摘要： An apparatus, computer program and a chipset for performing a method, the method, comprising: receiving, at a first position and in a first reference system, a first radio signal from a signal source; determining a direction of arrival, in the first reference system, of the received first radio signal; receiving, at a second position and in a second reference system, a second radio signal from a signal source; determining a direction of arrival, in the second reference system, of the received second radio signal; detecting a displacement between the first position and the second position; and determining a distance to the signal source, by using the direction of arrival in the first reference system of the first radio signal, the direction of arrival in the second reference system of the second radio signal and a displacement between the first position and the second position.
