ISPTech, a German space tech company, has announced a €5.5 million seed funding round. The goal is to accelerate the development and deployment of its non-toxic propulsion systems, designed to enable faster and more agile in-orbit maneuvering.

More agile and safer space propulsion

ISPTech's propulsion systems aim to meet the needs of a rapidly evolving sector, where satellite constellations are becoming denser and missions more complex. The ability to reliably change orbits and avoid collisions has become crucial. At the same time, regulatory pressure is growing to phase out toxic propellants such as hydrazine.

Non-toxic alternatives

ISPTech is positioning itself as a provider of alternative solutions, developing spaceflight-ready propulsion systems. These include the HyNOx and HIP_11 systems, presented as non-toxic alternatives for agile in-orbit maneuvers, suitable for different classes of spacecraft. The company is preparing two customer missions and plans to launch its first mission with a small satellite equipped with ISPTech propulsion in 2026. The development of HIP_11 and orbital refueling is supported by ESA-backed projects.

Long-term goals

ISPTech's long-term goal is to improve the mobility of spacecraft, enabling more flexible satellite operations and in-orbit services. This funding represents an important step towards achieving that goal.
