| Abstract: | The conception of magnetic declination and the general observation principle through GPS are presented. The operating procedure and data processing method are introduced to measure magnetic declination through solar observation. The influence of the solar apparent motion is reduced. The mathematical models are created to calculate sun azimuth on the basis of the observation point＇ s longitude and latitude and measure time. The magnetic declination measuring method through solar observation is verified by a set of practice measurements and the accuracy analysis. |

| Keywords: | magnetic declination solar azimuth astronomic position measuring method data processing model |
