CNES micro and mini-satellites platforms already use hydrazine propulsion subsystems. The PLEIADES satellites will also resort to hydrazine technology. For other missions in the future, CNES performs pilot projects in order to define the best technical solution to meet the needs of the mission. Regarding propulsion, hydrazine technology keeps on being valuable for different kinds of applications. After a brief description of the existing subsystems (micro and mini-satellites platforms MYRIADE and PROTEUS, PLEIADES), different examples of pilot projects for which hydrazine is necessary are given. In these examples, the role of the hydrazine propulsion subsystem goes from a complement of the ~H~FV performed by the launcher to attitude control when the main engines are electrical thrusters. Owing to these examples, we can see which values of thrust and which tank volumes are needed. Moreover, Research and Development actions, supported by the Propulsion and Pyrotechnics Department in CNES Toulouse, and which could be applied to hydrazine propulsion, are mentioned.
