Green Chemical Propulsion System “EPSS”

NanoAvionics has developed TRL-7 (Technology Readiness Level) level prototype of a miniaturized, high performance, environmentally-friendly propulsion system. This system is fueled by an ADN-based mono-propellant which has up to a 6% higher specific impulse and 24% higher energy density as compared to the hydrazine employed systems, permitting significant levels of thrust to be stored within a relatively small storage volume. An ADN-based propellant is “green” and its usage contributes to ESA’s and NASA’s clean space initiatives.

The upcoming product will be scalable according to the client mission requirements, and will be compatible with the CubeSat standard also suitable for satellites below 150 kg. It will be the first complete, harmonized, plug and play propulsion system for small satellites available in the market.

Applications

  • orbital missions such as Earth Observation
  • communication
  • accurate weather forecasting
  • constellation deployment and formation flights
  • drag compensation and orbit maintenance
  • interplanetary missions and many other new small satellite applications

General Features

Components such as thruster, valves, fuel tanks and the propellant management system were designed and manufactured solely in Europe.

The developed prototype has been tested during the LituanicaSAT-2 satellite mission providing required technical information in order to reach TRL7 level and further develop a commercial product.
