TITLE OF THE INVENTION: NAVIGATION METHOD FOR PRECISELY STEERING A FLYING OBJECT ABSTRACT OF THE DISCLOSURE A flying object is precisely steered by determining the position of the flying object with the aid of a trigonometric calculation. For this purpose pulse signals emitted in synchronism from two ground stations are received by the flying object and the time difference be- tween the two arrivals is measured. The flying object is also equipped with a clock which is synchronized with the clocks of the two ground stations. Thus, the emitting times are available in the flying object. Based on the measured time difference between the receipt of the two pulses and on the given emission time the coordinates of the actual position of the flying object are calculated. The calculated position coordinates are compared with position coordinates of a rated course stored in the air- borne equipment whereby a course deviation signal is cal- culated. The course deviation signal is then applied to the steering mechanism of the flying object to bring the latter back onto the rated course.
