Abstract :
National Police Agency of Japan-NPA-has established Satellite Communication System all over Japan and is operating it. This system supplies services such as not only the satellite telephone, but also the video transmission in a high-resolution mode, in addition, the communication of high-speed computer data to all police organizations in Japan. The main reason of building the system is to promote the quality of police service in various fields. We have installed fixed type satellite communication sets, mobile type sets and a portable type set. When some cases happened, we bring them to the spots, and send images, voices and data to NPA and the Prefectural Police Headquarters-PPH. The system enables commanders to manage police activities from remote places because they can grasp the circumstances with the information transmitted. In this paper, I describe some characteristics of this system and explain some examples for the effective usage
