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.

A method includes receiving, using radio frequency (RF) collectors, RF signals from a target object. The RF signals of target object may be converted to In-phase and Quadrature (I/Q) data. Navigation data of each RF collector may be determined and I/Q data of each of RF collectors are paired. Processing functions may be applied on paired I/Q data. Using paired I/Q data, one or more of time difference of arrival (TDOA) measurement data and frequency difference of arrival (FDOA) measurement data between each pair of the RF collectors are determined. One or more of TDOA measurement data, FDOA measurement data and navigation data of each RF collector are converted to message data. A trajectory of target object may be estimated based on confidence measure of one or more of TDOA and FDOA measurement data. Using estimated trajectory of target object for displaying on a display device of a computing device.
