Sea Level Retrieval Using Multi-GNSS Multipath Reflectometry Based on Wavelet Analysis
Abstract Based on the wavelet analysis method, using the observation data of GPS, GLONASS, Galileo and Beidou, we select the better quality data to extract the instantaneous tide level through the quality analysis of different types of signal-to-noise ratio data. The experimental results show that the sea level retrieval using multi-GNSS multipath reflectometry based on wavelet analysis greatly improves the time resolution of tide level inversion results, and the accuracy is equivalent to LSP method, which can reach decimeter level.
Key words :
