Short Studies on Indoor/Outdoor Seamless Positioning by Using Indoor MEssaging System (IMES) for Pedestrian Navigation

Abstract

In this study, an Indoor MEssaging System (IMES) was used to determine walking positions in an indoor situation at rates of 50 and 250bps, transmitting powers of -65 and -85dBm, set heights of 1.63 and 2.67m, and one, two, or four receiver channels. The results confirm that the best tracking of pedestrians in an indoor situation is achieved using IMES with a transmitting power of -65dBm, set height of 2.67m, rate of 250bps, and four receiver channels. The results of these experiments will be of use for new IMES/GNSS chip set designs.
