About
This Stationary Plasma Thruster (SPT) is designed for spacecraft station keeping and orbit raising, specifically to Geostationary Earth Orbit (GEO). Released in 2013, it boasts a guaranteed service life of 10,000 hours. The product is an engineering model and consists of anode and cathode units. It employs a classical magnetic system with magnetic screens and eight external magnetic coils. The thruster uses xenon as a propellant. The outside diameter of the accelerating channel is 230 mm, with a mean diameter of 200 mm. While the product is not flight qualified, there is a possibility to adapt it to customer requirements. The manufacturing lead time is estimated at 12 months, not including the time for material procurement (4 months) and procured parts and components (6 months).
