为了获得较好的捕获性能，解决 Galileo E1 OS（开放服务）信号捕获过程中遇到的2个问题：信号功率利用不够充分，以及捕获结果的多峰错锁与相位模糊问题，设计了一种利用BPSK-like 技术的双通道信号捕获方法。将此方法应用于实测信号，捕获结果主峰明显、几乎无旁瓣，捕获性能理想。

To obtain a better performance of acquisition, and solve two problems of acquisition of Galileo E1 OS(Open service) signals: not exploiting the signal power adequately and multiple peaks autocorrelation function allowing lock on secondary peaks with a non-zero probability, we designed a new method using BPSK-like technology and joint data/pilot acquisition strategies for acquisition of Galileo E1 OS signals after the analysis of the foregoing problems. Then we analyzed the real signals using the method. The results displayed an ideal acquisition figure which had a standard waveform and low secondary peaks.
