The GNSS Merry Go Round
The whole GNSS world should have a warm spot in its heart for centripetal forces.
After all, a centripetal force — in this case, gravity — is what keeps planets in rotation around our Sun and satellites, around the Earth.
Centrifugal force, of course, is what throws us off a merry-go-round or carousel. Centripetal force is what keeps us on board.
For those on a merry-go-round, the centripetal force is not gravity, but rather the tensile strength of our arms pulling us toward the center of rotation, at right angles to the motion of our seats.
