> Satellites view half the globe at once. But you know that just as well as I do. They don't, because of perspective. Even satellites in Geosynchronous orbits don't see half the globe. They are above the equator but they can never see both poles at once. Satellites closer than that only see a small part of the globe. A satellite would have to be infinitely far away to see an entire hemisphere at once. A GPS satellite at 20000 km of altitude only sees 38% of the Earth. https://www.wtamu.edu/~cbaird/sq/2013/05/10/since-one-satellite-can-see-half-of-the-earth-why-do-we-need-more-than-two-satellites-in-a-given-network/ https://www.wtamu.edu/~cbaird/sq/2013/05/10/since-one-satell...
