Abstract:
1. A method for the at least relative determination of a position of at least one, particularly a passive, object using at least two active anchors; wherein a first, particularly electromagnetic, signal is emitted by a first of the at least two anchors and is received at the object and by at least a second of said at least two anchors, wherein a phase measurement is performed at least at said at least one second anchor and wherein at least also at said at least one second anchor a distance determination with respect to said first anchor is performed and/or the distance from said first anchor to said at least one second anchor is known, wherein a second, particularly electromagnetic, signal is emitted from said at least one second anchor, wherein an information on the phase measurement and the distance between said first and said at least one second anchor is made available to a computation unit, especially located within said object, wherein at least one phase measurement respectively of said first and said at least one second signal is performed at said object and made available to said computation unit, and wherein at least one distance difference between the distance between said object and said first anchor and at least one distance between said object and said at least one second anchor and/or at least one distance difference between the distance between said object and said first anchor and at least one length of a route from said first anchor via said at least one second anchor to said object is determined.
