Abstract

The goal of this paper is to show the problem of the orbit determination of an artificial satellite, situated in an orbit of approximately 1,000 Km height, which has a receiver able to receive signals transmitted by a constellation of satellites placed at an altitude of approximately 20,000 Km. The constellation is made up of satellites which composes the "Global Positioning System" (GPS).
