| 英文摘要 | 全球导航卫星系统(gnSS)信号软件模拟器能够根据需要,方便灵活地模拟出接收机收到的导航信号,可为gnSS导航算法的测试、评估以及接收机的研发测试提供一种高效的方法。对基于软件架构的gnSS数字中频信号模拟技术进行研究。首先分析了导航信号中出现的各种误差信号,然后给出整个系统的设计架构,最后分别运用gnSS软件接收机和硬件接收机对模拟信号进行验证。结果表明gnSS数字中频信号软件模拟的信号可以用标准的gnSS接收机进行正常接收和定位,可以用于gnSS接收机的研发测试。; Software-based global navigation satellite system(GNSS) signal simulator can simulate navigation signals received by receivers conveniently and flexibly according to needs,which provides an effective way for both GNSS navigation algorithm test & evaluation and receiver development & test.This paper studies the simulation of software-based GNSS digital IF signal.First the various errors that appear in navigation signal are analyzed,and then the architecture of the entire simulation system is proposed.Finally the accuracy of the simulated signal is verified via GNSS software receiver and hardware receiver respectively.The results show that the signal generated by GNSS digital IF signal simulator can be received and positioned by standard GNSS receiver,and can be used in GNSS receiver development and test. |
