<!--!introduction!--> Over the last few decades, sea level rise due to global warming has become a global issue, with polar and coastal regions being the most vulnerable. This study will focus on polar regions as they have a significant impact on the global climate and ecosystem. Sea level height is traditionally observed using in-situ tide gauges and satellite altimetry. However, both methods face challenges in polar regions. Tide gauges are difficult to set up and maintain, and satellite altimetry is limited by the design of its orbital inclination. To overcome these difficulties, Global Navigation Satellite System Reflectometry (GNSS-R) is adopted to monitor sea level and sea ice changes in polar regions. A sea ice detection algorithm will be developed to avoid the contamination for sea level measurements, and the impact of sea state bias error will also be taken into account to improve accuracy. On the other hand, this study will integrate multi-constellation and multi-frequency signal-to-noise ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
