The last decade has witnessed an increasing trend in the use of positioning and navigation (POS/NAV) technologies in wide range of applications. The recent advances in information and communication technology necessitate the development of reliable POS/NAV systems. Wireless positioning technologies including Global Navigation Satellite Systems (GNSS) like GPS in open sky and wireless Local Area Networks (WLAN) indoors are presently widely used for POS/NAV applications. However, they still suffer from several shortcomings such as signal blockage, interference and multipath in some challenging environments. Integration of GNSS/WLANs with other sensors (like accelerometers, gyroscopes and magnetometers) and systems (like vision, radar and LiDAR) can bridge the accuracy gaps in such challenging environments.

This presentation discusses the development and demonstrates the performance of POS/NAV technologies for crowd management monitoring the location of people in different motion modes in both indoor and outdoor environments. These technologies were designed to provide robust POS/NAV solutions utilizing multi-sensor fusion technologies. Two products will be discussed in this presentation. The first product is an integrated POS/NAV system monitoring the location of people in land vehicles integrating GPS receivers with other vehicle motions sensors and systems (accelerometers, gyroscopes, radar and vision). The system is designed to provide seamless POS/NAV solution in all environments. The second product is an indoor multi-sensor tracking that integrates accelerometers and gyroscopes from different wearable and portable devices. The tracking device was specifically designed to position without involving GPS or WLAN. The real – time positioning performance of both products will be demonstrated as part of this presentation.
