The design uses the single chip 2.4 GHz transceiver nRF2401A and the MSP430F123 micro-controller to build the integrated ultrasonic circuit.LabVIEW7.1 is used for software development to build an ultrasonic positioning system.In location test,the system can achieve the positioning precision of centimeter grade.The current system can be applied in large scale storage location system or built into a bigger managing position system for second exploitation.
