Field emission electric propulsion offers significantly higher efficiency than chemical propulsion, allowing satellites to achieve greater maneuvering capability with less propellant. This enables longer operational lifetimes, increased payload capacity, and greater flexibility for in-orbit mobility.GO-2’s solid metallic propellant eliminates the need for moving parts and pressurization, while also eliminating the risk of chemical leakage.For dynamic satellite missions, electric propulsion is a key enabler of cost-effective and sustainable space operations.
​
One of the biggest advantages of GO-2 over other electric propulsion systems is its resiliency. GO-2 contains 40 independent thrusters, each with its own dedicated power supply, improving fault tolerance and operational robustness.While many FEEP systems use Indium as a propellant with a relatively high melting point of 156.6 °C, GO-2 employs a proprietary metallic alloy that remains solid during storage, shipping, and launch but liquefies at much lower temperatures. This allows GO-2 to reach operational readiness much faster, requiring only 30–45 minutes from a cold start with less power.GO-2 is also simple to operate, requiring just three basic commands to transition from startup to firing, delivering reliable performance, improved thermal management, and fast system response.
​
Propulsion systems are mission-critical for satellite mobility and safety. GO-2’s redundant architecture improves fault tolerance and reduces the risk of mobility loss on orbit, supporting long-duration commercial and government missions that demand high operational resilience.

GO-2’s FEEP-based propulsion enables fine control through individual thruster operation and thrust vectoring. This allows accurate and repeatable trajectory adjustments and supports advanced mission requirements, including rendezvous and proximity operations (RPO). High total impulse enables sustained RPO maneuvering with minimal propellant consumption, preserving delta-v for repeated proximity operations and extended mission duration.

Power availability and mass allocation are key design drivers for satellite propulsion systems. GO-2 operates efficiently at relatively low power levels. A 7-40 W power draw enables flexible duty cycles and continuous low-thrust operation without disrupting spacecraft power budgets or payload activities.
Its compact, integrated design minimizes mass and volume, helping operators maximize payload capacity while maintaining mobility capability.

GO-2 is self-contained and connects to the satellite through a single interface for both power and communication. By using a proprietary solid metallic propellant and eliminating complex valves and pressurized tanks, GO-2 reduces integration complexity, testing effort, and scheduling risk for satellite programs.
