GATE Thruster

Highest precision with
unmatched performance

Highest precision

With closed-loop pressure control via the combustion chamber, the GATE Thruster delivers consistently accurate performance. This ensures precise and reliable thrust output even in complex environments or during sensitive maneuvers.

Patented deep throttling

With its patented injection technology, the GATE Thruster provides stable and predictable deep throttling over a 1:10 range. It supports steady-state operation, transient thrust profiles, and precise pulsed firings at up to 10 Hz—enabling smooth handling across all mission phases.

Superior performance

Combining responsiveness and high thrust performance with careful system engineering, the GATE Thruster enables agile yet controlled maneuvers. It supports both high-performance spacecraft and tactically responsive missions.

Proven reliability ✓

Proven in over 2,000 successful hot-fire tests in atmospheric and vacuum conditions, the GATE Thruster is extensively tested and ready for your space mission.

High-performance,
green propellants

Simple architecture

Our self-pressurizing propellant combination of nitrous oxide (N2O) and ethane (C2H6) eliminates the need for complex pressurant components and single points of failure. This simplified architecture translates directly into higher system reliability and ease of integration.

High performance

Delivering a specific impulse (ISP) of up to 300s – comparable to legacy hydrazine systems – our propellant combination enables high-thrust, high-efficiency maneuvers for even the most demanding space missions.

Long-term storability

Our propellants remain stable for years—both on the ground and in orbit—making them ideal for extended missions, long-duration storage, and responsive launch scenarios.
