The ADCS-R3 sub-system uses the momentum wheels to provide precise, stable, durable 3-axis attitude control.
The four integrated reaction wheels are arranged in a tetrahedron configuration, enabling full system control without having to reverse the spin direction. In the event of a single wheel failure, the three additional wheels can be reconfigured for exercising full control with only slightly degraded performance.
The magnetorquer rods are wound on ultra-high permeability material in order to provide high efficiency.
