Beschreibung
Zusammenfassung:	A positioning system and method are provided. The positioning system includes a wireless signal source disposed at a known fixed location in an area and a handheld electronic device. The handheld electronic device includes a compass, a wireless transmission module and a processing module. The processing module retrieves information of fixed direction from the compass, determines a first azimuth angle among the handheld electronic device, the wireless signal source, and the fixed direction according to a maximum signal strength between the wireless transmission module relative to the wireless signal source, and determines a first distance between the handheld electronic device and the wireless signal source according to a first wireless transmission parameter between the wireless transmission module and the wireless signal source. The processing module further determines a first absolute location of the handheld electronic device according to the first azimuth angle and the first distance.
