Abstract
The invention concerns a method for placing an artificial satellite on a geostationary orbit injected on said orbit by a launch vehicle. The method is characterised in that the assembly consisting of the last stage (L) of said launch vehicle and satellite (S) be injected on the geostationary orbit (G) is first directly sent on a circular orbit (C), called extinction orbit, near the geostationary orbit, but sufficiently distant therefrom to avoid possible interferene with space objects already on the geostationary orbit (G), the satellite (S) is separated from said last stage (L), which stays on said extinction orbit (C), and the satellite (S) reaches the geostationary orbit (G) from said extinction orbit (C).
