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)

Visible & IR Imagery Lighting Mapping Space Weather Monitoring Solar Imaging

• Advanced Baseline Imager (ABI)

• Geostationary Lightning Mapper (GLM)

• Space Environment In-Situ Sensor Suite (SEISS)

• Magnetometer

• Solar Ultra-Violet Imager (SUVI)

• Extreme UV/X-Ray Irradiance Sensors (EXIS)

GOES-R is the next generation of NOAA geostationary satellites that will provide a major improvement in quality, quantity and timeliness of data collected.

Dimensions:• 5.4m from LV adapter to top of ABI• S/A Panels are approx. 1m x 4m each

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
