The study of the impact of high dynamic environment on the GPS carrier tracking

Because of the loop bandwidth limited, Traditional GPS carrier tracking loop can not meet the conditions of the high dynamic tracking. In order to improve the adaptive capacity of the traditional high dynamic GPS carrier loop, the impact of high dynamic environment on the carrier tracking requires to be analysed in-depth. This paper analyzes the dynamics of the GPS signal, and then discusses the various parameters of the PLL dynamic performance, and the limitations of the traditional carrier tracking loop; Finally, we use the traditional carrier loop tracking carrier of high dynamic signal, and shows the correctness of the previous theoretical analysis,. This will contribute to design a new high dynamic carrier loop.
