Half-duplex pseudo satellite device based on Beidou RD function and operating method thereof

The present invention belongs to the technical field of satellite navigation, and especially relates to a half-duplex pseudo satellite device based on a BeidouRD function and an operating method thereof. The half-duplex pseudo satellite device comprises an antenna unit, an RF unit, a baseband unit, a control processing unit, an RD processing and transceiving unit, a power supply unit, an internal clock, an external clock interface, and various interfaces achieving external data transmission; wherein the antenna unit is connected with the RF unit, the RF unit is connected with the baseband unit, the control processing unit is connected with the antenna unit, the RF unit, the baseband unit and the RD processing and transceiving unit, the power supply unit provides power for all parts in the half-duplex pseudo satellite device, the internal clock respectively provides clock for the control processing unit and the baseband unit, the external clock interface is connected with the RF unit and the baseband unit. The operating method of the half-duplex pseudo satellite devicecomprises three operating states, i.e., a pseudo satellite operating state, a forwarding operating state, and a monitoring state.
