WaterCube: a water-based propulsion system for Cubesats and Smallsats. Its main benefits are:

• Non-pressurised: reducing ground testing and safety requirements for rideshare payloads
• Sustainable and green: demineralised water as propellant
• Customizable: propellant loading up to 1 kg of water, depending on user needs. Tank shape customized according to user's form factor needs
• Low power consumption: several operational modes with power consumption 5 - 25 W (depending on operational mode)
• Miniaturised: unit volume starting from 0.6U, up to 1.5U, depending on propellant amount loaded
• High performance:
  • Specific Impulse > 90 s
  • Thrust 3 - 4 mN
  • Total Impulse 200 - 1000 Ns (depending on propellant amount)
  • Suitable for any orbital maneuver:
    • Collision avoidance
    • Orbit maintenance
    • Formation flight / rephasing
    • De-orbiting
    • Attitude control / proximity operations (for Smallsats)
• Short lead time: 3-months delivery from order signature
• Modular: can be clustered in several units thanks to its plug-and-play capability to meet user needs
• Affordable: the system is designed to be produced quickly and cheaply to meet low-budget cubesat and smallsat mission needs
