摘要: In this work, a time-of-arrival/time-difference-of-arrival (TOA/TDOA) hybrid relative positioning system based on UWB-IR technology is developed. The reduces both the complexity of configuration and number wireless transmissions in sequence. performance over various distances between access points verified by computer simulations experiments under assumption that distance less than point target node. For experiments, proposed implemented with in-house developed UWB transceivers. confirm TOA/TDOA can detect positions nodes (under condition two 4 m apart) measured-angle accuracy 8.6 degrees.
