After last year´s first achievement GIESEPP has geared up once again: A fully coupled Electric Propulsion System consisting of the RIT-10 Thruster Unit, QinetiQ´s T5-Neutralizer, AST GmbH´s Flow Control Equipment and a down-sized PPU from CRISA was brought to life. This TRL-5 demonstration has further consolidated GIESEPP´s modular approach for non-single source gridded-ion thruster solutions.
