Abstract

A satellite position/arrival-time calculating section calculates the arrival in date and time at which a communication satellite is to arrive a communicable area where the communication satellite can communicate with a satellite communication terminal apparatus, and creates communicable date and time information. A timer controls a power supply control circuit in accordance with the arrival date and time information created by the satellite position/arrival-time calculating section. The timer automatically controls the power supply control circuit so as to supply communication power to a satellite communication circuit section while the communication satellite is in the communicable area and so as to stop the supply of the communication power at the time when the communication satellite leaves the communicable area.
