Facebook is building an Observatory for laser communication with satellites

On the snow-covered top of the California mount Wilson housed many famous Observatory. For example, until 1949 it was the Hooker telescope, and in 2004 it appeared optical interferometer CHARA. At the moment, it built two new Observatory, which, although not intended for studying of space, but still will surely go down in history. The construction involved a small Tech company PointView which, note, is part of Facebook.

It is reported that the Observatory will be designed to establish laser communication with a satellite Athena. It is known that it will be used for distribution to the Internet in underdeveloped regions of the world. Earlier the company wanted to use drones Aquila, but in June 2018, the project was closed.

The company has long been interested in laser and optical methods of information transfer. She sees at least two advantages in comparison with radiofrequency method: first, they provide higher speed data transfer, and secondly — they are well protected from interference and hacking. However, there is one big disadvantage, which can greatly degrade the link — laser rays have difficulty passing through thick layers of clouds.

Details about the upcoming technology of Internet distribution is not yet divided no Facebook, no staff PointView Tech. Some information are only known from scientific articles: in particular, they mentioned the use of research results in the field of satellite and space communication to promote the project of Facebook on globalization of the Internet.

The company has already tested laser communications between earth and air, using equipment Mynaric. When transmitting data from the ground station on a small plane, the speed was more than 10 gigabits per second. It is known that the construction of Observatory on mount Wilson began in July 2018. Perhaps Facebook has been cooperating with the German firm Mynaric and is preparing for a new phase of testing.
