GOES N-P Spacecraft

GOES - NO/P is the next series of GOES satellites. The multimission GOES series N-P will be a vital contributor to weather, solar, and space operations and science. The National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) are actively engaged in a cooperative program to expand the existing GOES system with the launch of the GOES N-P satellites.

The Goddard Space Flight Center (GSFC) is responsible for procuring, developing, and testing the spacecraft, instruments and unique ground equipment. NOAA is responsible for overall program, funding, system in-orbit operation, and determining satellite replacement needs.

The GOES N-P series will aid activities ranging from severe storm warnings to resource management and advances in science. GOES N-P data will add to the global community of knowledge, embracing many civil and government environmental forecasting organizations that work to benefit people everywhere and help save lives.

GOES N-P represents the next generation of GOES satellites. A highly advanced attitude control system fosters enhanced instrument performance for improved weather service quality. NASA and NOAA have set a high standard of accuracy for GOES N-P, including data pixel location to two kilometers from geosynchronous orbit.

Some of the new top-level capabilities include:

  • A digital Low Rate Information Transmission (LRIT) formatted Weather Facsimile (WEFAX) service

  • Expanded measurements for the Space Environment Monitor (SEM) instruments

  • A new dedicated channel for the Emergency Managers Weather Information Network (EMWIN) service

  • A more stable platform for supporting improved Imager, Sounder, and SXI instruments

GOES-N, the first spacecraft in the new GOES-N/O/P series, lifted off aboard a Boeing Delta IV rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station, Fla. at 6:11 pm EDT on May 24, 2006.
