Abstract

The invention discloses a satellite ground station transceiver. The satellite ground station transceiver comprises an antenna module and an integration radio-frequency module; the antenna module comprises an antenna and a feed source; the integration radio-frequency module comprises a shell, a connecting portion connected with the feed source is arranged on the shell, and an intermediate-frequency receiving signal pole N, an intermediate-frequency transmitting signal pole N and a power supply pole N are further arranged on the shell; an orthomode transducer, a receiving filter, a transmitting filter, a low noise amplifier, a first frequency mixer and a second frequency mixer; the first frequency mixer is connected with the intermediate-frequency receiving signal pole N, and the second frequency mixer is connected with the intermediate-frequency transmitting signal pole N. The invention further discloses a satellite communication system. By the arrangement, convenience in upgrading and maintaining of the device is improved, and cost is lowered while the device is integrated; reliability and expandability of the system are improved, and platformization is realized.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a satellite ground station transceiver device and a satellite communication system. Background technique [0002] Satellite communication refers to the communication between two or more ground stations using artificial satellites as relay stations to forward or reflect radio signals. The satellite communication system mainly includes four components: satellite, ground master station, ground terminal, and ground satellite control center. Among them, the satellite contains a transponder, which is used to receive the signal of the ground station, amplify the small signal, mix the frequency, amplify the power, and then transmit it to the ground station; the ground satellite control center is used to monitor the status of the satellite, and monitor the orbit and attitude of the satellite. , power, etc.; the ground master station is equivalent to a HUB, on the one hand, it is co...
