摘要

A method for determining a direction lying in a plane using the angle * forming said address with an address of known orientation in this plane characterized in that a magnitude which is a measure of the angle * is taken of the relative position two oscillations whose ratio of two pulses is an integer (* y *) and manifested in said plane so that the two oscillations have a corresponding phase angle * can also present this procedure the following features taken separately or according to various possible combinations: a. Is taken of the two oscillations a dimension determined by sin ** (See formula) **: b. The measured is formed by the instantaneous value of the amplitude of oscillation of higher pulsation ** (See formula) ** at the time the other oscillation (*) crosses zero; c. It is taken of the two oscillations measuring a magnitude equal to ** (See formula) **; d. The measured is constituted by the phase shift between two oscillations of the same frequency one formed by the oscillation of higher pulsation ** (See formula) ** and the other is obtained by a multiplication of the frequency of oscillation lower pulsation ** (See formula) **; and. The two modulated carrier wave oscillations in a manifest in the plane through the direction of orientation and the direction to be determined. F. a sector in which the magnitude ** (see formula) ** * varies each time differs radians.
