GO-2 Electric Propulsion System
Modular ~1U FEEP electric propulsion unit with 40 individually controlled thrusters and solid metallic propellant, for spacecraft from 6U upwards.
Description
From constellation deployment and repositioning to deorbiting, collision avoidance, and station keeping, the GO-2 electric satellite propulsion system is equipped to handle every aspect of the mission. It is built to be the simplest, most efficient and cost-effective propulsion system, enabling mobility throughout the entire mission lifetime.
Efficient: the total impulse provided by the GO-2 system enables satellite mobility for long durations, ensuring satellite operators get full value out of their payload.
Reliable: each GO-2 system contains 40 individual thrusters, each with its own propellant tank and independent thrust control, offering an unprecedented level of redundancy and precision.
Modular: as a modular propulsion unit at approximately 1U in size, GO-2 can support a wide range of spacecraft from 6U and up.
Key features include a plug and play design that removes complexities of system integration; a solid metallic propellant that ensures zero leakage, with no moving parts, chemicals or pressurization; engineered high redundancy to maximize operational uptime and reliability; and 40 individually controlled thrusters enabling precise maneuvering for various mission requirements. GO-2 builds on three generations of space-proven technology, with core technology in orbit since 2018, support of commercial customer missions in space since 2023, the first-ever in-space test of a nanosatellite propulsion system and the world's first nanosatellite collision avoidance maneuver.
