Radio frequency identification (RFID) is influenced by the environment, when the RFID is used as an indoor location way. The signal intensity of e-tag becomes weak and can’t be read, which will decrease the location precision, and even cause the location system fail. An integrated location system based on RFID and dead reckoning (DR) is proposed to apply on indoor location of dynamic object. The RFID can eliminate the accumulative error with time. The DR system can assist the RFID system, when the e-tag signal lost. Based on the experiment, the integrated location system can improve the effect and precision of indoor location.
