| titleOfInvention | Satellite communication system |
| abstract | (57) [Abstract] [Problems] Conventionally, satellite communication systems for communicating between earth stations using artificial satellites as relay stations and satellite communication systems between data relay satellites and earth stations are known. There is no known satellite communication system that enables communication between the two. SOLUTION: The lunar station 7 is installed on the earth-oriented surface of the moon by utilizing the fact that the rotation cycle and the revolution cycle of the moon are equal. As a result, since the lunar station 7 is always facing the earth, it is possible to secure communication with the earth station 5 for 24 hours. Data relay satellites 3 and 4 in geostationary orbit Are arranged at intervals of 120 degrees. The earth station 5 can secure a communication line 9 formed with the lunar station 7 via the data relay satellite 3 or 4 for 24 hours. Further, a communication line 10 is provided between the lunar vehicle 8 moving on the lunar surface or the facility on the opposite side of the earth-orientation plane and the lunar station 7 via the data relay satellite 6 in the lunar orbit. Has been established. |
