The Palomar Micro Propulsion System is primarily a reaction control system with thrusters arranged so that use of all six degrees of freedom (DoF) in rotation and translation are possible.
Additional propellant is available by stretching the tank lobes, allowing for a custom propulsion module mass and volume based on specific mission needs.
Upgrades to other propellants available.
- Over 200,000 thruster firings in a simulated space environment
- Ten frictionless valves for thrust, plenum pressure regulation, and filling
- Eight independent thrusters
- Simple command protocol for operation and health monitoring
- Liquid isobutane propellant provides high storage density; other propellants available
- Complete propulsion system in one monolithic
- 5V power supply and I2C serial data interface
