About
This dual-mode stationary plasma thruster, released in 2007, is engineered for critical spacecraft operations such as station keeping and orbit raising to Geostationary Earth Orbit (GEO). It features two operating modes: 1.35 kW and 2.5 kW, utilizing xenon as its propellant. The thruster is composed of anode and cathode units and incorporates a classical magnetic system with magnetic screens and four external magnetic coils. Its accelerating channel has an outside diameter of 100 mm and a mean diameter of 85 mm. The plume divergence half-angle (90% of ion current) is 30°. The design benefits from new structural materials and components. While the product is not flight qualified, it offers the possibility of adaptation to customer requirements. The guaranteed service life is 8000/12000 hours and 5000 cycles, with an estimated production/delivery time of 10 months (excluding material and component procurement time).
