orbits in space are geometrically perfect, you can reasonably talk about 1cm accuracy there.. On earth, variations in a long list of things, including physically moving land (due to seismic activity), make "1cm accuracy" something that does not actually hold.. no doubt it has a lot of positive measuring ability .. but the real truth gets messy..
