The GXS will be a hyperspectral infrared instrument that is planned to fly on the GeoXO program series of geostationary satellites. It will provide sounding observations of the western hemisphere for the first time, with critical information on the spatial and temporal gradients of atmospheric temperature and water vapor which will be fed into numerical weather prediction models run by National Weather Service and Oceanic and Atmospheric Research (OAR).

The contract scope includes the tasks and deliverables necessary to design, analyze, develop, fabricate, integrate, calibrate, test, verify, evaluate, support launch, supply and maintain the instrument Ground Support Equipment (GSE), and support Mission Operations at the NOAA Satellite Operations Facility (NSOF).

This competitive acquisition will result in a Cost-Plus-Award-Fee (CPAF) hardware contract, for the development of one (1) Flight Model (FM) FM1, two (2) options for the build of FM2 and FM3 and four (4) options for additional value to perform Engineering Studies, valued at $2M per option. The anticipated period of performance for this contract includes support for 10 years of on-orbit operations and 5 years of on-orbit storage, for a total of 15 years for each Flight Model (FM).

The North American Industry Classification System (NAICS) code for this acquisition is 541330 and the small business size standard is $25.5M. The anticipated contract award and effective date is late August 2023. The contract will be performed onsite at the Contractor's faclities, and onsite at GSFC and Kennedy Space Flight Center.
