Abstract

This paper deals with a method of computing a set of astronomical observations to two or more stars without requiring a knowledge of the approximate geographical position of the observer in order to obtain a fix. Programmes for use with the Hewlett-Packard HP 41/CV calculator and in BASIC language are included. The author also describes an extended application of the method to processing observations made by “radio sextants” to provide twenty-four-hour continuous positioning offshore without recourse to radio, satellite, or inertial positioning systems.
