Abstract:

This paper focuses on studying a new method to evaluate the accuracy of satellite altimetry data which is determined on the different height at cross-over points between ascending and descending tracks. This method bases on the Gauss and Bexen methods. In this paper, we conducted the experiment by using 18676 observations of Cryosat-2 satellite from cycle 31 to cycle 43 in the sea area around the Truong Sa Archipelago. From these results, the authors proposed a new formula to evaluate the accuracy of satellite altimetry data in the case with and without systematic errors. The experimental results showed that, the altimetry data from Cryosat-2 on the sea around the Truong Sa Archipelago does not contain systematic error and obtains the accuracy at ± 0.035m.
