High-thrust green chemical satellite thruster with closed-loop pressure control from GATE Space.
The GATE Thruster is sold in three sizes — Thruster S (2-20 N), Thruster M (5-50 N) and Thruster L (20-200 N) — with listed base prices of EUR 30,000, EUR 40,000 and EUR 50,000 respectively. All variants fit envelopes of up to roughly 1-2 kg mass and 75-100 mm diameter.
Each thruster runs on storable green propellants (ethane and nitrous oxide) at 270-300 s specific impulse, supporting continuous, pulsed (up to 10 Hz) and cold-gas operation across a 1:10 throttling range. Patented injection technology and closed-loop combustion-chamber pressure control keep thrust output predictable during sensitive maneuvers.
