Abstract

PURPOSE:To simplify facilities, to improve a processing efficiency with an earth satellite and to reduce a communication cost by accumulating communication information to the earth satellite together with transmitting time information. CONSTITUTION:An earth satellite 3 to rotate on a polar orbit 2 to pass over the sky of the North Pole N and the South Pole S of the Earth 1 in the direction of an arrow is of a sun synchronous shape to revolve around the Sun together with the Earth. For example, information is transmitted from a transmitting station 4 in Tokyo toward the earth satellite 3 at a time t1. The information includes the identification information, transmitting time informtion and communication data of a receiving signal. The time information shows a time T necessary for the earth satellite 3 to move from the upward position of the transmitting station 4, for example, to the sky position of a receiving station 5 in New York. The transmitting information from the transmitting station 4 is received by a receiving antenna 6 of the earth satellite 3 and stored through a control part 7 to a memory 8 together with the receiving time t1. After a time T from the time t1, the earth satellite 3 reads the transmitting information of the memory 8 and transmits it from a transmitting antenna 10 to the receiving station 5.
