ISPTech

ISPTech (InSpacePropulsion Technologies GmbH) is a German deep-tech company specializing in green in-space propulsion systems for the NewSpace age. Founded by propulsion veterans from the German Aerospace Center (DLR), the company leverages over 10 years of R&D and 40 years of combined experience to deliver robust, cost-effective, and quickly available propulsion solutions for satellites ranging from CubeSats to large spacecraft.

The company flagship technology, HyNOx, uses nitrous oxide and ethane as a self-pressurizing bipropellant combination, eliminating the need for external pressurization and enabling high propellant storage densities and specific impulses of up to 300 seconds in vacuum. The HyNOx thruster family spans thrust classes from 0.5 N to 400 N, covering missions from small CubeSats to large operational satellites.

ISPTech also develops HIP_11, an advanced high-performance propellant combining hydrogen peroxide and ionic liquid fuel. HIP_11 offers specific impulses up to 310 seconds in vacuum and storage densities competitive with conventional hypergolics, making it suitable for performance-driven large spacecraft.

Headquartered in Ludwigsburg, Germany, ISPTech serves commercial NewSpace customers worldwide with flight-ready thrusters, complete propulsion modules, and custom propulsion system integration. The company products are validated through thousands of test firings and are qualified for customer projects.
