A combined method of Doppler positioning and carrier-based hyperbolic positioning with a multi-channel GPS-pseudolite is proposed for indoor localization. This method uses carrier-phase output from a GPS/pseudolite receiver. The carrier-phase observa

A method for dramatically improving positioning accuracy of an indoor messaging system (IMES), whose accuracy is normally 10-20 m, was developed. This method uses Doppler shifts (produced by moving...

IMES is an indoor messaging and positioning system. In the present work, three methods for improving the IMES transmitter are proposed based on the result of a radio acquisition analysis: transmission diversity, a variable beamwidth antenna, and a le

An indoor messaging system named the Indoor Messaging System (IMES) is expected to be an indoor positioning infrastructure. However, conventional IMES signal transmitters have three major issues: oscillator's cost, low usability, and wired-configurat

Indoor positioning still remains as an open problem, for the reason that it is difficult to achieve a satisfactory level of accuracy within indoor environment, using current radio based localization technology. Thus we try to investigate the utilizat
