ESA-backed study uses Spire GNSS-R data to map Arctic-wide sea ice freeboard

ESA-supported researchers led by the Technical University of Munich (DGFI-TUM) and the Norwegian Research Centre used Spire Global’s GNSS-Reflectometry satellite data to generate Arctic-wide sea ice freeboard maps across an entire winter season. The study found strong agreement with established altimetry datasets, including ESA’s CryoSat mission, supporting the use of commercial RF sensing data alongside government satellites for all-weather, day-night monitoring. Spire said the new research has already generated these results, and no future presentation was specified.
