FIELD: measurement technology; radio engineering. SUBSTANCE: movable objects radiate signal, which is subsequently re-radiated by reference stations. In this case a set of signals is formed, which permits to determine location of any movable object in any geographic point within the boundaries of active zone of the system. EFFECT: improved precision. 4 dwg
