About
This Modified Low Power Stationary Plasma Thruster is designed for spacecraft (S/C) station keeping. Released in 2015, it boasts a guaranteed service life of 7000 hours and 7000 cycles. The thruster uses xenon as propellant and consists of anode and cathode units. It incorporates a classical magnetic system of armored type with magnetic screens. The outside diameter of the accelerating channel is 70 mm, with a mean diameter of 55 mm. The design utilizes new structural materials and components. While its nominal discharge power is 660 W, it has been forced up to 1250 W. The estimated production and delivery time is 10 months, not including material procurement (4 months) and procured parts/components (6 months). The product can be adapted to customer requirements, but currently has no flight qualification or history.
