Abstract
A satellite communication system communicates via a communication satellite using one of a plurality of portable station devices as a master station device and another portable station device as a slave station device. The master station device transmits a first control signal for the slave station device to establish synchronization. The master station device determines that the slave station device is in a communicable state by a second control signal received from the slave station device that has received the first control signal and established synchronization. The master station device selects one of at least one slave station devices in a communicable state and transmits a third control signal for instructing start of transmission of a communication signal to the selected slave station device and the subject device. Due to this, it is possible to connect a channel between portable station devices without the intervention of a control station device or a regulation station device.
