Emcore is offering two inertial measurement units (IMUs) suitable for the defense market.

SDI500 Tactical Grade IMU. Emcore’s Systron Donner Inertial SDI500 is a high-performance MEMS-based IMU that demonstrates true tactical grade performance with 1°/hour gyro bias and 1-mg accelerometer bias stability with very low 0.02°/hr angle random walk. Its performance is based on Emcore’s quartz MEMS inertial sensor technology. The SDI500 is designed to achieve the demanding performance levels required in sophisticated systems applications. Packaged in a highly miniaturized, cylindrical configuration with a volume of 19 cubic inches, it is suitable for use by integrators and OEMs.

The SDI500 is a compact IMU constructed with SDI’s next generation quartz gyros, quartz accelerometers, and high-speed signal processing that achieves tactical grade performance. The SDI500 IMU is rated for rugged military environments.

EN-300 Precision Fiber Optic IMU/INS. The EN-300 inertial system is designed to be compatible in form, fit and function with a legacy equivalent, but with the higher accuracy and performance needed for GPS-denied navigation, precise targeting and line-of-sight stabilization.

It features navigational-grade performance with 0.04°/hr gyro bias and 0.1-mg accelerometer bias stability with ultra-low 0.007°/hr angle random walk.

Internal signal processing provides full stand-alone or aided navigation, and as an option can provide standard IMU delta velocity and delta theta.
