At each of a plurality of second instances of time, a phase of a second signal at a second frequency from the transmitter is determined. A position or velocity of the transmitter is determined based at least in part on the phases of the first and second signals at the first and second instances of time.1/6 .10212 1020 1 102104 rAM0
