摘要
Abstract
GNSS receivers rely on outer satellite radio-frequency signals, so they are vulnerable to intentional or unintentional signal interference. Research anti-jamming ability and technology of satellite receiver, among others the ammunition-loading satellite receiver. Analyze anti-jamming ability of satellite receiver from signal to noise ratio and tracking threshold. Through comparing analysis of receiver signal to noise ratio when there is anti-jamming signal or there is no anti-jamming signal, and receiver anti-jamming ability analysis under different tracking threshold. The results show that the method can effectively improve receiver anti-jamming ability without changing receiver hardware structure and increasing cost.关键词
