N) fueled with Hydrazine / MON and manufactured by British company Moog ISP. Satellite will be launched and put into GEO by Atlas V rocket in 541 configuration - with 5 m payload fairing, four additional boosters and Centaur upper stage powered with single 1 RL 10A-4-2 engine with thrust at 99.2 kN.
