摘要
基于非洲东海岸MAYG站2020年年积日268~366的信噪比(SNR)数据开展GNSS-IR(global navigation satellite system interferometric reflectometry)监测海平面高度研究,并与Dzaoudzi验潮站的实测潮位进行对比。结果显示,BDS-GEO不适用于岸基测高;BDS-MEO的监测精度优于BDS-IGSO和GPS。
Based on the SNR(signal-to-noise ratio)data of doy 268-366 at the MAYG station on the east coast of Africa in 2020,we carry out the GNSS-IR(global navigation satellite system interferometric reflectometry)sea level monitoring study.We compare the results with the measured tide level of Dzaoudzi tide gauge station.The experimental results show that BDS-GEO is not suitable for shore-based altimetry.The monitoring accuracy of BDS-MEO is better than that of BDS-IGSO and GPS.
