Developed position and direction detection system with overwhelmingly high precision than NEC and GPS
As a result of the experiment, it seems that the position detection accuracy is ± 30 cm and the direction detection accuracy is about ± 1 degree.
The accuracy of this detection is about 10 to 100 times that of GPS commonly used in car navigation systems and mobile phones in general. In the future it seems that it aims to utilize in various applications such as grasping the position of workers in factories etc. and managing stored items in warehouse. It might be quite amazing.
Details are as follows.
Development of high-accuracy position and direction detection system (January 16, 2007): Press Release | NEC
According to this release, NEC jointly collaborates with utility poles, telecommunication networks and other facilities such as Chugoku Electric Power Co., Ltd. to develop highly accurate position / He seems to have developed a system that realizes direction detection.
This system manages and controls the "mobile terminal" that provides information to a PDA (personal digital assistant) or the like, the "base station" that sends the information necessary for position and direction detection to the mobile terminal, and the base station "Base station control server", which consists of three kinds, use a general purpose radio for each communication. After setting the base stations at 7 meters intervals and carrying out experiments, it was confirmed that the position detection accuracy is about ± 30 cm and the direction detection accuracy is about ± 1 degree.
In addition, since this system communicates wirelessly between the base station control server and the base station, it is not necessary to lay out a communication line for each base station, and because general purpose radio is used, it is possible to construct an inexpensive system It has been with.
