JSOW Missile Seeker Head

Allied Motion engineers designed a high resolution motor-encoder, limited-angle actuator to meet the extremely demanding requirements of modern smart standoff weapons such as the JSOW missile shown here.

The Allied Motion custom actuator positions an infrared imaging seeker, a critical part of the weapon’s precision autonomous guidance system. The actuator includes an 18-bit absolute encoder and limited-angle brushless torque motor. The encoder has a high bandwidth 2000 Hz (word rate) serial interface for high resolution and high speed positioning.
