EN-300 Precision Fiber Optic Inertial Measurement Unit (IMU) (Non-ITAR)

EMCORE has developed the EN-300 Precision Fiber Optic Inertial Measurement Unit as a higher accuracy inertial system to be form, fit and function compatible with a legacy product, but with better performance needed for GPS denied navigation, precise targeting and line-of-sight stabilization. The EMCORE EN-300 is a state-of-the-art design incorporating EMCORE’s proprietary integrated optics devices to enhance performance, providing up to five-times better performance than competing systems. The internal signal processing provides full stand-alone navigation, and as an option can provide standard inertial measurement unit (IMU) delta velocity and delta theta.

The EMCORE EN-300 provides lower noise and greater stability than competing IMUs and is able to statically find North to less than one degree through gyro-compassing. The EN-300’s digital interface is fully programmable within EMCORE’s factory allowing it to directly replace lower performing competing units. It has the same style connector, pinouts and signals as a commonly used FOG IMU from a leading competitor.
