2020-131 – Energy efficient intelligent structure for attitude control of satellite

  • Improved satellite/spacecraft attitude control that rotates a body to an arbitrarily large degree in space


James Allison and researchers from the University of Illinois have developed a technology that provides fine pointing and large slew attitude control for satellites and spacecraft with a power electronics driver circuit that improves the power efficiency of the system by at least one order of magnitude. The invention features a dedicated compliant actuator on a vehicle to produce the torques to achieve arbitrarily large rotations around all axis without the jitter limitation of other attitude control system.

Potential Applications

Primary application: accurate and precise attitude control for satellites/spacecraft
