Japan launches high-speed internet satellite Februarie 25, 2008Posted by MoshutZu in Stiri.
Japan successfully launched Saturday an experimental satellite aimed at providing high-speed Internet access across Asia, even when terrestrial infrastructure goes down, the space agency said. The domestically developed H-2A rocket carrying the Kizuna satellite was launched at 17:55 pm (0855 GMT) with no glitches from the Space Centre on Tanegashima island off the southern tip of Kyushu Island, southern Japan. The communications satellite, expected to be in use for five years, separated from the rocket approximately 35 minutes after the launch, said an official of the Japan Aerospace Exploration Agency (JAXA) during a live broadcast. The 342 million dollar-Kizuna will allow super-high speed data communications of up to 1.2 Gbps, which would make it the fastest in the world, the agency said.
That rate would translate to 150 times that of the average high-speed ADSL connection rate of 8 Mbps, or 12 times the speed of a fibre-optic communication delivery to a person’s premises (FTTP). The “Kizuna,” which also means “bond” in Japanese, is expected to begin transmitting and receiving data with terrestrial infrastructures in July after completing preparations and confirming the satellite’s safety. The satellite will enable students in Asian countries to communicate smoothly and with no time lag among one another, as if they were in the same classroom, it said. The satellite will to last five years, an agency spokeswoman said. The launch was delayed by one week after JAXA said it had discovered a problem with the gas jet thruster for its launch rocket.
