1. A system for positioning a terrestrial user, said system comprising:
- a first plurality of navigation satellites placed in medium altitude orbits; and
a second plurality of management satellites placed in high orbits, able to at least partially manage said navigation satellites and to communicate with the Earth, wherein;
said second plurality comprises a set of at least three management satellites each placed in a high orbit, whose plane is inclined with respect to the plane of the terrestrial equator and cuts the latter along a diametral straight intersection line with respect to the Earth; and
the two external diametral straight intersection lines make between themselves an angle of longitude at least equal to 90°

Abstract
Disclosed is a system for positioning a terrestrial user. The system includes navigation satellites placed in medium altitude orbits, management satellites placed in high orbits, able to manage the navigation satellites and communicate with the Earth. The management satellites can include a set of at least three management satellites each placed in a high orbit, having a plane that is inclined with respect to the plane of the terrestrial equator and cuts the equator along a diametral straight intersection line with respect to the Earth. Two external diametral straight intersection lines can form an angle of longitude of at least 90 degrees.
