About
The Plan-S Magnetic Torque Rod family offers compact, power-efficient, and integration-friendly magnetic actuation solutions for spacecraft attitude control systems. These devices are designed to simplify ADCS integration and support reliable in-orbit attitude control. By combining magnetic actuation with integrated drive electronics and mission-focused interface options, the family helps reduce external hardware requirements, simplify spacecraft-level integration, and support more predictable ADCS performance. Engineered to address different platform needs within the small satellite and microsatellite segment, the product family supports critical in-orbit operations such as early-phase stabilization and momentum management throughout the mission lifecycle. Its low residual magnetization, efficient power profile, and digital control approach enable satellite teams to achieve reliable magnetic control while keeping system complexity, harnessing effort, and integration risk under control. The product family offers solutions for different spacecraft platform needs, from compact 6U-class small satellites to microsatellite missions requiring higher magnetic authority.
