The question is not merely one of location; it is also a matter of temporality

The accuracy of global navigation satellite system (GNSS) correction services is critical for many modern applications, such as self-driving cars, precision agriculture and robotic lawn mowers. These services improve positioning accuracy by taking into account satellite clock and orbit errors, signal bias and the effects of the ionosphere and troposphere. However, different correction service providers may use different reference frames, which can lead to biases between different positioning results for the same location.

The movement of tectonic plates has a significant impact on accurate geolocation. The Earth's surface is not static and geological plates may move a few centimetres per year, and the accumulation of such small movements over time can lead to significant positional changes. For example, the Eiffel Tower has changed position in response to the movement of the Earth's crust since it was built. This plate movement means that even high-precision mapping markers can move with it, affecting the way positions are measured.
