On March 18, the National Geospatial-Intelligence Agency (NGA) posted a sources sought notice for the Satellite Altimetry Gravity Modeling Project. Responses are due by 10:00 a.m. Central on March 25.
NGA is a key member of the National System for Geospatial Intelligence (NSG) that supports U.S. strategic technology foundational to the Nation’s Department of Defense (DoD), Department of Homeland Security (DHS), and the Intelligence Community (IC). The scientific products the Agency is tasked to deliver provides a decisive advantage to policymakers, warfighters, intelligence professionals, humanitarian efforts, and first responders. NGA is the pre-eminent authority in geodetic sciences necessary for the development of timely, relevant, accurate and actionable Geospatial-Intelligence (GEOINT).
The Office of Geomatics (SFN) at NGA is required to collect and process various geosciences data and models into new geodetic models with geodetic error analysis support to a diverse group of military and civilian customers. For example, NGA creates the Earth Gravitational Model (EGM) for use in navigation products for the DoD and for general use by industry and academia. High resolution gravity maps are needed for SFN’s mission of Assured Positioning, Navigation, and Timing, especially regarding safety of navigation operations.
Recently, NGA conducted a review of the data, modeling, and techniques behind satellite altimetry models. This review showed improvements can be made to the geodetic and geophysical altimetry models by inclusion of new data sets and improved processing and modeling. NGA intends to update our EGM and other geodetic and geophysical products by incorporating new gravity models derived from the latest satellite altimetry data and techniques. NGA is seeking a vendor capable of reviewing current data and methodologies of satellite altimetry models, developing new gravity models derived from the latest satellite altimetry data and new techniques, and providing guidance and training for use by NGA.
