About
Comat’s SADM systems are designed to provide continuous power generation in orbit by ensuring precise and continuous solar array orientation toward the Sun. This maximizes spacecraft power generation throughout the mission. Built around a high-integrity slip ring system, these mechanisms enable unlimited rotation while reliably transferring power and signals. The SADM-CP (Compact Power) variant offers up to 400 W per wing power transfer, a maximum torque of 0.35 Nm, and an operational lifetime of a minimum of 5 years in LEO. The SADM-HP (High Power) variant provides up to 4000 W per wing power transfer, a maximum torque of 0.35 Nm, and an operational lifetime of a minimum of 10 years in LEO. These mechanisms are built with a focus on a compact yet robust design, minimizing mechanical footprint while maximizing the reliability of energy harvesting. They feature unlimited rotation for optimal solar tracking, advanced connectivity through integrated high-reliability slip ring technology, and a space-saving compact architecture for easy integration. Comat produces its SADMs with the same serial manufacturing precision as its reaction wheels, scaling production to meet the evolving demands of constellations with higher power requirements and longer durations.
