不同类三维空间定位网联合处理的坐标转换模型

The Transformation Models for Combining Different Types of 3-D Positioning Networks

  • 摘要: 本文分析了不同类的三维空间定位网(简称为空间网或三维网)联合处理时,坐标转换摸型定义上的差别,从统计学角度定义了空间网系统性尺度误差,区分和讨论了不同类空间网的不同尺度特性,在提出理论模型的基础上,分析了各类空间网联合处理时的实用转换模型的特性和偏差。最后,提出了多类空间网联合处理时的最佳转换模型。

     

    Abstract: In this paper,We have analysed the differences in the definition of coordinate transformation models between different types of 3-D positioning networks(abbreviated as space networks) for the combination of them and strictly defined the systematic scale biases of space networks from the point of probability and statistics.The properties of the scale biases,inherent in the space networks of different type,are discussed and identified.Basing upon the theoretical transformation model put forward in this paper,we have also analysed the properties of various practical transformation models as well as their biases in the combination of different types of space networks.Finally,a comprehensive model for combining different space networks(VLBI,SLR,GPS and terrestrial network) has been proposed.
