ISPTech 4U CubeSat Propulsion Module

Founders Associate at ISPTech - InSpacePropulsion Technologies

Hardthausen, Germany

About

Status

  • Demonstrator under testing


  • ‍Customer projects ongoing, IOD 2026

Your benefits

  • Green, affordable and easily available propellants: N2O + C2H6

  • Simple system architecture – self-pressurized system

  • Thrust level can be controlled by propellant temperature control

  • Thermal steady-state operation of the thruster allows significant deltaV from a single maneuver

  • Pulse mode operation allows for precise attitude control

  • ITAR free and REACH compliant

  • Cold-start capable

Capabilities

  • Main propulsion with HyNOx-1 thruster (z-direction): 0.5-2 N, depending on propellant conditions

  • 900 Ns impulse bit in one continuous firing demonstrated at DLR vacuum facilities

  • Roll, pitch and yaw via 4 attitude control thrusters with redundant thrust capability in z-direction via attitude control thrusters (supplied by independent isolation valve)

  • HYNOX-1 Thruster operatable in cold gas mode as back-up option

  • Propellant tanks can be heated
