This is a hardened version of the heritage 1 Nms wheel, suitable for high orbits. It uses rad-hard parts, has a shielded enclosure, and employs an active mechanism to mitigate deep charging of the rotor assembly. Power consumption is greatly reduced.
First flight deliveries are scheduled for December 2019.
