EXTERNAL BATTERY AND SATELLITE COMMUNICATION TERMINAL

摘要

The purpose of the present invention is to achieve satellite communication with a commonly available mobile telephone in a situation where a large number of users communicate at the same time, such as when a disaster has occurred. An external battery (20) for charging a mobile phone (10) is made to hold a satellite antenna (22) for performing satellite communication via a satellite communication link, and a satellite communication unit (24) that causes the mobile telephone (10) to perform satellite communication via the satellite antenna (22). By connecting the mobile telephone (10) and the external battery (20) with a cable (30) or the like, a satellite communication terminal (100) is configured.
