Sea ice thickness, one of the most critical sea ice parameters, has long lacked extensive spatial coverage and timely monitoring techniques. In this study, we develop a method that can provide daily first-year ice thickness retrieval by coupling a microwave reflection model with a thermodynamic model using Global Navigation Satellite System-Reflectometry (GNSS-R) data from China's Tianmu-1 constellation (22 satellites). Sea ice thickness estimated from Tianmu-1 shows strong agreement with the merged CS2SMOS (CryoSat-2 and SMOS) product, demonstrating a correlation coefficient of 0.80 and a root mean square deviation of 0.26 m. The Tianmu-1 constellation achieves daily first-year sea ice thickness measurements at 25 km resolution in the Arctic Ocean, and can provide robust support for navigation in the North-East Passage.
