a remote receiver that acquires positioning signals from a terrestrial transmitter network;
wherein:
the remote receiver generates, for each of the positioning signals, a cross-correlation function by cross-correlating one or more signal samples extracted from that positioning signal with a reference sequence corresponding to that positioning signal;
the remote receiver determines, for each of the positioning signals, a vector of cross-correlation samples from the cross-correlation function by selecting a first set of cross-correlation samples left of a peak of the cross-correlation function and a second set of cross-correlation samples right of the peak of the cross-correlation function;
the remote receiver identifies, for each of the positioning signals, a time of arrival estimate corresponding to an earliest arriving signal path of one or more signal paths corresponding to that positioning signal using a high resolution time of arrival measurement method that uses the vector of cross-correlation samples; and
the remote receiver estimates a first position of the remote receiver based on the time of arrival estimate.
