Application of global positioning system to determination of tectonic plate movements and crustal deformations [PDF]
It is shown that pseudo-range measurements to four GPS satellites based on correlation of the pseudo random code transmissions from the satellites can be used to determine the relative position of ground stations which are separated by several hundred ...
