A device for determining the position and/or orientation of a creature ( 3 ) relative to an environment, comprising a locating member ( 4 ) connected to the creature ( 3 ), the locating member including a transducer ( 5 ) arranged to determine its position and/or orientation relative to the environment by receiving incident signals from signal sources ( 9 ) in the environment and record the relative incident directions of the signals received in relation to the transducer, and an element ( 8 ) by which the creature ( 3 ) and the transducer ( 5 ) are connected to each other, so that the relative positions and/or orientations of the creature ( 3 ) and the transducer ( 5 ) are arranged to be within a limited interval, for determining the position and/or orientation of the creature ( 3 ) by the information about the position and/or orientation of the transducer ( 5 ). |
