Various types of propulsion systems are used depending on the mission characteristics, monopropellant, bipropellant and electric. Monopropellant is mainly used for low Earth orbit applications such as earth observation (SPOT program) or for minisatellites carrying scientific payloads (PROTEUS platform). Bipropellant systems which are more efficient are used for geostationary telecommunications satellites (TELECOM2, STENTOR) and can be associated to electrical propulsion for the station keeping of these platforms (STENTOR). The use of electric propulsion allows an important launch mass reduction. The future developments are mainly dedicated to the use of electric propulsion for the orbit raising of telecommunication satellites which leads to the development of thrusters with higher thrust than those existing today, the study of new propellants safer than the existing propellants (hydrazine, monomethylhydrazine,... ) and the study of new systems to pressurise the propellants.
