Abstract
PURPOSE:To efficiently execute the satellite communication by forming a command for multiple address communications and executing the transmitting and receiving with a line allocation control circuit when one frequency is time- divided and the satellite communication is executed between one main station and plural slave stations. CONSTITUTION:Transmission data S-1(1)-(n) from respective slave stations are converted to a burstlike signal by ground interfaces 1(1)-1(n), multiplexed 2 and sent to a transmission signal control circuit 3. At the circuit 3, a transmission S-1 is executed through a time division multiple access device 4 onto the satellite line instructed by a control signal S-4 of a line allocation control circuit 7. A receiving signal S-2 from the satellite is sent through the time division multiple access device 4 and a receiving signal control circuit 5 to a receiving signal separating circuit 6. The separating circuit 6 is separated by a signal S-7 from a line allocation control circuit 7, and sent through the ground interface circuits 1(1)-1(n) to a designated slave station. The allocation control circuit 7 selects a necessary slave station only. Thus, a multiple address is made efficient.
