几种常用气象元素获取法的比较

The Comparison of Several Common Methods to Obtain Meteorological Data

本文讨论了气象元素误差对GPS相对定位所产生的影响。在此基础上对目前广泛采用的三种气象元素获取方法分别进行了误差分析。讨论了各自的优缺点及其适用范围,得出了若干有益的结论。

The effect of the error of meteorological data on GPS relative positioning is discussed in this paper. Then, the errors of three methods to obtain meteorological data, which are widely used at present, are analysed respectively. The merits, the demerits and application of each method are discussed, and some useful conclusions are given.
