| Abstract(in English) | Satellite communications is important to various space-based activities, such as data reception from earth-observation satellites, communication links with manned space stations, and in-orbit operations of space planes. In particular, optical communication systems have various advantages over other types of communications. They have smaller and lighter equipment, higher data rates, larger communication capacities, limited risk of interference with other optical communication systems, and no licensing requirements nor tariffs. Recently, the development of small satellites are actively promoted; however, the small satellite community still uses 9.6-kbps communication links by employing ham radio communications because of resource constraints in the nano-class satellites. The compact terminal can be used in nano-class satellites that have a mass of the order of a few tens of kilograms. In addition, there is a significant advantage with regard to the frequency-licensing problems faced by satellites, and the optical frequency carrier will be very useful to the small satellite community. However, the atmospheric turbulence must be taken into account through satellite-to-ground direct laser communication links. In this paper, the link analysis under the atmospheric turbulence is discussed and the applicability to micro-satellites is described. |
