Abstract

In the context of investigations for a suitable attitude control thruster for future scientific space missions like LISA, or optical interferometrically coupled constellations, we have developed a thruster test facility which consists of a highly precise thrust balance coupled with plasma diagnostics. The setup allows a concurrent operation of all instruments and can also be used for different types of μN propulsion systems including cold gas thrusters. Especially, our unique double pendulum thrust balance design allows a highly accurate characterisation of micro-Newton thruster. The Balance has a proven resolution of less than 0.1 μN in bandwidth between 1Hz and 10 −3 Hz. We will give an overview of the current status of our experimentally performed micro-HEMPT development. Furthermore, the design, the present performance, and the future plans of the micro Newton thruster test facility will be presented.
