Direct positioning and data acquisition system, composed of global positioning system (GPS), inertial navigation system (INS), laser ranging technique and digital photogrammetry, is a fast data acquiring technique developed in the field of surveying and mapping in recent years. Focusing on data acquisition based on vehicle-borne mobile mapping system integrated with GPS/INS/CCD cameras, this pa...

For low-cost and continuous indoor navigation, an INS/Wi-Fi (inertial navigation system/Wi-Fi) integrated system is expected to yield a synergetic effect resulting in higher navigation performance than using the standalone systems. In this paper, the authors explore the integration of Wi-Fi measurements with data from microelectromechanical systems based inertial measurement unit for indoor veh...

Many urban areas face traffic congestion. Automatic traffic management systems and congestion pricing are getting prominence in recent research. An important stage in such systems is lane prediction and on-road self-positioning. We introduce a novel problem of vehicle self-positioning which involves predicting the number of lanes on the road and localizing the vehicle within those lanes, using ...

Accurate vehicle location is essential for various applications in the field of intelligent transportation systems (ITS). Existing vehicle location systems rely on multiple positioning sensors and powerful computing devices to execute complex map matching algorithms. There exists a strong need for exploring a solution for vehicle location that relies on a GPS receiver as the sole means of posit...

In this paper, we study certain geometric and topological properties of online social networks using the concept of density and geometric vector spaces. “Moi Krug” (“My Circle”), a Russian social network that promotes the principle of the “six degrees of separation” and is positioning itself as a vehicle for professionals and recruiters seeking each others’ services, is used as a test vehicle.

The electro-mechanical actuators are used in aerospace vehicle is used for attitude control of vehicle. Actuators used in aerospace vehicle require very accurate positioning accuracy, high dynamic requirements. Hence the actuator design in aerospace vehicle is very critical and plays very important role in total performance of the vehicle. The actuators are to be designed very compactly with hi...

Comparative analysis of two algorithms for underwater vehicle positioning using measurements range to a drifting buoy and radial velocity is carried out. The based on building location contours polynomial filtering are considered. Invalid data rate RMS position error analyzed compare the algorithms. Based made, algorithm accepted as preferable.

Radio frequency identification (RFID) technology has become one of the most prosperous positioning technologies due to its advantages in non-contact and non-line-of-sight sensing. Most of the current positioning applications using RFID were implemented by setting a few RFID readers in some known locations, which were only suitable for the indoor or small area of outdoor positioning. This paper ...

With the continuous development of urbanization, number vehicles has increased year by year. In order to solve hard-to-park problem, underground garages have been built on a large scale in many cities. However, due fact that GPS signals are kept out garage, technology does not work. As consequence, drivers cannot use navigation equipment search for parking space. view this, vehicle positioning ...
