The 5CGT0003 is a compact, high-efficiency cold gas thruster including a monostable, normally closed fast solenoid valve and delivering a minimum impulse bit of 20 mN·s, with valve response times of 3 ms on both opening and closing commands. This level of responsiveness enables precise spacecraft attitude control across a broad range of mission-critical applications, including rendezvous and docking operations, reaction wheel momentum unloading, and launch vehicle upper stage attitude control.
