Nation-wide RTK-GPS based on FKP method and applications for human navigation and location based services

A high accuracy positioning service named PAS, based on nationwide RTK-GPS and FKP method, has been realized in Japan, and commercially operated since September 2003. Cm-level accuracy is obtained and uniformity in the service area is also validated. Application to a human navigation prototype system is also shown with a real image on a cellular telephone, and will be linked to the PAS system to serve as a location base service in the near future

A multiple terminal synchronous display method for ultra-high resolution display systems

In amusement applications, the big display device which is bigger than 100 inches that can show over 8K resolutions is required. But such devices are very expensive or not yet exist. We have developed a technology for realizing a large screen by synchronizing the time of multiple terminals connected with each display. In addition to time synchronization between terminals, we propose a technology to predict the occurrence timing of the vertical synchronization signals (V-Sync) of each terminal and start the rendering process. By using this method, it could be 0.5 frame less than the displacement of the drawing between displays. Thus, an ultra-high resolution display system with a large screen at a low cost by using a multi-display is realized.
