A positioning system includes a signal transmitter and a signal receiver. The signal transmitter is to be attached to a movable object and includes a transmitting module configured to transmit an electromagnetic wave. The signal receiver includes at least three receiving ports arranged on an imaginary plane defined by a first axis and a second axis perpendicular to the first axis, spaced apart from one another in a direction along each of the first and second axes, and configured to receive the electromagnetic wave respectively as received signals. The signal receiver further includes a calculating module for calculating a position of the signal transmitter relative to the signal receiver on the imaginary plane based on the received signals. |
