In November of 2018, the United States Federal Communications Commission (FCC) authorised the rocket company SpaceX, owned by the entrepreneur Elon Musk, to launch a fleet of 7,518 satellites to complete SpaceX’s ambitious scheme to provide global satellite broadband services to every corner of the Earth.

The satellites will operate at a height of approximately 210 miles, and irradiate the Earth with extremely high frequencies between 37.5 GHz and 42 GHz. This fleet will be in addition to a smaller SpaceX fleet of 4,425 satellites, already authorised earlier in the year by the FCC, which will orbit the Earth at a height of approximately 750 miles and is set to bathe us in frequencies between 12 GHz and 30 GHz. The grand total of SpaceX satellites is thus projected to reach just under 12,000.

There are at present approximately two thousand fully functioning satellites orbiting the Earth. Some beam down commercial GPS (or “SatNav”), some provide TV, some provide mobile phone services, and some bounce radar back and forth […]
