Abstract : A position and velocity determining system, that uses two functioned receiver-transmitters. In performing a first function, each receiver-transmitter transmits an acoustic pulse at a unique frequency, in response to a first received acoustic pulse. In performing a second function, each receiver-transmitter transmits a continuous acoustic signal at a unique frequency, in response to a second received acoustic pulse. (Author)
