What principles of general relativity are used in GPS systems?
Can you tell me about principles of general relativity used in GPS systems?
Sure. One of the most important principles of general relativity involved in GPS systems is time dilation. GPS satellites are constantly moving at high speeds and are at different distances from the Earth's center of gravity, which causes their clocks to run slower or faster than clocks on Earth. In order to ensure GPS accuracy, this time difference needs to be accounted for and corrected.
