Integrated GPS receiver for remote sensing sea state and land cover
Lie Chung Shen, Jhy Ching Juang, Ping Ya Ko, Ching Lang Tsai and Ching Liang Tseng

In this paper, a new application and the development of a highly integrated GPS receiver that uses reflected GPS signals for ground object detection and Digital Terrain Elevation DTED) mapping are described. First, both right-hand circular polarisation (RHCP) and left-hand circular polarisation (LHCP) antennas are employed so that direct and reflected signals can be acquired simultaneously. The direction of arrival of the signals may be along the reflected signal path or along the line of sight of a particular satellite. The aim of this study is to exploit the carrier phase, reflectivity of L1/L2 signal-to-noise density ratio components of the reflected signals, and direct signals for fresh stream water, ocean water, and ground object detection. The sea states are predicted by using the Doppler shifts resulting from the surface reflection from a moving surface. An integer ambiguity algorithm is also implemented. During the development and test stage, the DTED and satellite images are used and mapped using the integrated software.
