    Abstract: Ultrasonic location systems are provided. These ultrasonic location systems include two or more wave transmitters, two or more wave receivers, and a mapping component that controls the operation of the transmitters and the receivers. The mapping component relies on collaborative operation of multiple transmitters and multiple phased-array receivers where each of the transmitters emits a short burst of sound wave in a pre-defined sequence and after every burst all phased-array receivers detect the wave reflected from surrounding objects. The mapping component uses the position of the transmitters, the position of the receivers, the time of transmission, the time of reception, and the phase shift of the waves to calculate a time of flight and a direction of arrival for the reflections. The mapping component uses triangulation to determine a distance between any physical objects acting as sources of reflection and one or more physical objects having a recorded position relative to the receivers.
