Gps and relativity: an engineering overview
WebApr 13, 2024 · What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping... WebDec 6, 2015 · General Relativity predicts that clocks go slower in a higher gravitational field. That is the clock aboard the GPS satellites "clicks" faster than the clock down on Earth. Also, Special Relativity predicts that a moving clock is slower than the stationary one.

The GPS network realises a coordinate time, a system of self-consistent time markers by which we label the events. This definition of GPS time requires a locally inertial coordinate system.
WebSpecial relativity predicts that as the velocity of an object increases (in a given frame), its time slows down (as measured in that frame). For instance, the frequency of the atomic clocks moving at GPS orbital speeds will tick … WebThis is how GPS works already. 4 (at minimum) satellites are required, and they solve the 4 variables of the receiver's x,y and z positions as well as the receiver's clock bias (from a mathematical perspective, this makes the receiver clock unnecessary. But it provides a useful starting point for the solution, which is generally iterative).
