The NanoAvionics Propulsion System EPSS C1.5 is a monopropellant propulsion system with a modular design and ADN-based green propellant. The system is designed for small satellites with a compatibility to CubeSats.
The scalability can be achieved through adjusting the tank volume to accommodate different quantity of propellant. Components such as valves, fuel tanks, propellant management system, and high-performance thrusters were designed, manufactured and supplied by NanoAvionics’ partners.
- Constellation deployment and formation flights
- Drag compensation and orbit maintenance
- Orbital maneuvering, including Hohmann transfer
- Synchronization and positioning of communication equipment and payload instruments
- De-orbiting at the end of the mission and other functions
- ADN-based monopropellant
- Modular in design
- High thrust-to-volume-to-weight ratio at very low power budget
- Safety features
- Thruster catalyst heater protections
- Propellant tank temperature control protections
- Solenoid valve protections
- Firing-state protections
The system has achieved flight heritage. The operation and functionality of the system were tested and validated during orbital flight on-board the LituanicaSAT-2, 3U CubeSat as part of the QB50 project on 5th of July, 2017.
This was followed with a successful M6P mission in 2019 as well as multiple component- to system-level qualification campaigns resulting in a flight-qualified and flight-ready system with already existent flight heritage.
Additionally, two EPSS C2 propulsion systems and one EPSS C3 system have been recently flight-accepted for the missions to be launched in approximately 2 years.
Testing & qualification
Standard EPSS configurations are qualified (environmentally and functionally tested) according to ECSS standards to be immediately ready for mission integration.
