Abstract
Aimed at the high dynamic problem of GPS receivers in precise attack weapons, a GPS receiver with high order phase-lock loop is studied. The high dynamic tracking performance of a third-order loop is analyzed and the problem in tracking high dynamic GPS signals is investigated. Then, some methods are put forward to solve this problem, such as the bandwidth and the loop gain changed continuously. Simulation results show that these methods are effective.
