A method, device, system and use for determining a distance, location and/or orientation including the at least relative determination of a position of at least one object using at least two active anchors. A first signal is emitted by a first of the two anchors and is received at the object and by a second of said two anchors. A phase measurement is performed at said second anchor and wherein a distance determination with respect to said first anchor is performed and/or the distance from said first anchor to said second anchor is known. A second, particularly electromagnetic, signal is emitted from said second anchor, and information on phase measurement and distance between said first and second anchors is made available to a computation unit and at least one phase measurement respectively of said first and second signal is performed at said object and made available to said computation unit. |

1. A method for distance measurement, the distance measurement being performed on the basis of transmitting, particularly electromagnetic, signals between at least two objects and measurements of phase angles at said at least two objects, wherein from each of said at least two objects several signals are being emitted and analyzed with reference to their phase angle, said signals being at least partially emitted at different frequencies, said method being performed in at least two stages, wherein in a first of the at least two stages at least one measurement with at least two emissions with a frequency difference between frequencies of successive emissions with frequencies that have not been used in this stage, at least not by the emitting object, is performed, said frequency differences being selected from a start-measurement frequency difference range and selection of a measurement-frequency difference range on the basis of such at least one measurement in said first stage, wherein in a second of said at least two stages at least one measurement with at least two emissions with a frequency difference between frequencies of successive emissions with frequencies that have not been used in this stage, at least not by the emitting object, is performed, wherein said frequency differences are selected from the selected measurement-frequency difference range. |
