About AST

Our Development

AST’s flow control units and pressure regulators have been successfully integrated into a wide range of electric propulsion systems, delivering reliable performance, precise control, and proven robustness.

Continuous customer feedback has shaped mature solutions for Hall Effect Thrusters, Gridded Ion Engines, HEMP Thrusters, and other electric propulsion technologies.

Building on the success of the OneWeb Constellation, AST has become a trusted supplier to leading New Space companies, providing reliable and scalable fluidic components for both prototype and series production.

AST also contributes to major institutional missions, including the European Space Agency’s Earth Return Orbiter for the Mars Sample Return mission.
