Abstract

A method and a device of positioning based on wireless signal indexes are provided by the present disclosure. The method takes the wireless signals sent by the target to be located and received by all the receivers as inputs in sequence, and considers influence of the wireless signal indexes received by the current receiver for a current time and for a previous time as well as the wireless signal indexes received by all the receivers in the predetermined historical duration during positioning calculation, so as to calculate a position offset value of the target to be located and finally obtain the current coordinate position of the target to be located.
