An optical device has a reflecting mirror using a particle-dispersed silicon material including silicon carbide and silicon. The reflecting mirror includes a plurality of segments joined to each other by reaction sintering. Producing the segments is easy in comparison with that of a reflecting mirror of one piece. Accordingly, it is possible to reduce probability of breakage of the segments and to shorten process time of production of a reflecting mirror.

An artificial satellite receives a broadcast signal transmitted from a broadcast transmitter. The broadcast signal is relayed towards earth by the artificial satellite. On-earth stations receive the broadcast signal. The artificial satellite receives response signals, to the broadcast signal, from the on-earth stations, respectively. Each response signal includes at least position data of the respective on-earth station. The response signals from the on-earth stations are evaluated to generate both a local and wide-area weather forecast. The artificial satellite distributes the local and wide-area weather forecast towards the earth. Each response signal may also include an amount of attenuation caused between the artificial satellite and each on-earth station, respectively.
