The D3 modulates spacecraft drag force, while controlling orientation and orbital decay. It can be used to control a satellite constellation, deorbit a satellite, and target the re-entry location. It does all of this passively, without any rocket propellant. The D3 is a simple, reliable, low-cost, non-propulsive system. Any operators of a small spacecraft can use the D3. This includes CubeSats, CYGNSS spacecraft, ESPA Class spacecraft, and the Orion 38 motor (depleted).
