Abstract

Abstract:

Large interval L/C dual-band navigation can significantly improve positioning accuracy and robustness, and will become the development trend of high precision satellite navigation system in the future. To reduce the complexity of dual-frequency terminals, a universal modulation scheme is designed, which not only meets the spectrum compatibility constraints of L/C-band, but also has good navigation performance. A combination of Orthogonal Frequency Division Multiplexing-Continuous Phase Modulation (OFDM-CPM) is proposed for L/C dual-band navigation. OFDM-CPM signals with the modulation index h=0.5 and the correlation length L consistent with the number of OFDM-CPM symbols are selected as L/C dual-band candidate navigation signals. Dual-frequency points are set, and the basic navigation performance indicators including compatibility, code tracking accuracy and anti-multipath interference are evaluated. The results show that in L-band, OFDM-CPM(15) has excellent code tracking performance and anti-multipath ability, and is easier to coexist with other candidate signals. In C-band, OFDM-CPM(10) can well take into account the out-of-band constraint and navigation performance requirements of C-band signals, and has the best performance in code tracking accuracy and anti-multipath interference, providing a choice for the design of navigation signal system of BDS in the future.

Key words: L/C dual-band navigation, modulation mode, Orthogonal Frequency Division Multiplexing (OFDM), Continuous Phase Modulation (CPM), navigation performance
