Our existing GPS is good enough (when not jammed) for a person to drop a bomb, but not good enough for a non-person entity (NPE) to be behind the wheel of a large automobile. And you may ask yourself, “Where is that large automobile?”
“The satellite is the first of a planned constellation called Pulsar, which is being developed by California-based Xona Space Systems. The company ultimately plans to have a constellation of 258 satellites in low Earth orbit. Although these satellites will operate much like those used to create GPS, they will orbit about 12,000 miles closer to Earth’s surface, beaming down a much stronger signal that’s more accurate—and harder to jam.
“Reid and Manning began to think about how to build a space-based PNT [positioning, navigation, and timing] system that would do what GPS does but better, with accuracy of three inches (10 centimeters) or less and ironclad reliability in all sorts of challenging conditions.”
