An orientation method based on directional antennas is proposed according to the difference of signal coverage area. The transmitter transmits different signals to different directions, and the coverage areas of different signals would be overlapped to some extent, therefore the receiving terminal can receive one or more different signals. By analyzing the signals received, the receiving terminal’s direction relative to the transmitting terminal can be determined according to the transmitter signal overlay. The proposed orientation method can determine the direction without satellite positioning signals, mobile data network services or paving locating nodes in advance.
