About this opportunity
The National Geospatial-Intelligence Agency (NGA) is soliciting proposals for the development of a comprehensive altimetry-based data and error model covering all global oceans, integrating satellite data from multiple missions including NASA's SWOT, Jason, Sentinel, and CryoSat systems. The contractor will be required to provide technical support for gravimetric modeling, data generation, and employee training to NGA geodesists, with deliverables including global altimetry models in plain text format containing latitude, longitude, elevation, and gravity values. Proposals must demonstrate technical capability in satellite altimetry and gravity field determination methods, with evaluation conducted using the lowest price technically acceptable methodology across three factors: Technical Approach, Price, and Past Performance. Offerors must submit their proposals electronically in three separate volumes, with the technical volume limited to five pages and past performance documentation for up to three relevant contracts completed within the last three years. The proposal submission deadline is June 23, 2025, with contract award anticipated to a single contractor.
This solicitation operates under NAICS code 541360 (Geophysical Surveying and Mapping Services) with a small business size standard of $28.5 million, though no set-aside designation has been applied to this opportunity. The contract structure includes a firm-fixed-price base period with four potential option years, creating a total five-year period of performance for the satellite altimetry gravity modeling project. Key deliverables must cover satellite data from 80° South to 88° North latitude, with the contractor required to conduct monthly progress updates and provide annual training sessions for two NGA geodesists throughout the contract duration. Work performance will be unclassified and validation must be conducted against open-source marine gravity data from institutions including NOAA, USGS, and Woods Hole Oceanographic Institution. The primary place of performance is Arnold, Missouri 63010, where deliveries will be made to NGA's Office of Geomatics facility.
