Abstract:

In this research note, a method for determining azimuth and latitude, independent of time and zenith distance is given. The solution is based on the recording of the horizontal circle readings when three or more different stars reach the same but unknown zenith distance. A minimum of three stars is required for the solution, and the time required for making the computation is less than 4 minutes. When more than three stars are observed at the same altitude, the set of independent equations is solved by the method of least squares. A detailed analysis of the errors upon azimuth and latitude is presented. Author
