Abstract: Location system and location method are provided to identify and measure the positions of multiple objects located on a plane, such as a game board. Each of the objects includes means for transmitting an identification signal. The location system includes at least two sensors and a processor. In a preferred embodiment, the system includes at least two sensors positioned at the peripheral of a plane such as the adjacent corners of a square or rectangular game board for receiving a first and a second identification signals sent by a first object and a second object respectively positioned on the game board. The processor is coupled to the two sensors for identifying and determining the positions of the objects according to the signal strengths and identities of the first and second signals received.
