GPS devices use satellites to pinpoint a user's location by syncing the device's chip with the atomic clocks on the satellites. GPS has been used since the 1960s when the US Navy tested the first satellite constellation, and it has since become integrated into many technologies from portable GPS units to apps that allow users to geotag social media posts. Programmers can access GPS data through APIs to build location-aware applications.
