Abstract

In this paper, the gain and gain pattern of GPS receiver’s antenna and the carrier-to-noise ratio of received signal are described. The concept of C/N 0 pattern is introduced. The relationship between the C/N 0 pattern and gain pattern is derived. The time variation and direction variation of atmospheric loss were determined initially. The concept of C/N 0 anomaly and the C/N 0 anomaly pattern were introduced. It would be shown that the orientation of passive interference could be determined with the C/N 0 anomaly pattern.
