| Abstract: | In this paper,absolute observation data of geomagnetic stations in Henan Province and its surrounding area are collected,spatial correlation analysis and its precision check are made by least squares method.The result indicate that precison of observation data of class 3 geomagnetic stations of Henan is higher,the precision and stability of the total magnetic field intensity are better.The various index of precision between Zhengzhou Station and Xinyang Station are all first,and the quality of observation data is best. |
