NOAA publishes report on commercial GNSS-R ocean wind data pilot

NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) has released an executive summary report on its 2024-2025 Commercial Data Program pilot of commercial GNSS reflectometry (GNSS-R) data.

The pilot tested whether data from private providers could monitor ocean surface wind, a core NOAA mission need, at lower cost. It also looked at secondary uses, including soil moisture, flooding and sea ice characterisation. The work was carried out with partners such as the National Weather Service and included technical evaluation and analysis of the data.

NOAA reports that the pilot confirmed the commercial sector can reliably deliver GNSS-R observations across the agency. The Commercial Data Program assesses and buys space-based weather observations from industry to improve forecasts and meet requirements more efficiently. The report was announced on 22 October 2026.

Why it matters: Confirmation that commercial GNSS-R data are reliable supports wider use of this low-cost reflected-signal sensing for winds, soil moisture and flood mapping. Practitioners, including those in data-sparse regions, may gain more sources of such observations.
