Abstract:
A method and device determines an evolving position of a device using electromagnetic interference, which is jamming electromagnetic navigation signals. An antenna arrangement receives both the electromagnetic navigation signals and the electromagnetic interference. A discerned position is determined for each of one or more jamming antennas emitting the electromagnetic interference. A detection circuit determines each discerned position from the electromagnetic interference received at the device and at least one measurement of the evolving position using the electromagnetic navigation signals. The evolving position of the device is determined while the electromagnetic interference prevents subsequently measuring the evolving position using the electromagnetic navigation signals. An evaluation circuit determines the evolving position from the electromagnetic interference received at the device and from each discerned position of the one or more jamming antennas.
