摘要
介绍了两种差分 G PS定位模型 ,它们是码差分定位和 RTK ( real tim e kinem atic)定位 ,讨论了多径效应对码差分定位和 RTK定位精度的影响。利用 Javad G80采集数据 ,最后通过分析这些数据的统计特性 ,得到的计算结果表明 :影响差分 GPS定位系统精度的主要原因是多径效应和接收机噪声。
In this paper, two models of differential GPS, which are code differential GPS and real time kinematic (RTK), are introduced, and the effects of multipath on code differential GPS and RTK are discussed. The data is collected by Javad G80 GPS receiver. By investigating the stochastic characteristics of the data, the calculation results shows that the principal cause, which influence on the position accuracy of differential GPS, are multipath effect and receiver noise.
