【摘要】 星基增强系统(Satellite-Based Augmentation System,SBAS)用于增强GNSS的观测值,以提高定位精度和进近导航的可用性。随着SBAS的发展,现已可以利用同步轨道卫星进行双频多星座(Dual Frequency Multiple Constellation,DFMC)星基增强服务。日本QZSS(Quasi-Zenith Satellite System)通过L5S信号进行QZSS DFMC服务验证。本文聚焦于SBAS/QZSS DFMC信号体制比较,总结了SBAS DFMC L5信号格式以及QZSSDFMCL5S信号格式,比较了QZSSL5S和其他信号的不同。用实际数据对SBAS/QZSS DFMC信号进行了接收测试,给出了BDSBAS B1C/B2a、GAGAN L1/L5、QZSS L1S/L5S等信号的测试结果。更多还原

【Abstract】 Satellite based augmentation system(SBAS) is used to enhance GNSS observations to improve positioning accuracy and approach navigation availability. With the development of SBAS, GEO satellites can be used for dual frequency multiple constellation(DFMC) satellite based augmentation services. Japan’s QZSS(Quasi-Zenith satellite system) has also transmitted L5 S test signal for DFMC L5 SBAS. This paper focuses on the comparison of SBAS/QZSS DFMC signal system, summarizes the SBAS DFMC L5 signal format and QZSS DFMC L5 S signal format, and compares the differences between QZSS L5 S and other signals. The receiving test of SBAS/QZSS DFMC signal is carried out with antenna data, and the test results are listed, including BDSBAS B1 C/B2 a, GAGAN L1/L5, QZSS L1 S/L5 S, etc..更多还原
