After a test campaign conducted in New Zealand since 2013, the Google project Loon will take another major step. Sri Lanka has just given the green light to Google for it offers Internet access to all its entire territory. Google will be able to start throwing his balloons to attack the Sri Lankan skies to serve a population of 20 million. A technological challenge for Mike Cassidy, the project manager, who will have to prove that his team patiently developed since 2011 as part of the Google X labs
If the island is small, the challenge of the project is immense Google Loon
With its 65,610 km2, Sri Lanka is the 120th country by area. It ‘remains a challenge for the team of Loon project. Each balloon is theoretically capable of serving an area within a circle of radius of 20 km. So we have to Google to launch hundreds of balloons over Sri Lanka to provide Internet access for all. Problem, a balloon has a longer lifespan than a hundred days. This is already a record for it is known that the stratospheric balloon usually have a life span of a few days at most. It is therefore constantly as new balls will have to be launched and the wreckage of end of life balloons recovered.
Another key issue for the success of the project, piloting balloons. These stationed in the stratosphere at 20,000 meters, will be well above the air traffic. By cons, at such altitude where winds blow, you can not hold them in stationary flight. These hundreds of balloons will be constantly moving over Sri Lanka as they have no means of propulsion. Mike Cassidy’s team has designed a device that will allow change altitude balloons to fetch winds will bring them over their coverage area, the way the pilot his balloonist balloon. Each flask was equipped with a pump. To go down, the pump will empty the ball from one of its helium, to go up, the pump will inject the gas. It is therefore an endless stream of hundreds of balloons that will come and go over Sri Lanka. Is that such a device could offer a rate equivalent to 3G completeness of Sri Lanka and throughout the territory?
