GPS在高精度基准线精密测量中的应用

Application of GPS in High Precision Base-line Accurate Surveying

针对高精度火箭橇实验滑轨基准线基准点间距短、密度大、测量精度要求高的特点,分析了GPS短基线定位误差的影响,对高精度基准线GPS网的测量精度、坐标基准、网形、观测及数据处理方法进行了设计,并对测量成果进行了精度分析。结果表明,GPS相对定位技术是高精度基准线精密测量的一种有效方法。

In view of the characteristics of short distance between reference points,high consistency of the points and high accuracy requisition of the accurate base-line for rocket sled test track,the positioning errors of short GPS baseline were analysed.And then,the measurement precision,coordinate datum,net configuration,observation and data processing method were designed,and uracy anaysis of the measurement results was done.The results show that,GPS relative positioning technology is an accurate and effective method for high accuracy baseline.
