Abstract

Large-scale low earth orbit (LEO) constellations can enhance traditional global navigation satellite systems (GNSS) in many ways, but the rapid increase in the number of LEO satellites also poses challenges to the anti-interference performance of navigation signals. To improve the performance of the B1C signal in the future BeiDou global navigation satellite system, this paper proposes a modulation method: it enhances the existing quadrature-multiplexed binary offset carrier (QMBOC) by using periodic binary hyperbolic frequency modulation (HFM) signals as subcarriers. The enhanced QMBOC signal (QMBOC-HFM) demonstrates superior anti-interference and positioning accuracy compared to the original QMBOC signal. The proposed QMBOC-HFM provides a potential signal design for future LEO navigation-augmented global satellite navigation systems.

QMBOC- hfm:用于大规模LEO导航增强系统的增强型QMBOC
大尺度近地轨道星座可以从多个方面增强传统的全球导航卫星系统,但近地轨道卫星数量的快速增加也对导航信号的抗干扰性能提出了挑战。为了提高未来北斗卫星全球导航系统B1C信号的性能,本文提出了一种调制方法:利用周期二进制双曲调频(HFM)信号作为子载波,对现有正交复用二进制偏置载波(QMBOC)进行增强。增强的QMBOC信号(QMBOC- hfm)与原QMBOC信号相比,具有更好的抗干扰性和定位精度。提出的QMBOC-HFM为未来的LEO导航增强全球卫星导航系统提供了一种潜在的信号设计。
