NASA, in coordination with the National Oceanic and Atmospheric Administration’s Geostationary Operational Environmental Satellites (GOES-R) Program, has selected Assurance Technology Corporation for a $101.7 million dollar contract.

The contract is for the Space Environment In-Situ Suite (SEISS), which will provide data for monitoring space environments as an instrument on the next generation of GOES.

The design and development of the SEISS instruments will be primarily performed at the contractor’s facility in Carlisle, Mass. Once launched, the SEISS suite will be used primarily by NOAA’s Space Environment Center in Boulder, Colo. The center provides real-time monitoring, forecasting and warnings of solar and geophysical events and disturbances.

The contractor will provide the SEISS suite of instruments and post-delivery support for the GOES-R series of weather satellites. The suite consists of three particle sensors: a magnetospheric particle sensor; solar and galactic proton sensor; and an energetic heavy ion sensor. The sensors will provide important information to warn of high-impact space storms and operational information on the radiation environment hazardous to humans in space, high-altitude aircraft, spacecraft electronics, solar power systems and radio communications.

GOES is funded, operated and managed by NOAA. NASA’s Goddard Space Flight Center, Greenbelt, Md., manages the acquisition of GOES-R instruments for NOAA. For NOAA information, contact John Leslie at: 301-713-1265 or visit:
