MEPS (Micro-Satellite Electric Propulsion System) is a three year programme started in 2013, jointly supported by the European Space Agency (ESA) and the Israeli Space Agency (ISA) and aimed at the qualification of a propulsion system based on a low power, low cost Hall Effect Thruster (nominal power level 200W).

The system consists of a dual thruster/cathode subsystem, a power processing unit, propellant management assembly, feeding lines and a suitable Xe tank and
is conceived as a 'plug and play' system that can be easily installed on a number of small space platforms. It is intended to provide a prompt, effective response to the market needs, where small platforms can highly benefit from a low-cost, low-mass propulsion system. A suitable solution for drag compensation, orbit maintenance, end-of-life deorbiting and the exploitation of the lower layers of the LEO region, MEPS is going to pave the way to a new class of affordable and capable small space missions

Eligos Inc is an American company dedicated to bringing to the satellite market the next generation of Electric Propulsion technologies.

We are applying Plasma Science coming from particle accelerators and thermonuclear fusion research to offer the best propulsion system for tomorrow satellites and spacecrafts.

ELIGOS holds an exclusive license on the E-IMPAcT technology a radical departure from legacy Electric Propulsion technologies by not requiring any electrode or neutralizer hence being fundamentally immune to short-circuiting or cathode failure. This technology has not been analyzed throughly analyzed in theory, an extensive design effort has allowed to produce a first engineering demonstrator. This first thruster demonstrator was successfully tested in Princeton University Electric Propulsion and Plasma Dynamic Laboratory.

The Elwing Company conceives, designs, develops, manufactures and markets advanced propulsion systems for satellites.

It designs and commercializes Electric Propulsion (EP) systems for satellites and spacecraft.
Based on an innovative electrodeless plasma thruster technology – The E-IMPAcT technology (Electrodeless-Ionization Magnetized-Ponderomotive Acceleration Thruster), our propulsion systems are designed to fulfill the propulsion needs of most spacecraft operators & manufacturers in the United States and throughout the world.

Established in 2002, The Elwing Company is privately held and has offices, affiliates and subsidiaries throughout the U.S. and in Europe. It developed and holds exclusive rights on the electrodeless plasma thruster technology.
