We proposed a three-dimensional indoor ultrasonic positioning system that base on CDMA technology. It can achieve high localization and real-time centimeter-level positioning accuracy. The system is fast positioning and high precision positioning The system can achieve the positioning of multiple mobile target nodes, so that multi-objective positioning or navigation applications also become possible, especially for the multi-objective work in the room, such as the precise location of the underground personnel, medical care, 残骛 capture the remote object, indoor UAV, and paining the path of the robot and so on. 楼諍锩瀨濟溆塹籟。 Key words: CDMA ；Three-dimensional dynamic；RF synchronization； Ultrasonic 酽锕极額閉镇桧猪訣锥。
