Abstract
An acoustic tracking system for determining a position of an object is provided that includes one or more receivers that detect an object based on an acoustic signal transmitted by one or more transmitters. The system also includes a processing component that determines a relative position of the detected object with respect to the one or more receivers and the one or more transmitters and selects at least three pairs of receivers and transmitters. Each selected pair includes a receiver from the one or more receivers and a transmitter from the one or more transmitters. The processing component also determines a position of the detected object using the selected at least three pairs of receivers and transmitters.
