摘要
设计了一种基于卫星共视法的北斗三号全球卫星导航系统(BDS-3)时差测量实验教学装置,给出了BDS-3卫星共视法时差测量算法模型。基于Visual Studio开发平台,利用C#编程语言设计开发了实验软件系统,并从实验硬件装备和实验软件设计两个角度搭建BDS-3时差测量实验教学装置。初步试验结果表明,基于卫星共视法的BDS-3时差测量实验教学装置运行稳定、状态良好,且用于B1伪距信号时差测量实验获得接收机钟差稳定度为纳秒级且时差测量精度可达23.0 ns,该算法模型及实验教学装置设计有利于学生理解和掌握时差测量的相关知识与技能。
An experimental teaching device of BDS-3 time offset determination based on satellite common view algorithm is designed,and the BDS-3 time offset determination algorithm model via satellite common view is given.Based on Visual Studio 2010 development platform,the BDS-3 time offset determination experimental software system based on satellite common view algorithm is designed and developed by using C#programming language,and the BDS-3 time offset determination experimental teaching device is built form two aspects i.e.,experimental hardware and experimental software.The preliminary application testing results show that the BDS-3 time offset determination experimental teaching device based on satellite common view algorithm has good operation stability states,and the stability of receiver clock error is ns-level.The accuracy of time offset determination can reach 23.0 ns when it is used in the experimental of B1 pseudo-range signal.The algorithm model and experimental teaching device design are feasible and effective.
