摘　　要：本文分析了安卓智能手机基于PPP技术的BDS/GPS组合定位的精度和可靠性,详细评估了在动态测试和静态测试下智能手机的PPP定位性能.结果表明,单GPS系统动态与静态测试定位精度E、N方向分别为2.14 m、2.13 m、0.72 m、1.80 m,组合系统在动态与静态测试定位精度E、N方向分别为1.57 m、1.20 m、0.51 m、1.22 m,组合系统定位精度高于单GPS系统.This paper analyzes the accuracy and reliability of the BDS/GPS combined positioning of Android smartphones based on PPP technology and evaluates the PPP positioning performance of smartphones through dynamic and static tests in detail.The results show that the positioning accuracy E and N directions of the single GPS system in dynamic and static tests are 2.14 m,2.13 m,0.72 m,and 1.80 m respectively.And the positioning accuracy of the combined system in the dynamic and static tests in the E and N directions is 1.57 m,1.20 m,0.51 m,and 1.22 m respectively.It can also be seen that the positioning accuracy of the GPS and BDS combined system is higher than that of the single GPS system.
