ACOUSTIC BASED POSITIONING SYSTEM AND METHOD

摘要

As described herein a system measures position of a model vehicle. The system includes an acoustic transmitter located onboard the vehicle that broadcasts an acoustic signal that is received by a plurality of acoustic receivers at fixed positions. The durations of time required for the acoustic signal to be received by the various ones of the acoustic receivers are measured and used to determine corresponding distances between each of the acoustic receivers and the acoustic transmitter. These determined distances are then used to arrive at a position for the acoustic transmitter and the associated vehicle based upon the known positions of the plurality of acoustic receivers. In some implementations, the acoustic signal used is an ultrasonic signal.
