PROBLEM TO BE SOLVED: To obtain a satellite communication device, using a moving satellite, which evade a state wherein a communication should be interrupted so as to avoid interference even when the moving satellite is positioned in the same direction with an existent radio station such as a ground radio station. SOLUTION: This device is provided with 1st transmission and reception systems 1 and 11 for ordinary bands and 2nd transmission and reception systems 2 and 12 for bands except the frequency bands of existent radio stations and when the moving satellite is positioned in the same direction with an existent radio station, switching is so performed as to use the 2nd transmission and reception system 2 and 12. Namely, when a receiving antenna has the same directivity with the radio station of another radio communication device, a reception switching device, 5 switches the reception system to the reception system 2 by using an antenna controller 3, a channel controller 4, and a switch 60. The reception system 2 receives signals except the frequency bands that other radio communication devices are using to remove interference caused by signals from other radio communication devices. |
