Abstract
There is provided a system and method for positioning a receiver, the system comprising an antenna array coupled to a common generating and switching unit. The generating and switching unit is configured to generate a periodic signal and to switch the signal between at least two antennas, constituting a positioning signal; such that an RF receiver receiving the positioning signal and having a phase difference estimator is capable to measure phase differences between portions of the positioning signal transmitted by the spaced-apart antennas, the phase differences indicating the orientation of the received relative to the positioning system.
