Abstract

Tohoku University (TU) in Sendai Japan and the Siberian Branch of the Russian Academy of Science (SBRAS) in Novosibirsk Russia are jointly co-work study of academic exchange program. One of the main themes is to build the NOAA Image Database by using data received in Siberia because there is about 5,000 km distance between them. To send NOAA data on real-time, we have together constructed the direct computer network named VSAT system between Novosibirsk and Sendai by using Russian communication satellite in 1998. The speed of data transfer is 64kbps each other. This system automatically receives NOAA data in Novosibirsk and automatically sends them after compression. We report the results of the communication system for transferring data; The efficiency of the network: operating ratio is 90% or more through one year. The stability: stable except changing satellite. The speed: 30 minutes even if long per scene. There are Siberian NOAA Image Database and Mongolian NOAA Image Database as a database using VSAT system. The number of access in 2000 of Siberian NOAA Image Database was about 46,000 cases, and that of Mongolian NOAA Image Database was about 17,000 cases.
