This paper explains a plan of research and development of high speed optical communication technology for observed data transmission from satellites/airplanes. The amounts of data acquired on observation satellites or airplanes have become larger with the rapid improvements of resolutions of sensors. In order to transmit the vast amounts of data, a communication system that combines free space optical...
In this work we first present the SATEX 1 microsatellite project, as our initial experience in space optical communications; we then describe the current activities on the design and development of the SENSAT 1 nanosatellite and especially its optical communications payload, consisting of an 830 nm downlink optical transmitter for data communications, with a 532 nm uplink as a beacon for pointing,...
The use of optical communication links is a growing and promising technology, with its applications spreading over many areas of telecommunication. ESA's involvement in the development of optical communication terminals for high data rate links between satellites already resulted in the successful demonstration of the SILEX programme using optical inter-satellite links, using the ARTEMIS satellite...
Ground-to-satellite laser communication experiments between the optical ground station located in Koganei, central Tokyo, and a low earth orbit (LEO) satellite were jointly performed by the Japan Aerospace Exploration Agency and the National Institute of Information and Communications Technology. In 18 trials during three non-consecutive months, the satellite was acquired and tracked 61 % of the time,...
