GPS网型结构与定位精度关系的实验研究

Study on the Relationship between GPS Position Precision and Its Net Type Structure

实际测量表明,GPS网型结构对GPS定位精度是有影响的。长期以来,这种影响的成因与影响规律人们一直没能彻底弄清。鉴于此种情况,在专用试验网上,通过不同的组网形式,对GPS的定位精度进行了对比试验,初步总结出了网型结构与GPS定位精度的关系。

It is confirmed by surveying practice that GPS position precision depends on its net type structure. The relationship between GPS position precision and its net type structure is a difficult question for a long time. This paper introduces the basic circumstances of the contrast test of GPS position precision through different net type combination in a special - purpose test place. It gets initial results of relationship between GPS position precision and its net type structure.
