Space Propulsion Systems for Satellites and Spacecraft

A complete range of monopropellant, bipropellant and electric ion propulsion systems.



For over half a century, we have been producing propulsion systems for a diverse range of international satellites and spacecraft. We specialise in monopropellant, bipropellant and electric ion propulsion and supply from component parts and subsystem modules, through to complete propulsion systems and beyond - with a complete range of propulsion support services from delivery, integration & test, and propellant loading, through to launch campaign support, post launch and in-orbit operations.



Typical applications of our propulsion system include:




Our bipropellant propulsion systems are mainly used on medium to heavy satellites and spacecraft such as space agency mission and for the larger platforms of commercial satellites.

Unified Propulsion Systems

For the majority of our satellite customers, the top level propulsion requirements are very similar. Namely apogee injection and attitude maneuver for transfer orbit, station keeping and orbit control, followed by deorbitation or transfer to a graveyard orbit. The Lampoldshausen team realised, early on, that the separate systems required for these different functions could be unified into a common system and what became known as the Unified Propulsion System (UPS).


The Unified Propulsion System Comprises:

Our monopropellant hydrazine propulsion systems are used for small to medium spacecraft for LEO and MEO missions. Standard of-the-shelf propulsion systems are available, as well as custom modules for satellites within the 220 kg to 2500 kg class.

We also supply Roll and Attitude Control Systems (RACS) for the upper stages of heavy and small launchers. The RACS enables roll and pitch control of the launcher after jettisoning of its solid rocket boosters. Thereafter, it is used for fine control manoeuvres and precision upper stage orientation before separation of one or more payloads.

Propulsion of the future has now become a reality with Lampoldshausen's radio-frequency ion propulsion systems providing a specific impulse ten to twenty times higher than today's best performing liquid propellant rocket engines and 30% to 50% higher than alternative ion propulsion systems.



 Electric propulsion systems offer many advantages over chemical propulsion systems, including:
