WINDS (Kizuna)
Organization:
Mission type:Comsat
[ edit]
WINDS (Wideband InterNetworking engineering test and Demonstration Satellite, also known as Kizuna), is a Japanese communication satellite, scheduled to be launched by an H-IIA carrier rocket from the Tanegashima Space Centre, no earlier than November 2007. It will be used to relay the internet to Japanese homes and buisnesses, through Ka-Band signals. It will also develop technologies to be utilised by future Japanese communication spacecraft. It is part of Japan's i-Space programme, and is to be operated by JAXA and NICT.

JAXA claim that WINDS will be able to provide 155 Mb/s download speed to home users with 45-centimetre diameter satellite dishes, whilst providing industrial users, via 5-metre diameter dishes, with 1.2 Gb/s speeds.[1]

WINDS has a launch mass of 4,850 kg, reducing to around 2,750 kg when in orbit. The spacecraft is 8 m x 3 m x 2 m in size, and its solar panels have a span of 21.5 metres. It has three-axis stabilisation, and a design life expectancy of five years.
