无源北斗一号接收机测距测速精度分析

Precision Analysis of Range and Velocity Measurement of Beidou-1 Receiver

针对气压高度辅助的北斗一号接收机,给出了定位测速模型,并提出了带有模糊逻辑控制器的跟踪测量环路、伪距和积分载波相位测量方法。最后定义了气压高度辅助的北斗导航下的几何误差因子,并分析了其对定位精度的影响。研究结果为国内北斗一号接收机的研制提供了理论依据和参考价值。

Firstly, the positioning and velocity measurement model was given for barometric altimeter aided Beidou-1 receiver, then the tracking and measurement loop with fuzzy logic control was proposed. At last, the DOP of barometric altimeter aided Beidou navigation was given, and the effect of DOP on positioning accuracy was analyzed. The research results provide references for development of Beidou-1 receiver.
