GOES-R Spacecraft Overview

The GOES-R spacecraft bus will be three-axis stabilized and designed for 10 years of on-orbit operation preceded by up to five years of on-orbit storage. The satellite will be able to operate through periodic station-keeping and momentum adjust maneuvers, which will allow for near-continuous instrument observations. Other notable performance elements include: vibration isolation for the Earth-pointed optical bench and high-speed spacecraft-to-instrument interfaces designed to maximize science data collection. The cumulative time that GOES-R science data collection (including imaging) will be interrupted due to all momentum management, station-keeping, and yaw flip maneuvers will be under 120 minutes/year. This is a nearly two orders of magnitude improvement compared to the current GOES satellites. The spacecraft will carry three classifications of instruments: nadir-pointing, solar-pointing, and in-situ.
The satellite driving requirements are:
- Spacecraft on-orbit life of 15 years with orbit East-West and North-South position maintained to within +/-0.1 degree
- Collect and transmit up to 100Mbps instrument payload data from each location continuously
- Continuous rebroadcast function at L-Band up to 31 Mbps utilizing dual polarization
- Provide continuing services [Search and Rescue, Data System Collection, Emergency Manager’s Weather Information Network (EMWIN)]
- February 2016: Testing underway in preparation for launch in October 2016
- January 2015: All GOES-R instruments integrated with the spacecraft
- September 2014: System Module and Core Module successfully mated
- April 2014: System Module delivered to Lockheed Martin, Denver
- March 2014: Propulsion Core Module delivered to Lockheed Martin, Denver
3D Model of the Spacecraft
GOES-R will offer advanced imaging for more accurate forecasts, real-time mapping of lightning activity, and improved monitoring of solar activity. It will improve support for the detection and observations of meteorological phenomena that directly affect public safety, protection of property, and ultimately, economic health and development.
