GOES-R Overview Extending the continuity of NOAA’s 40 -year geostationary mission, GOES-R will be the next weather sentinel for monitoring threatening weather, and providing data forecasting and environmental analyses • A collaborative development and acquisition – Flight Project - led by NASA – Ground Segment Project - led by NOAA • Scheduled for launch in 2015 • Six advanced instruments • New and improved capabilities for – decreased lead times for severe weather warnings – better storm tracking capabilities – solar, space weather, and climate analyses – advanced products for aviation, transportation, commerce

Satellite Driving Requirements • Provide precision, stable space platforms at two operational geostationary orbital locations (75 W and 135 W) carrying the baseline instrument set • Operational Mission - First Launch 2015: Provide continuity and improvements over the current system with spacecraft bus reliability of 0. 81 after 10 years of on-orbit operation preceded by 5 years ground storage & up to 5 years onorbit storage • Spacecraft On-Orbit Life of 15 years with orbit East-West and North-South position maintained to within +/-0. 1 degree. Support 9 station location changes • Collect and transmit up to 140 Mbps (coded) Instrument Payload data from each location continuously. • Continue Rebroadcast function at L-Band up to 31 Mbps utilizing dual polarization • Provide continuing and new services (Search & Rescue, Data Collection, EMWIN)

GOES-R Mission GOES-R is the next generation of NOAA geostationary satellites that will provide a major improvement in quality, quantity and timeliness of data collected. Visible & IR Imagery • Advanced Baseline Imager (ABI) Lighting Mapping • Geostationary Lightning Mapper (GLM) Space Weather Monitoring • Space Environment In-Situ Sensor Suite (SEISS) • Magnetometer Solar Imaging • Solar Ultra-Violet Imager (SUVI) • Extreme UV/X-Ray Irradiance Sensors (EXIS)

Notable Performance Elements • Operates through daily stationkeeping and momentum adjust maneuvers – Low risk station-keeping operations – Increased instrument availability – Decreased propellant required due to high efficiency thruster • Yaw flip improves ABI radiometric response – Outage twice per year – Total time of noncompliance for instrument interface requirements <120 min per year • Vibration Isolation for optical bench

Design Elements Support Precision INR for Users • ABI and GLM are mounted on stiff optical bench ABI & GLM Decoupled from Bus – Dynamics are tunable to optimize system performance – Couple instrument motion to IMU and star trackers with low thermal distortion • High-accuracy attitude determination system on the instrument optical bench – High accuracy star trackers – High-bandwidth, low-latency and low-noise IMU for effective motion compensation Animation shows the vibration-isolation impact Augmented attitude control array damping demonstrated with risk-reduction tests
