A device for determination of location of rail transport comprises the first, second and third phase detectors, which inputs are connected to outputs of the first, second and third flow sensing magnetic heads placed along a rail, correspondingly. The distance between extreme heads is equal to record head gap width. The fourth and fifth flow sensing magnetic heads are placed from extreme flow sensing magnetic heads at the distance equal to a pole width of the head for longitudinal recording. |
