摘　　要：该文通过对北斗多通道共视比对频率校准技术的研究,研制多通道北斗共视接收机,完成系统设计及硬件系统组建。为降低由于不同卫星俯仰角和方位角影响引入的计算误差,采用Kalman滤波和滑动平均方法进行数据分析;进行零基线和远距离比对试验,对共视比对系统的准确性和稳定性进行试验分析、总结,促进北斗系统在计量检定、校准工作中的推广使用,具有一定的参考价值。Based on the research of the frequency calibration technology of Beidou multi-channel common view comparison,this paper develops the multi-channel Beidou common view receiver,and completes the system design and hardware system construction.In order to reduce the calculation error caused by different satellite elevation and azimuth angles,Kalman filtering and moving average method were used for data analysis.Zero baseline and long-distance comparison tests are carried out to analyze and summarize the accuracy and stability of the common view comparison system,so as to promote the popularization and use of the Beidou system in metrological verification and calibration,which has certain reference value.
