Plan to launch 4000 satellites for the construction of Gigabit-class Internet network that SpaceX can use anywhere on Earth

By SpaceX

Space venture companySpaceXHas planned to launch more than 4000 satellites for building a gigabit-class Internet network using communication satellites. SpaceX in 2015I am considering building an Internet environment that can communicate not only on the earth but also on Mars using communication satellitesIt was announced that.

According to Ars Technica of the news site, SpaceX submitted an application for the satellite space station approval to the Federal Communications Commission (FCC) on November 15, 2016.

At the SpaceX event in 2015, CEO Eulon Mask said "Our concern is building a huge global communication system than what we have been told"It is suggested to build an Internet environment that can be used in space as well as everywhere on the earth, but it is clear that this plan is progressing steadily.


We already offer internet service using satelliteHughesNetHas an altitude of 35,000 kmMiddle orbitAccording to the application, SpaceX places satellites at altitude 1150 km to 1325 kmLow orbitWe plan to launch 4425 satellites to the satellite. It is stated that the launch time is around 2019.

The current satellite Internet communication has a delay of at least 600 msec due to the distance between the Earth and the communication satellite. On the other hand, by placing satellites in a low orbit closer to the Earth, the delay of the service of SpaceX is supposed to be kept to 25 msec to 35 msec like the Internet which is connected by wires It is.

According to the application, the communication capacity of the satelliteDown linkCapacity is 17 Gbps to 23 Gbps per one. Originally, 800 satellites were deployed to provide broadband connectivity in the whole country and the whole world, and if all the satellites were deployed, a true global network including the equator to both poles will be constructed. As for the communication band, it is planned to use 10 GHz to 30 GHz included in "Ku band" and "Ka band".
