Satellite
Every month more of them

Why are they there?


What they do
Most of the Satellites are SpaceX, other imaging satellites belong to a company called DigitalGlobe, and their cameras are sharp enough to capture a book on a coffee table. Flashing by for photos dozens of times a day. Spy sats can read the book itself. But at that high resolution, they can only image that book at most 12 times a day.
Another flock of satellites called Scout—can snap a photo of a high- demand spot (say the Port of Rotterdam) 40 times a day. They will be 30-centimeter class, meaning they could resolve a laptop or a TV.
10963 satellites

Where are they
Different layers in orbit. Low satellites like the satellite ‘trains’ from spaceX, at 500 Km distance from earth. Middle and high placed satellites. The frequencies they use are not always public domain. You can download a list of satellites and the frequencies they use.
Satellites can play an important role in the brainhack. For positioning of the target, for transmitting signals, or for secret communication and broadcasting.
