Unrelated to EmDrive, but similar... is the thruster based on the theory of Quantized Inertia[0]... it passed multiple lab tests on the ground, and is now in orbit[1,2], waiting for the other experiments in the satellite to be completed before they power it up. If it works as expected, they'll be boosting the orbit of the satellite by 100km without using propellant, thanks to a 1 milliNewton electric thruster pushing on its mass of 4.8 Kg.
