The MEMS PicoSat Inspector (MEPSI) Micro-Propulsion System (MiPS) is a cold gas propulsion module designed for 1U CubeSats.
Using Chemically Etched Micro System (ChEMS™) technology, VACCO has produced a complete CubeSat propulsion system including propellant storage, pressurization, distribution and thrusters. This simple, highly integrated design uses a self-pressurizing liquid propellant that is expelled as a gas.
Capable of 23 N-Sec of total impulse with up to 43,000 firings, MiPS brings true propulsion capabilities to micro-spacecraft for formation flying, attitude control and velocity change (delta-v).
- Five thrusters for pitch, yaw, roll and delta-v
- 53 mN thrust
- Up to 43,000 minimum impulse firings
- Redundant, frictionless valves
- All-welded titanium construction
- Dry mass: 456 grams
- Integral pressure & temperature sensors
