We have developed a 3D positioning system and have applied it to undulation measurement on the green during the construction of a golf course. This positioning system can quickly and precisely position and control mobile objects. It is particularly suitable for positioning construction robots over a wide area. This paper describes the fundamental structure of the 3D positioning system , the pro...

Enhanced WiFi ToF indoor positioning system with MEMS-based INS and pedometric information. Full Text Sign-In or Purchase Purchase PDF, Other Formats. WLAN is capable...

Cytokinesis is the terminal step of the cell cycle during which a mother cell divides into daughter cells. Often, the machinery of cytokinesis is positioned in such a way that daughter cells are born roughly equal in size. However, in many specialized cell types or under certain environmental conditions, the cell division machinery is placed at nonmedial positions to produce daughter cells of d...

WLAN positioning systems are a promising approach to determine a users location in In-Building environments. The motivation for developing, the possible utilization as well as known issues are discussed. Physical fundamentals and technical aspects of the WLAN technique are explained to examine the positioning potential in detail. Furthermore, an example positioning system is presented and analy...

An indoor positioning system (IPS) is defined as the network of devices which is widely used to wirelessly locate objects under the same roof using radio waves, acoustic signals, magnetic fields and other sensory information grasped by mobile devices. Reliable indoor positioning is a base for emerging indoor location based services. Bluetooth Indoor Positioning System is said to be the intersec...

Precise Point Positioning (PPP) greatly improves the precision of absolute GPS positioning by using the international GPS services (IGSs) orbit and satellite clock error products with positioning precision reaching the 1cm level [1-3]. At present, this technique has been widely applied in many engineering fields, such as mining engineering, high precise navy engineering surveying, lane surveyin...
