GPS/GLONASS组合精密单点定位模型及结果分析

Modeling and Result Analysis of Combined GPS/GLONASS Precise Point Positioning

    摘要
  • 摘要: 在GPS和GLONASS观测方程中考虑硬件延迟偏差的基础上,推导了GPS/GLONASS双系统组合精密单点定位的数学模型,并分析了硬件延迟偏差对估计的未知参数的影响。利用IGS跟踪站的观测数据和动态实验数据,对组合GPS/GLONASS精密单点定位模型进行了试算,并与GPS单系统精密单点定位的结果进行了比较。

     

    Abstract: Based on the fact that GPS and GLONASS measurements contain hardware delay biases,the mathematic model of the combined GPS and GLONASS precise point positioning(PPP) is derived and the influence of the hardware delay on estimated unknown parameters is further analyzed.The existence of the hardware delay biases is validated by results obtained from several IGS stations.The combined GPS/GLONASS PPP model is tested using IGS static data and kinematic data collected from an experiment.The obtained numerical results are analyzed with a comparison to that of GPS-only PPP.
