SpaceX, a space launch service provider and equipment manufacturer based in Hawthorne, California, plans to diversify its business by launching an Internet network of non geostationary satellites and ground base stations. The network, known as Starlink, eventually intends to use lasers to relay data between satellites to provide global coverage and independent operation.
However, SpaceX’s Starlink program has been reviewed by the Federal Communications Commission (FCC), which has yet to decide whether to maintain the company’s priority in certain frequency bands. Moreover, the Committee has not changed its view that Starlink is experimental in nature.
Starlink has just won a major victory from the FCC by granting SpaceX Services Inc. a temporary license to operate Starlink ground stations in six states of the United States. It is reported that SpaceX decided to submit a special temporary authorization (STA) application to the FCC in mid June this year.
in the initial stage of Starlink launch, SpaceX will have to use ground base stations to operate the network and provide users with the ability to connect to Internet servers. The company asked the FCC to allow it to temporarily run six ground stations in different states of the United States to test satellites and try to ensure that the network works as expected after commercial launch later this year.
SpaceX has now obtained approval from the FCC. The six ground stations are located in hitterdal, Minnesota; tioesta, California; robertsdale, Alabama; Baxley, Georgia; Butte, Montana; and Colburn, Idaho.
each gateway ground base station of SpaceX has eight antennas made in-house of SpaceX. The antenna size is 1.5 meters, which is 3.2 meters above the ground. The input power is 50 watts and the effective isotropic radiation power (EIRP) is 66.5 deciwatts. EIRP is an indicator of the maximum output power of the antenna in a single direction.
