About ION-X

ION-X is a pioneering startup in the field of small satellite propulsion systems. The company's patented technology, an ionic liquid electrospray thruster, is set to revolutionize the rapidly growing small satellites market. These satellites, which are expected to increase significantly in the next decade, are used for various purposes such as communication, earth observation, climate monitoring, and military needs. ION-X's propulsion systems are designed to optimize the utilization and lifespan of these satellites in Low Earth Orbit.

Read full description

The company's technology works by using a high-voltage electric potential to form a Taylor cone, which triggers the extraction of charged particles from the ionic liquid. These particles are then ejected at high speed to provide thrust. The system is simple, efficient, and powerful, offering unmatched thrust and fuel efficiency. It also allows satellite operators to adjust the thrust and efficiency in real time based on the required orbital maneuvers.

ION-X's business model revolves around the development and marketing of these propulsion systems. The company is currently developing a 1U plug-and-play thruster, which is expected to hit the market by mid-2024. This product is designed to be non-toxic and non-pressurized, making it safe and easy to operate. It is also well-suited for end-of-life management or debris avoidance maneuvers, further enhancing its value proposition.

ION-X's target market includes satellite operators and constellation projects. The company's competitive advantage lies in its cost-effective production and manufacturing processes, which are compatible with at-scale roll-out. This allows ION-X to offer competitive lead times, making it an attractive choice for clients.
