摘要：
The paper explored a method to obtain accurate lake surface heights using Global Navigation Satellite System (GNSS) Coarse/Acquisition Code (C/A) reflected from the ocean surface. The method is referred to as Global Navigation Satellite System-Rflection (GNSS-R) (C/A) code altimetry. It focuses on the extraction of the delay between the direct and reflected signal and inverting ocean altimetry with the delay and the geometric relationship. The ocean altimetry results are consistent with the height results of the differential positioning analysis of the data collected by a handheld GIS. The results show that we can achieve meter level height in seven minutes average.
