It seems strange to me that there are only 4 ground antennas that assist with GPS. Trillions of dollars of business rely on the GPS, and there are only 4 ground antennas.
Any internet or communication blackouts could also include GPS blackouts.
I'm not predicting anything. I just find it weird to have only 4 ground antennas.
Does seem weird maybe they only need one to anchor and the other three are the back ups.
