Abstract
The invention relates to a method for determining the position of a first sensor node relative to a second sensor node, wherein the first and the second sensor nodes are communicatively connected to each other and are a constituent part of a sensor network, comprising the method steps: reception of signal sections of transmitted signals from at least two transmitters by the first and the second sensor node, beginning at a time tfor a time period t; determining the angle of incidence of the transmitted signals to at least one of the sensor nodes; determining the distance between the sensor nodes from the propagation time differences of the transmitted signals from the at least two transmitters received at the first and second sensor nodes; determining the position of the first sensor node relative to the second sensor node from the distance between the sensor nodes and the angle of incidence of the transmitted signals, wherein the sensor nodes determine the time tand the time period tin relation to a reference frequency which is derived from the received transmitted signal from at least one of the transmitters.
