This paper addresses vehicle positioning, a topic whose importance has risen dramatically in the context of future autonomous driving systems. While classical methods that use GPS and/or beacon signals from network infrastructure for triangulation tend to be sensitive multi-paths and signal obstruction, our method exhibits robustness with respect such phenomena. Our approach builds on recently ...

A survey of the information sources and information fusion technologies used in the current in-car navigation systems is presented. The pros and cons of the four commonly used information sources GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information are described. Common filters to combine the information from the various sources are discussed. A prediction of po...

Inertially stabilized platforms are subject of interest for different application, e.g. telecommunications, robotics and military systems. In this paper the objective is to maintain the line-of-sight constant despite the motion of a host vehicle. The platform stabilization problem is addressed using dual-axis gyroscopic sensors, where certain vehicle dynamic constraints are considered. Sensor p...

Location is one of the most important information in the industrial world and there are many systems provide location information. GPS is the most universal positioning method. Especially, RTK(Real-Time Kinematic) algorithm is commonly used for ITS(Intelligent Transport System) precise positioning. Moreover, for the ITS, the fundamental requirement is that the positioning system can provide use...

In this paper we review the need for robust, high-accuracy positioning for path guidance in the presence of large structures (such as buildings and trees) and for the integration of sensor data. Such capability is necessary in many applications that require precision over vast areas of operation. We find that unless integrated tightly, combined INS/GPS systems diverge significantly when line of...

In November 2003, the City of Hamilton, Ontario, Canada equipped five solid waste collection trucks with Trimble Telvisant CrossCheck® GPRS 1900 Mobile data recorders. Three of the trucks are garbage packers, the fourth truck is a side-loading recycling truck, and the fifth vehicle is a 60/40-split co-collection truck equipped with a cart lifter. These trucks operated in a variety of situations...
