XU Rui, SUN Yong-rong, LIU Jian-ye, et al. Research on TDOA-DR integrated vehicle navigation system V[J]. 2008, (4): 37-39. DOI: 10.13873/j.1000-97872008.04.003.
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.
