iG20 thruster
A 20-newton thruster that burns non-toxic nitrous oxide and ethane. InterGravity uses it on its own tugs and also lists it as a standalone product.
Why it matters
A non-toxic propellant pair can make small spacecraft propulsion simpler and safer to handle on the ground. InterGravity builds the thruster in house and offers it alongside its tugs.
How the technology works
The iG20 burns nitrous oxide and ethane together as a bipropellant and produces 20 newtons of thrust, the same thrust rating as the engine on InterGravity's iGRVT-50 tug. InterGravity also makes lightweight Type III composite pressure tanks (iCOPV).
