METHOD AND APPARATUS FOR POSITIONING

摘要

PURPOSE: A wireless location measuring method and device thereof are provided to supply a superior location measuring result. CONSTITUTION: A TDOA(Time Difference of Arrival) performing unit applies a TDOA method to signals received from transmitters through a signal receiving unit. A controller compares the error rate of the TDOA performing unit with a threshold error rate(S210). If the error rate of the TDOA performing unit is smaller than the threshold error rate, a location determining unit determines the location of the receiver using only a result of the TDOA performing unit(S220). If the error rate of the TDOA performing unit is larger than or the same as the threshold error rate, the location determining unit determines the location of the receiver by combining the result of the TDOA performing unit with a result of the RSSI performing unit(S230).
