AbstractThe method permits the precise determination of the azimuth of a target and the astronomical latitude of the observer, by observation to two unknown stars sufficiently symmetric with respect to the north direction and observed at different times.Compared with analogous methods employing only one unknown star, this method presents the advantage of reducing the time necessary for the observations, and provides a sufficient number of solution equations with a consequent improved accuracy of the results. Furthermore the proposed method does not require the dead-reckoning position of the observer, is independent of the time observation and does not require a knowledge of the ephemerids. Generally, no astronomical knowledge is required, except for the ability to observe stars.
