Stanford University's GPS Laboratory has integrated a new multiple-antenna GPS receiver with an inertial measurement unit into the DragonFly unmanned air vehicle. Recent successful flight tests have demonstrated the performance of the new avionics and illustrated the great potential to use the aircraft as a testbed for navigation and control experiments. Unmanned air vehicles (UAVs) are attract...

The United States Federal Aviation Administration (FAA) Alternative Positioning, Navigation, and Timing (APNT) program is examining the use of existing FAA terrestrial infrastructure to provide navigation capable of continuing US National Airspace System (NAS) operations should Global Navigation Satellite System (GNSS) position, navigation, and timing (PNT) services be unavailable. The approxim...

in this study, the problem of navigation in dynamic and unknown environment is investigated and a navigation method based on force field approach is suggested. it is assumed that the robot performs navigation in unknown environment and builds the map through slam procedure. since the moving objects' location and properties are unknown, they are identified and tracked by kalman filter. kalm...

Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...

With the continuous development of the industrialization process, the countries all over the world gradually appeared lack of agricultural labor force and aging phenomenon, which was especially prominent in developed countries. However the agricultural robot with high operating efficiency, high qualities of work will play an increasingly important role in future agricultural production. Robot n...

End-user friendly interface design is of tremendous importance for the success of mobile applications which are of increasing interest in the e-Business area. In this paper, we present an empirical evaluation of a mobile information system for improving navigation of public transport. High air pollution and respiratory dust, along with other threats to environmental conditions in urban areas, m...

The Federal Aviation Administration (FAA) Alternative Positioning Navigation & Timing (APNT) program is developing and examining solutions to provide terrestrial based radio-navigation capability that can support Next Generation Air Transportation System (NextGen) even with the loss of GNSS. Two technologies being examined are improved distance measuring equipment (DME) and passive ranging from...
