摘要
根据伪码跟踪精度理论,以及北斗二期和三期B1,B3频点的信号设计体制,理论分析了北斗B1/B3频点载波相位测量和伪码测距的精度,并用北斗双频接收机零基线实验对理论精度进行了实际数据验证。研究结果对用B1/B3频点的载波相位和码测量进行精确建模应用有一定的指导意义。
According to the theory of pseudo-code tracking accuracy and the designed signal structure of B1/B3 frequency of BeiDou phase Ⅱand Ⅲ, the accuracy of carrier phase measurements and pseudo-code measurements were analyzed theoretically. The theoretical evaluation was verified by the actual zero-baseline data which employed the two B1/B3 dual frequency receivers. The study was useful for precise modeling applications using B1/B3 carrier phase and code measurements.
