Does the GPS System Rely upon Einstein’s Relativity?
A large scale overview of GPS system operation is provided and the process of achieving a navigation solution is explained. The process is based on classical physics.
The one instance where a prediction of General Relativity appears to be realized is shown to actually not depend upon General Relativity. A closed loop feedback control system approach is shown to provide the error detection and correction that produces the high accuracy of the GPS system, without reliance on Einstein’s relativity.
