摘要

为了保障中国第二代卫星导航系统(Compass)平稳顺利地运行

针对Compass的B2频点信号AltBOC(15

10)建立了完善的信号质量评估方案.通过对采集的Compass的B2频点信号进行离线处理

在信号功率谱、星座图、相关损耗、眼图及S曲线偏差这些质量评估参数上对AltBOC(15

10)信号进行了理论与试验分析

并评估出了基本性能指标;然后在不同环境中对码跟踪精度、抗干扰、抗多径性能上与BPSK(10)进行对比分析

评估出了AltBOC(15

10)的实际性能.结果表明新体制信号AltBOC(15

10)不论在开阔环境还是在多遮挡环境中的码跟踪精度

抗干扰性能以及抗多径性能

都明显优于BPSK(10).

Abstract

In order to ensure the Chinese second generation satellite navigation system(Compass) to work smoothly

a perfect signal quality evaluation scheme for the Compass of B2 frequency point signal AltBOC(15

10) was established.Through the acquisition of the Compass of B2 frequency point and acquisition of Compass signals was processed in off-line and the evaluations were done in signal power spectrum

constellation

loss

eye diagram and S curve deviation on AltBOC(15

10) signal theory and test analysis to assess a basic performance indicators

then the comparative analysis between BPSK(10) and AltBOC(15

10) was presented in the performance of code tracking accuracy

anti-interference and anti-multipath

the results turned out that the new system signal AltBOC signal.It is superior to BPSK(10) in the performance of code tracking precision

anti-jamming and anti multipath obviously

whether in the open environment or in the shade environment.
