FCC tells SpaceX it can deploy up to 11,943 broadband satellites

Posted by in category: satellites

SpaceX today received US approval to deploy 7,518 broadband satellites, in addition to the 4,425 satellites that were approved eight months ago.

The Federal Communications Commission voted to let SpaceX launch 4,425 low-Earth orbit satellites in March of this year. SpaceX separately sought approval for 7,518 satellites operating even closer to the ground, saying that these will boost capacity and reduce latency in heavily populated areas. That amounts to 11,943 satellites in total for SpaceX’s Starlink broadband service.

SpaceX “proposes to add a very-low Earth orbit (VLEO) NGSO [non-geostationary satellite orbit] constellation, consisting of 7,518 satellites operating at altitudes from 335km to 346km,” the FCC said in the draft of the order that it approved unanimously today. The newly approved satellites would use frequencies between 37.5 and 42GHz for space-to-Earth transmissions and frequencies between 47.2 and 51.4GHz for Earth-to-space transmissions, the FCC said.

This Is How The Genius Elon Musk Will Give Free WiFi To The Entire Planet

Posted by in categories: Elon Musk, internet, satellites, sustainability

The very same guy, who invented PayPal, created the Tesla Cars, plans to create “SolarCities” and developed cars that will make money for you when you don’t use them, has ANOTHER brilliant idea. Elon Musk plans to launch 4,000 low-orbit satellites in order to give free internet access worldwide, two of them has already been launched a month ago.

Quantum ‘compass’ could allow navigation without relying on satellites

Posted by in categories: quantum physics, satellites

The UK’s first quantum accelerometer for navigation has been demonstrated by a team from Imperial College London and M Squared.

Most navigation today relies on a system (GNSS), such as GPS, which sends and receives signals from satellites orbiting the Earth. The is a self-contained system that does not rely on any external signals.

There’s a region over South America where NASA shuts down its satellites

Posted by in category: satellites

It’s called the South Atlantic Anomaly.


The closest radiation belt to Earth roams above South America. It is called the South Atlantic Anomaly and gives off high levels of radiation that has been known to destroy satellites.
