Abstract
A method and device for processing a signal are described, wherein an estimate of a multipath-induced contribution to a demodulated navigation signal is calculated and subtracted from said demodulated navigation signal to obtain an estimated line of sight contribution to said demodulated navigation signal, and a propagation time .tau..sub.0 is calculated from the thus calculated line of sight contribution to said demodulated navigation signal, such that a very accurate propagation time .tau..sub.0 of said navigation signal can be calculated.
