摘要
The present invention relates to a wireless positioning system and more specifically, to a wireless positioning system for realizing a time difference of arrival (TDoA) wireless positioning algorithm using an ultra wideband (UWB) asynchronous reference node. According to the present invention, it is easy to extend a wireless positioning range because the positioning algorithm enabling accurate position measurement in a TDoA position measurement system using an asynchronous reference node capable of performing UWB communication does not require an external signal source or an additional algorithm for synchronization between reference nodes.;COPYRIGHT KIPO 2014; [Reference numerals] (S400) Start (i=0); (S420) Acquire TDoA, RSS information from each reference node; (S430) Set prior target node position as initial position; (S440) Set initial position by RSS based positioning; (S450) Undetermined LSS estimator; (S460) Update target node coordinate; (S480) Confirm target node position (i=i+1)
