Disclosed is a wireless positioning system and method that can perform a high-precision position tracking. The wireless positioning system includes a target device that is an object of wireless positioning, beacon devices and a processing unit. The beacon devices transmits wireless signals and sense reception time points of the wireless signals transmitted from the other beacon devices and the target device and received at time points after the transmission of the wireless signal. The target device receives the wireless signal transmitted from at least one of the beacon devices, and then transmits the wireless signal to the beacon devices. The processing unit obtains the position of the target device by calculating distances between the beacon devices and the target device using information about the reception time points of the wireless signals sensed by the respective beacon devices.
