Fiber Optic Gyroscopes, FOG IMUs and FOG-INS for Land, Sea, Air & Space Navigation

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 >

EN-150 Inertial Measurement/Navigation Unit

High accuracy FOG-based IMU for UAVs, Dismounted Soldiers and Platform Stabilization

The EN-150 Precision Fiber Optic Inertial Measurement/Navigation Unit is our smallest Fiber Optic Gyro-based Inertial Measurement Unit (IMU) and the smallest closed-loop FOG IMU available today. This high-accuracy unit is designed to operate as both an inertial measurement unit or navigator with up to two-times the performance of competing IMUs.

It is ideal for use as an inertial navigation system for UAVs, dismounted soldier, gun stabilization/targeting applications as well as navigation in GPS-denied environments. The EN-150 is a higher accuracy inertial system that is one-third the volume and weight of a legacy RLG-based IMU product with better performance.

The system incorporates three precision FOGs and three precision MEMS accelerometers, as well as integrated optics and next-generation FPGA electronics for high-efficiency calibration and system modeling. With the option of full navigation capability, the EN-150 includes options for coning and sculling compensation, sophisticated Kalman filtering and external aiding e.g. via GPS.

The EN-150 is available in three performance variants:

EN-300 Inertial Measurement/Navigation 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:

EMCORE-Orion™ Series Micro Inertial Navigation System (MINAV)

High-Precision Micro INS for GPS-Denied UAVs

The EMCORE-Orion™ series of high-precision Micro Inertial Navigation Systems (MINAV) is designed for unmanned vehicle navigation in GPS-denied environments, as well as accurate inertial measurement. The state-of-the-art technology provides navigation-grade performance close to that of a traditional RLG INS with 1/3 of the Size, Weight and Power (SWaP) requirements.

The low-noise, high-stability system incorporates our proprietary integrated electronics and optics devices, including a precision three-axis closed loop FOG, mechanical accelerometers and state-of-the-art FPGA electronics. The unit is able to be aided by an external GPS. In a GPS-denied environment the EN-1000 MINAV series will gyrocompass from approximately 0.8 to 1.2 milliradians depending on the model.
