1. A system for tracking an object in space for position, comprising:

  • a transponder device connectable to the object, the transponder device having a transponder aerial and a transponder circuit connected to the transponder aerial for receiving an RF signal through the transponder aerial, the transponder device for adding a known delay to the RF signal for thereby producing an RF response for transmitting through the transponder aerial;

    first, second and third aerials;

    a transmitter connected to the first aerial for transmitting the RF signal through the first aerial;

    a receiver connected to the first, second and third aerials for receiving the RF response of the transponder device therethrough; and

    a position calculator associated to the transmitter and the receiver for calculating a position of the object as a function of the known delay and the time period between the emission of the RF signal and the reception of the RF response from the first, second and third aerials.
