ROBUST

REGULUS-50 technology derives from the Magnetic Enhanced Plasma Thruster technology. The absence of electrodes, neutralizer, grids, and any component subjected to deterioration, results in an increased system simplicity, making REGULUS suitable for high Total Delta-V missions.

CUSTOMIZABLE

Different total impulses can be provided under specific customer requests, varying the tank size and thus the overall volume of the propulsion unit. The system is designed to work with Iodine, but other gases (e.g., Xenon, Argon, and CO2) can be used to meet customer needs.
