Abstract
A method for facilitating a relative position determination is disclosed, comprising: a first radio frequency (RF) communication device measures a first angle of arrival, being an angle of arrival of a first RF signal received from a second RF communication device; the first RF communication device senses its orientation at a first time, resulting in a first orientation; the first RF communication device measures a second angle of arrival, being an angle of arrival of a second RF signal received from the second RF communication device; the first RF communication device senses its orientation at a second time, resulting in a second orientation; the relative position of the second RF communication device with respect to the first RF communication device is determined using a difference between the first angle of arrival and the second angle of arrival and a difference between the first orientation and the second orientation.
