| Abstract: | this paper expounds two direct solutions of position fixing by altitudes of celestial body:direct analytic method and iteration method.By some examples the paper shows the above two ways avoid the errors which are present in altitude interception method, and are useful for fixing position of high altitude of the sun.The calculation accuracy of position is within 0.1 n mile. |
