What we do

ENPULSION GmbH is a space tech company based in Austria. Founded in 2016, it has quickly become a dominant player in the space industry selling one of the most advanced propulsion solutions for small sats to a large number of worldwide satellite platform integrators. Our unique modular solutions offer to satellite manufacturers high performance at a low cost, enabling the exploration of the Solar System and the democratization of space. ENPULSION is thus positioned at the very heart of the New Space era.

Production. Means. Perfection.

ENPULSION has successfully introduced a high rate production of a high-performance electric propulsion technology. Based on value stream analysis, a scalable production line design has been implemented that scales to mega constellation production rates. Our product lifecycle philosophy is based on the agility of lean manufacturing combined with heritage quality processes. The final result is a high customer value in terms of product performance, cost reduction and short cycle times.

In December 2019 ENPULSION’s management system was awarded the ISO 9001:2015 certification as a further proof of our commitment to quality without compromises and to the constant improvement of
products and processes.

100% incoming inspection of all mechanical parts

100% traceability of all parts, manufacturing, and testing

Lean Production (KANBAN) for high throughput

Batch testing on part, component, and system-level

100% functional acceptance testing of all outgoing thrusters

Where we come from.

The ENPULSION NANO uses the FEEP technology developed by FOTEC for more than 30 years. The positive ions emitted by the ion emitters have been used to control the electrostatic potential of a spacecraft or as primary ion source for secondary ion spectrometry on numerous space missions.


It all started in

AIT starts to develop Liquid Metal Ion Sources
AIT starts to develop Liquid Metal Ion Sources

At the Austrian Institute of Technology (AIT), the first Liquid Metal Ion Sources are developed, producing a precice beam of high energy Indium ions.


More than 120 Liquid Metal Ion Sources (LMIS) operated in space for a total of more than 20.000 h.

    CEO & Founder

    Alexander Reissner started his career in the space business with RUAG Space, working in Thermal Hardware and later in Mechanical Engineering on projects like Sentinel or Bepi Colombo. He then joined the Austrian Institute of Technology and became the Team Leader for Electric Propulsion Systems. In 2013, he became the head of the Department of Aerospace Engineering shortly after it was moved to FOTEC. After growing this department from 5 to 17 scientists and engineers, he realized the potential of the FEEP technology in the SmallSat market and founded ENPULSION. His education took him from a Dipl.Ing. (MSc) in Physics at the Technical University of Vienna to the Korean Advanced Institute of Science and Technology (KAIST) in South Korea where he started a PhD program in Aerospace Engineering. He then followed his supervisor to the Technical University of Dresden where he finished his PhD Program. Alexander Reissner was also appointed to be the General Chair of the International Electric Propulsion Conference (IEPC) in 2019, which took place in Vienna.

    CHRO & Co-Founder

    Thomas likes to make sure everything works smoothly, efficiently and he is always ready to solve a problem. He has a master’s degree in political science as well as specialized higher education in international business communications. He is additionally an ISO/IEC certified trainer and safety chancellor. Thomas brings to ENPULSION over ten years of work experience in project and general operations management. He has previously worked at the University of Vienna, the Vienna Chamber of Labor, and most recently at Casinos Austria, a worldwide, leading player in the global gaming industry. When he is not helping ENPULSION to thrive and reach its fullest potential, Thomas enjoys traveling, strolling through his home town Vienna, and grilling the perfect steak on his terrace!


    David is a Research Associate at MIT (Massachusetts Institute of Technology) and avid traveller. He received his M.S. in applied physics in 2008, and Ph.D. in mechanical engineering in 2012 from Vienna University of Technology, Austria, and a M.A. in political science in 2012 from University of Vienna. Before joining ENPULSION, he was Research Scientist in the Department of Aeronautics and Astronautics working on the design and characterization of micromachined ionic liquid electrospray thrusters, which include multiple flight experiments. Before joining MIT's Space Propulsion Laboratory, he embarked on trip across the world, writing post-doc grant proposals along the way; secretly it was for beaches and sun. Aside from some teaching, he was previously working on the development of various types of electric and chemical propulsion systems. He worked on chemical green bi-propellant thrusters for small satellites and pulsed plasma thrusters for CubeSats at FOTEC and the Austrian Institute of Technology.
