The invention provides a satellite communication device and a satellite communication method, and relates to the field of aerospace communication. The satellite communication device comprises a first communication unit, a second communication unit and a mode control unit, wherein the first communication unit performs communication in a first modulation-demodulation mode; the second communication unit performs communication in a second modulation-demodulation mode; the frequency bandwidth of the first modulation-demodulation mode is larger than that of the second modulation-demodulation mode; and the mode control unit can select communication through the first communication unit and / or the second communication unit. According to the satellite communication device and the satellite communication method, the poor anti-interference capability of satellite communication can be solved, the anti-interference capability of the satellite communication can be improved by setting a dual-communication mode with different frequency bandwidths, and occupied bandwidth and link reliability can be balanced.
Description
technical field [0001] The present application relates to the field of aerospace communication, in particular to a satellite communication device and a satellite communication method. Background technique [0002] With the rapid development of aerospace technology, the number of satellites in orbit is increasing day by day, which makes the resource occupancy rate of the space radio environment higher and higher, and the stability of satellite communication becomes worse, and the satellite may be interfered in the communication process. sexual increase. [0003] In addition, the communication between wireless devices on the ground may also cause interference to the signals sent and received by the satellite measurement and control station, making the communication between the satellite and the ground unstable and unable to cope with sudden interference events, resulting in communication failure. Contents of the invention [0004] In view of the problems of poor anti-interf...
