Elon Musk posted his first Twitter post via Starlink


Deployment of the project's orbiting satellite networkSpacelink's Starlink is moving to a whole new level. An indefatigable engineer, businessman and billionaire, Ilon Musk, by his own example, proved the operability of satellites already put into orbit by sending a message to Twitter saying that it is delivered via the Starlink system. Almost following, he sent a second message in which he sincerely rejoiced at the system’s performance. “Wow, it works!” Musk wrote.

Internet initiative aroundThe world is based on the use of small Starlink satellites equipped with transmitters with phased array antennas with the support of directional diagram formation technology for communication with ground stations. In the spring of this year, SpaceX received a license from the US FCC regulator (Federal Communications Commission) to host more than one million ground-based terminal stations throughout the country that receive signals in the frequency range 10.7-12.7 GHz and transmit 14-14.5 GHz band. As a result, SpaceX engineers plan to provide data from each ground terminal to the network at speeds up to one gigabit per second.


Starlink project to launch onthe orbit of a group of 12 thousand satellites, launched in 2015. The first practical results were achieved in February 2018, when the first two satellites Tintin-A and Tintin-B were put into orbit in test mode. At the end of May 2019, the first batch of 60 Starlink satellites was launched into space, the flight of which led to numerous curious cases among amateur astronomers engaged in the search for UFOs.

Not everything went smoothly with the technical phase of the flightfirst grouping. Several satellites failed, and one began an uncontrolled descent along the orbit of the European satellite Aeolus, which had to change its path to prevent a collision.

In October, SpaceX has scheduled the launch of a secondbatch of 60 Starlink satellites, and in November the next group will fly into orbit. The regulator also requested permission to launch 30 thousand Starlink satellites. According to the Mask, in order to ensure minimum coverage, it is necessary to have a constellation of 420 satellites in space, and 780 satellites will ensure the normal operation of the network. Such a “squadron” can be formed by making 12 launches.

The price of the issue, according to SpaceX, forfull implementation of the Starlink project is about $ 10 billion, but in the first year of operation, revenue can reach about $ 30 billion. SpaceX's plans include the formation of a workable group by the mid-2020s.
