Generally speaking this is covered by the acronym PNT (Position, Navigation and Timing). Depending on the application it is usually one or more of these outputs that is required to be generated.

This data is usually integrated with other sensors or data to serve the desired purpose. It can be used to map existing features or topography though to being the basis for machine control in construction or the basis for timing in network synchronisation. Depending on methodology adopted, positions at the millimetre level and timing at the ten nanosecond or better are readily achievable.
