A method for local positioning of movable objects with use of ultrasound and radio channels based on US range measuring method that determines coordinates of one object, that for one sets the range of positioning and arrangement of navigation points there, those emit US signals. One positions several movable objects, this is carried out as follows: by means of a basic station by radio-channel time counters of US marks are synchronized, with the instant of emission of US signal with navigation points, the US marks receive the signal and counters of those fix the delay time for the signal that is transferred by radio-channel to basic station by inquiry with the number of the US mark, the basic station in its turn sends information obtained to PC for following processing and determination of coordinates of each mark, at that positioning of movable objects is carried out by means of US marks fixed on those. |
