Abstract

A method and an arrangement for determining the delay of a signal between a first station and a second station of the arrangement, with the aim of determining the spatial distance between the stations. A first series of first signal pulses is generated in the first station at a first pulse repetition rate f1. A second and a third series of second and third signal pulses is generated in the second station, comprising a second f2 and third pulse repetition rate f3, where f2=f1+Δf and f3=f1−Δf. The second and third series of second and third signal pulses are transmitted to the first station, where the series are correlated with the first series of first signal pulses. The delay of the signal can be determined from the time elapsed between two successive pulses of the signal arising from the correlation.
