摘要
为了提高GPS软件接收机信号捕获的速度,提出了一种GPS卫星C/A码信号捕获的新方法(这种方法具有Gold码的性质)。并证明了多颗卫星信号的相关性可以在同一次相关性计算过程中同时处理完成,在一次捕获卫星信号过程中可同时捕获多颗卫星信号。
For accelerating the speed of acquisition of the GPS satellite signal, a new way which is based on the property of the Gold code for code and frequency acquisition of GPS C/A signals is proposed. It is proved that the correlation between multi-satellite signals can be computed at the same process of the correlation computing, and in the proposed way multi-satellites C/A signals can be acquired at the same time.
