Two activities, (1) orbit prediction correction using optical observation and (2) detection of the earth laser beacon by the radiometer, are described.Abstract:
Some experimental results for detection of a ground-based laser beacon by a geosynchronous satellite are reported. A 50-cm diam telescope and silicon intensifier tube camera were used for optical observation of the satellite. The transmitted argon laser beam was detected by the visible channel of a radiometer on board the Japanese Geostationary Meteorological Satellite. Two activities, (1) orbit prediction correction using optical observation and (2) detection of the earth laser beacon by the radiometer, are described.read more

Yoshinori Arimoto,Morio Toyoshima,Masahiro Toyoda,Tetsuo Takahashi,Motokazu Shikatani,Kenichi Araki +5 more
TL;DR: In this article, the most recent result of the laser communication experiment using ETS-VI satellite is presented. But the satellite failed into geostationary orbit and it is currently in a high elliptic three-day recurrent orbit, but from December 1994, we have performed laser transmission experiment for both uplink and downlink.

Nondiffracting narrow light beam with small atmospheric turbulence-influenced propagation.
TL;DR: Results show that the newly proposed long-range nondiffracting beam (LRNB) is much less influenced by atmospheric turbulence than other beams and suggest that the LRNB can apply to many fields.
