Guided Munition

Our magnets are engineered for:

  • Control Actuation: Magnetic couplings are used in control actuation systems to transmit torque without mechanical contact, improving reliability and ensuring precise fin and control surface movement under extreme vibration and thermal stress.
  • Guidance: High-accuracy magnetic sensor assemblies provide critical position and speed feedback for guidance systems, supporting real-time course correction and consistent accuracy throughout the mission.
  • Propulsion: High-performance motor magnet assemblies power propulsion and thrust-vector control systems, delivering efficient, stable operation across wide temperature ranges and demanding duty cycles.
  • Radar: Custom-engineered magnetic assemblies support radar and seeker subsystems by maintaining electromagnetic stability, signal integrity, and dependable operation in harsh, electronically dense environments.

Unmanned Aerial Systems

We engineer systems for:

  • Flight Control: Precision magnetic assemblies enable accurate, responsive flight control by supporting actuators and motors that manage control surfaces, gimbals, and stabilization systems under continuous vibration and dynamic loading.
  • Radar: Custom magnetic assemblies are used in radar and sensing platforms to ensure electromagnetic stability, precise motion control, and reliable performance in compact, weight-constrained UAS architectures.
  • Navigations: Magnetic sensors and assemblies support navigation subsystems by delivering reliable heading, position, and motion feedback, ensuring accurate localization and stable operation in GPS-denied or contested environments..
