摘要：
Utilizing the Ultra-Wideband(UWB), the positioning system based on the Time of Fight (TOF) and Time Difference of Arrival (TDOA) is realized in this paper. The test results present that the positioning accuracy can reach the decimeter level. By analyzing and comparing the advantages and disadvantages of the two methods, a joint positioning system based on TOF and TDOA is proposed. Wireless clock synchronization of TDOA is analyzed and new method of clock synchronization is proposed. This joint positioning technique has advantages of TOF. Positioning speed was higher than TOF but lower than TDOA. It can be used to replace TOF overall and replace TDOA with low positioning speed required.
