<p>PURPOSE: A duplex device in a satellite communication system is provided to perform a role of a terminal station in a standby mode from a center of a standby mode. CONSTITUTION: Two flash memories(500,510) respectively stores a central station application program and a UE application program. An FPGA(Field Programmable Gate Array)(520) selects one among two flash memories. After CPU(Central Processing Unit)(530) controls booting through selects one among two flash memories through the FPGA, the central processing unit controls booting through an application program of the selected flash memory. A nonvolatile memory(540) stores operational data of a central station or a terminal station.</p> |
