FCC approves SpaceX's NGSO Satellite System

The FCC voted authorized SpaceX to construct, deploy, and operate a proposed non-geostationary orbit (NGSO) satellite system comprising 4,425 satellites for the provision of fixed-satellite service (FSS) around the world. 

In July 2016, OneWeb was granted approval to build a similar constellation of MEO satellites.

Two months ago, SpaceX successfully launched the Low Earth Orbit (LEO) PAZ observation satellite on behalf of Hisdesat and two satellites of its own.  Tintin A & B are the first two demonstration satellites for SpaceX's planned Starlink broadband satellite service. Both were successfully deployed into polar orbit and are communicating with Earth stations.

In regulatory filing, SpaceX has revealed that its initial system will consist of 4,425 satellites operating in 83 orbital planes (at altitudes ranging from 1,110 km to 1,325 km).  The system will require associated ground control facilities, gateway earth stations, and end-user earth stations. The system will use Ka- and Ku-Band spectrum.  SpaceX has separately filed for authority to operate in the V-Band, where the company has proposed an additional constellation of 7,500 satellites operating even closer to Earth. To implement the system, SpaceX will utilise the availability of significantly more powerful computing and software capabilities.  On the launch broadcast for the PAZ satellite, SpaceX said quite a bit of development work remains ahead on its satellite constellation plans.
