Communication establishment training with satellites using KIZUNA in a prediction of the Nankai Trough earthquake

Communication establishment training with satellites using KIZUNA in a prediction of the Nankai Trough earthquake

On July 29, 2015, JAXA and NICT offered the Internet environment with asatellite when the Japan Medical Association (JMA) conducted the “satellite use demonstration in a prediction of the Nankai Trough earthquake (Disaster preparation drill) 2015.” The communication environment was established by setting up a ground station in each JMA prefectural office under the assumption that communication lines were cut off due to a large-scale disaster. We transmitted high-definition images from a sma...

New Internet Society with Satellites
Aiming for a society where anybody can get information anytime, anywhere

"KIZUNA" (WINDS) was jointly developed by JAXA and National Institute of Information and Communications Technology (NICT), and launched by H-IIA Launch Vehicle on February 23, 2008. "KIZUNA" (WINDS) connects to the network between space and the ground, and demonstrates the technologies related to ultra-high-speed and large-volume data communications.

Characteristics of Wideband InterNetworking engineering test and Demonstration Satellite "KIZUNA" (WINDS)

KIZUNA satellite communication system uses the latest technology to create a faster, more efficient and more convenient communications environment.

KIZUNA will lead to ultra-high speed international Internet-based communications. The technology takes advantage of the fact that satellite communications are far-reaching, multicasting, and disaster-resistant. It will enable high-speed, large-volume data transmission, allowing ultra-fast domestic and international Internet-based communications, in particular between Japan and its neighboring countries in the Asia-Pacific region.

Ultra-fast satellite-based Internet-based communications will remove the so-called digital divide by providing high-speed Internet service in areas where the terrestrial communications infrastructure is poor. Among other uses, this will make possible great advances in telemedicine, which will bring high-quality medical treatment to remote areas, and in distance education, connecting students and teachers separated by great distances.
