The ARM-A from Aurora Propulsion Technologies is a Spacecraft Thruster that is designed for small satellites with a mission life of 3+ years. It has a form factor of 0.35/5/1 U and a thrust value of 0.6-4 mN. This water-resistojet thruster utilizes a water-based propellant and has a specific impulse of 100 s. It has an active power consumption of 3 - 5 W and an idle power consumption of 50 mW. The thruster has a mass of 1 kg/U and supports CAN, I2C, and RS-485 command interfaces. It is a full 3-axis attitude control system with 6 resistojet thrusters. The ARM-A thruster is ideal for use in CubeSats (1-3 U), nano- and microsatellites.
