Abstract
A self-positioning portable electronic device comprises a signal receiving unit for receiving a signal from one or more remote transmitters, and a local positioning unit for determining a local position of the device. The device operates to obtain a plurality of data samples from the signal at different time points during a measurement period with movement of the portable electronic device along an arbitrary trajectory, associate each data sample with a local position obtained from the local positioning unit so as to form a synthetic antenna array, obtain an array response of the synthetic antenna array, and identify the geographic location of the portable electronic device, by processing the synthetic antenna array as a function of the array response and using knowledge about the geographic location of the transmitter(s).
