Abstract :
We developed a positioning system using impulse radio UWB. The system consists of tags equipped only with transmitters and nodes provided with both transmitters and receivers. The system calculates the position of the tags using the TDOA method, whereby some nodes receive the UWB pulses sent from a tag. The tag is operated with a coin battery, and sends UWB pulses intermittently. The node sends the receiving time data to a PC via an Ethernet network for position calculation. We developed a time clock correction method, which is also required for the TDOA method. We will further evaluate positioning accuracy etc. in the future
