The number of satellites has been increased and has become excessive for positioning by insatllation of satellites such as GPS, GLONASS, QZSS and Galileo. It is assumed that the positioning accuracy will decline when the receiver receives the satellite radio wave containing the large amount of error due to the multipath and delay of propagation. In order to predict the range error of each satellite signal on the observation point, the detection method of multipath has been investigated theoretically and empirically using the relationship of location of observation point, surrounding obstacles and each satellite. As a result, the method to select the satellite for positioning calculation has been developed by excluding the satellite wave containing multipath and by considering the geometrical combination of satellites.

卫星的数目已经增加，而且由于安装了诸如全球定位系统、格洛纳斯系统、QZSS和伽利略等卫星而无法进行定位。假设接收机接收到的卫星无线电波由于传播的多径和延迟，误差较大，定位精度会下降。为了预测各卫星信号在观测点上的距离误差，利用观测点位置、周围障碍物和各卫星位置的关系，对多径探测方法进行了理论和实证研究。在此基础上，提出了排除含多径卫星波并考虑卫星几何组合的定位计算卫星选择方法。
