Research on Multi-peaks Non-fuzzy Tracking Algorithm of BOC Signal Based on Improved Bump-jumping Method
Pages 151 - 156
Abstract
The GPS-III navigation signal adopts the BOC modulation mode. The signal modulated by BOC will have multiple subpeaks when it is captured and tracked, so there is a large error caused by the subpeak wrong locked in the time delay difference measurement. In this paper, the bump-jumping algorithm is proposed, which can quickly identify the subpeak and ensure that the PLL is ready to lock the main peak. After locking the main peak, the algorithm is not easy to be disturbed and lead to loss of lock. Finally, the high-precision tracking of non-fuzzy BOC signal can be realized by using bump-jumping tracking algorithm.
