EMCORE is a leading provider of high-performance inertial navigation sensors and systems for aerospace, defense and commercial markets.

Our product suite utilizes Emcore’s state-of-the-art closed-loop Fiber Optic Gyroscope (FOG) sensor technology, along with recently acquired Systron Donner Inertial’s quartz MEMS inertial sensing solutions, to meet the demanding requirements of SWaP-conscious unmanned applications.

Our tactical and navigation grade gyroscopes, IMUs, and Inertial Navigation Systems (INS) are ideal for navigation, control and stabilization of UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles) and AUVs/UUVs (unmanned underwater vehicles).

Fiber Optic Gyroscope (FOG) Sensors

EMCORE-Hawkeye™ EG-120 FOG

Ultra-compact, closed-loop gyroscope for demanding applications

The EG-120 FOG module is our smallest closed-loop FOG and the smallest, most affordable closed-loop FOG available on the market today. It features industry-leading SWaP characteristics and incorporates next-generation Field Programmable Gate Array (FPGA) electronics that deliver increased performance and reliability.

The EG-120 is an ideal solution for medium accuracy platform stabilization applications such as UAV weapons and camera systems. It is also available in a low power variant. Jump to specifications >

EMCORE-Hawkeye™ EG-200 FOG

Precision solid-state gyroscope for tactical grade applications

The EG-200 is a tactical-grade FOG designed for high-accuracy navigation and low-noise line-of-sight stabilization applications. It features fully-integrated optics and Field Programmable Gate Array (FPGA) electronics, resulting in improved optical drift stability, higher linearity and greater environmental flexibility.

EG-200 units can be calibrated internally for better thermal effect, and have both digital and analog outputs, accommodating a wide variety of installation and interfacing parameters. Jump to specifications >

EMCORE-Hawkeye™ EG-1300 FOG

Low-noise gyroscope for navigational grade applications

The EG-1300 is our lowest-noise FOG, ideal for precision navigation in GPS-denied environments – such as UUVs – as well as platform stabilization. Featuring advanced integrated optics and closed-loop FPGA design, it delivers higher accuracy, lower noise and greater efficiency in a low-SWaP package.

The EG-1300 can be calibrated internally for better thermal effect. In addition to providing both digital and analog outputs, the unit features separation of the electronics from the FOG’s sensing coil assembly, allowing for the most flexible installation and integration capabilities.

Inertial Measurement Units (IMU)

EN-300 Precision Fiber Optic Inertial Measurement Unit

Precision Three-Axis FOG IMU for UAVs

The EN-300 is a higher-accuracy Fiber Optic Gyro-based IMU that is a form, fit and function compatible with a legacy equivalent, but with better performance needed for GPS denied navigation, precise targeting and line-of-sight stabilization. Applications include in inertial navigation for UAVs, dismounted soldiers, civilian unmanned aviation, and oil and gas exploration.

The low-noise, high-stability unit provides up to five-times better performance that competing system. It features internal signal processing that provides full stand-alone or aided navigation, with optional standard IMU delta velocity and delta theta outputs. With state-of-the-art FPGA electronics and sophisticated Kalman filtering, the unit is able to statically find North to less than one degree through gyro-compassing.

The EN-300 is available in three performance variants:
