A principal positioning system for the Earth
Bartolomé Coll
Abstract
The project SYPOR wishes to use the global navigation satellite system GALILEO as an autonomous relativistic positioning system for the Earth. Motivations and a sketch of the basic concepts underlying the project are presented. For non geodetic (perturbed) satellites, a two-dimensional example describes how the dynamics of the constellation of satellites and that of the users may be deduced from the knowledge of the dynamics of only one of the satellites during a partial interval.
