任务简介
WINDS（又称Kizuna）目前由JAXA和国家信息通信技术研究所联合开发，作为日本政府IT战略总部e-Japan优先政策计划的一部分。WINDS于2008年由H-IIA运载火箭发射，旨在建立世界上最先进的信息和电信网络。 预计该信息和电信网络的速度和容量将远超以往任何成就。WINDS卫星通信系统旨在为配备45厘米口径天线（与现有通信卫星天线尺寸相同）的家庭提供最高155 Mbps（接收）/ 6 Mbps（发送）的速度，并为配备5米天线的办公室提供超高速1.2 Gbps的传输。

WINDS, also called Kizuna, is currently under joint development by JAXA and the National Institute of Information and Communications Technology, as part of the e-Japan Priority Policy Program of the Japanese government's IT strategy headquarters. WINDS was launched by an H-IIA Launch Vehicle in 2008 to establish the world's most advanced information and telecommunications network. It is expected that this information and telecommunications network's speed and capacity will be much higher than anything achieved previously. The WINDS satellite communication system aims for a maximum speed of 155 Mbps (receiving) / 6 Mbps (transmitting) for households with 45-centimeter aperture antennas (the same size as existing Communications Satellite antennas), and ultra-fast 1.2 Gbps transmission for offices with five-meter antennas.
