对于GPS接收机基带信号的捕获即,当接收机产生的码相位和载波频率必须与接收到的码相位和载波频率相匹配,使得相关值高于信号检测阈值,完成伪码捕获和载波频率捕获,进而对信号进行跟踪.

Answer 1

For capture the GPS receiver baseband signal,when the code phase and carrier frequency receiver must with the received code phase and carrier frequency,makes the correlation value is higher than signal detection threshold,the complete capture capture of pseudo code and carrier frequency,and then the signal tracking
