First Claim
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.

Abstract
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.

47. 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 angels 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 angel, 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.

48. A method for the correction of an influence to a distance measurement between at least two objects, providing a first and a second object, wherein said influence originates from relative movement between said at least two objects, wherein said distance measurement is performed on the basis of transmission of, particularly electromagnetic, signals between said at least two objects, and measurements of phase angels of the signals are carried out at said first and second object;
-
wherein from each of said at least two objects, particularly from all objects, at any given time only one signal is emitted; and wherein the distance change and/or the change of the phase shift due to the distance change between said objects is determined between the individual transmissions and is taken into consideration in the determination of the distance.

49. A method for the analysis of a, particularly electromagnetic, wave field, particularly in relation to at least one propagation direction, particularly location, and/or orientation, wherein from at least one emission-device arrangement of an emitter, m signal sequences which are de-correlated against each other with A signals respectively having a known phase relation to each other, are emitted via s different emission devices and/or different places and/or orientations of the emission-device arrangement, wherein s is greater than or equal to two, wherein A is greater than or equal to two and wherein particularly m is greater than or equal to two, and wherein at at least one, particularly mobile, receiver, particularly with only one reception device, reception is made, wherein an emission characteristic of the emission-device arrangement is being used, particularly in the form of at least one matrix, in order to determine the propagation direction of the signals to the receiver, particularly location and/or orientation of the receiver as seen relatively from the emitter and/or of the emitter.
