Based on B2a signal dual channel tracking algorithm in high dynamic environment
In the B2a signal of Beidou No.3,aiming at the problems such as slow convergence rate and poor stability of the track-ing loop of navigation receiver due to the large signal Doppler change under high dynamic environment,a dual-channel joint tracking carrier tracking loop based on the traditional tracking loop algorithm of Beidou B2a signal is designed and simulated.The experimental results show that the dual-channel joint tracking algorithm has significantly improved the signal utilization and fast loop convergence,and can achieve stable tracking in the case of poor signals,and the stability and accuracy are significantly improved.
