GPS Satellites not only allow all Cell phones to work they also keep you safe flying in jets so they don't crash into each other

It started with American jet fighter planes crashing into each other because the North Pole (magnetic north) is simply moving too fast for accuracy in flying. So, they invented Global Positioning satellites so fighter jets stopped crashing into each other so much and this also helped keep passenger jets from not crashing into each other too. But, the real interesting thing to me isn't just global positioning Satellites it is the ever increasing speed of magnetic North and magnetic South poles moving. So, Why are they moving so fast now that we need GPS Satellites for cars and ships and planes? They have been speeding up faster and faster since the early 1900s.
