Positioning signal receiver, positioning system and positioning method of the same
A positioning signal receiver that includes an electromagnetic wave receiver, a mechanical wave receiver and a processing circuit is provided. The electromagnetic wave receiver receives electromagnetic wave signals for indicating positions of positioning signal transmitters and for triggering the positioning signal transmitters to generate mechanical wave signals. The mechanical wave receiver receives the mechanical wave signals. The processing circuit is coupled to the electromagnetic wave receiver and the mechanical wave receiver and determines the positions of the positioning signal transmitters according to the first electromagnetic wave signals, determines signal transmission times of the mechanical wave signals and determines distances each between one of the positioning signal transmitters and the positioning signal receiver according to the signal transmission times. The processing circuit determines a position of the positioning signal receiver according to the distances and the positions of the positioning signal transmitters.
