This is like from dial-up to broadband upgrade.&quot

according to the Xinhua News Agency Washington cheapjerseys.com on 6 June, (reporter Lin Xiaochun) the Broadband Era space is coming? 6 NASA announced, cheapjerseys.us the agency uses a laser beam to a high-definition video transmission from the international space station to the ground, the successful completion of a fundamental change of future space communication technology demonstration.

this communication test called "optical loading laser communication science" (OPALS). According to NASA news release, technology demonstration in 5 days, a long time of 37 seconds, known as the "Hello, world!" HD video, only took 3.5 seconds back, is equivalent to a transmission rate of 50000000000000 per second, while the traditional technology download need at least 10 minutes.

according to NASA, OPALS uses extremely small laser beam transmission data rate, compared to existing communication radio based on the improved 10 times to 1000 times. "This is like from dial-up to broadband upgrade." Responsible for the project engineer Bogdan · Vahid said.

A great challenge to

the test was "extremely accurate" lock Cheap NBA Jerseys the ground stations located American California town Wright Wood. NASA says, because of the space station 400 km away from the ground, the running speed is high, this task "is in the 9 meters away, to walk with a Cheap Beanies laser pointer always aim at a certain root hair tip".

technology demonstration in 5 days, the ground station first aim at the space station transmits a laser pointer, and then is locked on the space station OPALS system, and then start to transmit video, the whole test was carried out in 148 seconds.

OPALS Project Manager Matt · Abraham Sen said in a statement, "we look forward to continuing the OPALS test over the next few months, hope to bring light Cheap NHL Jerseys communication ability in our work for future deep space missions."
