A Cost-effective Local Positioning System Architecture based on TDoA

摘要

Joining the capabilities of two different worlds, location/positioning systems and RFID systems, is the aim of the Real Time Location System (RTLS) described in the present paper. Here we propose a cost-effective architecture for such a system based on Time Difference of Arrival (TDoA). Delay measurement of very small time intervals is also approached. Trial experiences in controlled medium results were made and shown the effectiveness of such methods.
