Proposal and Analysis of a New Direct Acquisition Technique of P-Code in GPS
Yongxin Feng · Transactions of Shenyang Ligong University · 2006
P-code is usually acquired depending on C/A code.But,P-code direct acquisition should be implemented in GPS receiver in order to achieve the higher spectrum-spread gain,the better anti-deception and anti-spoofing,without needing to rely on the other short-code to capture.A new P-code direct acquisition algorithm is proposed by studying direct signal acquisition algorithms.The simulation result shows that the algorithm is effective.
