SpaceX is going to build 1 million ground satellite stations as part of the Starlink project

SpaceX Company has filed an application with the FederalThe US Communications Commission (FCC), which describes a plan to build a non-terrestrial infrastructure for its Starlink satellite network, reports the GeekWire portal with reference to the relevant documents. According to the information in these documents, SpaceX is going to build 1 million ground stations. They are planned to be used to receive a signal from a grouping of 12,000 spacecraft orbiting satellites, half of which are planned to be deployed already by 2024.

The ground infrastructure instrument document wasfiled with the FCC subsidiary of SpaceX Services. It contains a minimum of details, but nevertheless reveals some aspects. The company promises that ground stations will be based on "advanced technologies" that will improve the quality of broadband access. It is also indicated that SpaceX plans to use flat antennas with a phased antenna array operating in the Ku-band to transmit signals between ground stations and the satellite constellation.

The application states that the standards setFCC for most antennas should not extend to SpaceX designs. Earlier, the agency has already recognized that the current regulatory standards are designed for satellite constellations located in geostationary orbit, and the company plans to bring the vehicles to low earth orbit.

Last November, Hi-News.ru reported that the company Ilona Musk received permission to launch the entire planned group of Starlink satellites. The first batch of satellites, consisting of 4425 vehicles, is planned to be placed at an altitude of 1110-1325 kilometers above the Earth's surface. The second will be placed at an altitude of 335-346 kilometers. Such an arrangement will reduce the service life of satellites, but will reduce delays in the transmission of a signal, the company believes. The first two experimental devices, which will become part of the future Starlink satellite constellation, were launched by the company into Earth orbit last year.

A document submitted to the FCC also states thatground stations for transmitting satellite signals are planned to be located throughout the United States, including Alaska and Hawaii. Also, the points will be located in Puerto Rico and the Virgin Islands.

Earlier, the head of SpaceX, Ilon Musk, saidthat the main goal of the Starlink project is to provide high-speed, reliable and affordable broadband data services to not only US residents, but the entire world. According to current estimates, more than 3.8 billion people in the world do not have Internet access. It is expected that Starlink connection speed even in the most remote regions will reach up to 1 Gb / s.

Last October, experts fromMassachusetts Institute of Technology (MIT) assessed SpaceX plans, recognizing that one of the most difficult elements of the project will be the construction of ground stations.

"SpaceX will require a large number of satellite communications stations in order for the system to operate at full capacity," the conclusion said.

When four years ago Musk first voiced the ideaStarlink, he said that the income from this enterprise will allow recouping some of the more ambitious projects of the company, including the creation of the first Martian colony.

The estimated satellite projectInternet Starlink SpaceX will cost about $ 10 billion, but by the mid-2020s, these costs should pay off. According to internal documents, satellites for the distribution of the Internet will become the main source of profits for SpaceX, and the annual revenue from Starlink will reach 30 billion dollars. Last year, Mask dismissed at least seven employees of important project managers for failing to meet deadlines. Starlink.
