According to the problem of local position information for automatic guided vehicle(AGV),a TDOA-SINS integrated navigation system is researched.By analyzing the principle of hyperbolic navigation based on the time difference of arrival(TDOA),the hyperbolic navigation system,which stations are constituted of multi-ultrasonic sensors is used.Those are bases of studying the structure and the filter model of the TDOA-DR integrated navigation system.The emulation results show that the TDOA-DR can provide high-precision location information which errors are several centimeters and the demand of the region locating can be met.
