High Performance FOG and Quartz MEMS Inertial Sensors - Gyros, IMU, INS

EMCORE Corporation Visit Website

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

EMCORE EG-120 Compact FOG for UAVsThe 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

EMCORE EG-200 Tactical Solid-State FOGThe 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 applicationsEMCORE EG-1300 Navigational Grade FOG

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.
