GPS接收机
摘要：
本发明公开了一种GPS接收机，当在相关处理之前进行相干处理时，不必使用从外部取得的导航电文，就可校正C/A码的极性反转，并可对C/A码进行积累相加。在对从GPS卫星接收的GPS信号进行积累处理后，使用在内部生成的C/A码的复制品进行相关处理的GPS接收机中，在积累处理中，在接收的GPS信号上累计多个累计用信号，并就该累计的结果进行积累相加，各个累计用信号是预测基于导航电文的GPS信号的调制而在内部生成的信号。
摘要（英）：

A GPS receiver which performs correlation processing by using replicas of C/A codes generated in the GPS receiver after a GPS signal received from a GPS satellite is subjected to accumulating processing, wherein in the accumulating processing, a plurality of signals for integrating generated in the GPS receiver by predicting modulation of the GPS signal by a navigation message are integrated withthe received GPS signal, and results of the integration are accumulatively added.
