GOES-R Overview 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 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 for forecasting and environmental analyses

Satellite Driving Requirements Provide precision, stable space platforms at two operational geostationary orbital locations (75W and 135W) 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 on- orbit 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 140Mbps (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 Spacecraft Configuration (External)

Notable Performance Elements Operates through daily station- keeping 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

Animation shows the vibration-isolation impact ABI and GLM are mounted on stiff optical bench –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 ABI & GLM Decoupled from Bus Design Elements Support Precision INR for Users Augmented attitude control array damping demonstrated with risk-reduction tests
