| 摘 要： | 主要介绍了北斗与G PS组合单点定位时的原理和模型，根据自编程序，利用同济大学TJA站的数据进行计算及分析比较GPS伪距、北斗伪距、北斗/GPS组合伪距单点定位的精度。结果表明：北斗伪距单点定位的精度平面方向上达到3m以内，高程方向优于8 m ，满足普通导航定位的需求。北斗/G PS组合伪距单点定位精度明显优于单系统。在单系统观测条件差时，组合系统可以减少对单一系统的依赖性，而且还可以增强卫星定位的稳定性和可靠性。

| Abstract: | With principles and mathematical models of the combined BeiDou/GPS pseud-orange point positioning introduced ,self-programming is used based-on Tongji University TJA station data for analyzing the precision of Combined BeiDou /GPS pseudorange point positioning ,then compared with GPS pseudorange and BeiDou pseudorange .As the plane precision get 3 m and vertical accuracy reach for 8m ,the BeiDou pseudorange positioning has been proven effective and can be applied for common navigation .T he precision of combined BeiDou /GPS pseudorange point positioning is more accurate than single system .Further-more ,the combined system can reduce the dependence on one system in bad observation con-dition ,and increase the stability and reliability of satellite positioning . |
