摘要
提出利用基于小波变换的Kriging估计将GPS高程转换成正常高,给出了小波方法结合Kriging方法应用于GPS高程转换的途径,并对一个GPS网的高程进行计算分析,计算结果证实运用该方法估算正常高的精度可以达到厘米级,表明小波方法的Kriging估计能获得较为理想的正常高。
A conversion method of GPS geodetic height to normal height by using Kriging algorithm based on wavelet transform is proposed in this paper, It was not only studied how the wavelet method combining with Kriging algorithm and used in GPS height conversion, but also a GPS height example was analyzed. It is pointed that accuracy of conversion is about the order of 3cm. The results indicate that GPS normal height is gained by the method and it can be referenced and utilized.
