Abstract :
We present an experimental high-precision ultrasonic positioning system based on a sensor network. The network can track an object moving along a straight line with an accuracy of 1 cm. The bulk of the position calculation is distributed, with sensor nodes exchanging only the times-of-flight of the ultrasonic pulses, and state information.
