Navigation and communication platform for on board unit of logistics traffic

Abstract

The existing theory and technology provides new means for on board system of logistics traffic. The use of navigation and communication platform will be an integral part of on board unit (OBU). Applications on OBU have been growing substantially in recent years to reduce the probability of accidents. On navigation and locating part, locating solution innovation is now driven by requirements of location based services on logistics. The fact is mass users distributing in urban canyons, indoors or in shaded areas where Global Navigation Satellite Systems (GNSS) signals can be attenuated, so the navigation platform generally need be supported by combining GNSS with wireless network and wireless sensor network. On communication part, it is necessary to establish a vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication unit beyond the consideration of the road safety. In this paper, the architecture of OBU which have an advanced navigation and communication plat are presented first. Then the fundamental location estimation combined with GNSS, 3G wireless networks and WSN is developed. Finally, the OBU semi-physical Simulation platform is developed. Navigation and communication platform in OBU for safety services is demonstrated in this paper with its seamless integration feature.
