Einstein's general theory of relativity, which deals with gravity, could be used to improve global navigation systems in the future. ESA's Advanced Concepts Team has collaborated with the University of Ljubljana to research this possibility.
Present navigation satellite systems, such as Galileo and GPS, employ Newtonian trigonometry to determine positions, using Earth stations as reference points. This approach would perform ideally if all the satellites and the receiver were at rest and far from Earth.
These are accounted for by introducing relativistic corrections to the Newtonian theory. For a ground user, these corrections can be as large as 12 mg iiprt fst frm.
