| Abstract: | Based on the space distribution characteristics of diurnal variation of geomagnetic, inverse latitudinal- difference weighting method with the multi-observatories is presented and analyzed. The feasibility of the method has been testified by three observatories synchronous observed data. The result shows that the diurnal geomagnetic correction accuracy can be effectively improved by the method discussed in this paper. |
