The GOES-R spacecraft bus will be 3-axis stabilized and designed for 10 years of on-orbit operation preceded by up to 5 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)]
~5.5 meters (from launch vehicle interface to top of ABI)
Satellite (spacecraft and payloads) dry mass <2800kg
>4000W at end-of-life (includes accounting for limited array degradation)
System Module delivered to Lockheed Martin, Denver
Propulsion Core Module delivered to Lockheed Martin, Denver
System Module first power-on
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.
