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

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).

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.
