Fiber Optic Gyro (FOG) IMU

EMCORE’s Inertial Measurement Units (IMUs) and Inertial Navigation Systems (INS), based on our advanced FOG technology, provide
INERTIAL MEASUREMENT UNITS & NAVIGATION SYSTEMS
higher performance and superior CSWaP compared to competing systems. They provide customers the flexibility to choose options
for full navigation, straightforward IMU operation, or higher performance form, fit and function replacements for legacy systems.
EN-300 Inertial Measurement/Navigation Unit (Non-ITAR)
EMCORE’s EN-300 Precision Fiber Optic Inertial Measurement/Navigation Unit is a higher ac-
curacy inertial system that is 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. This state-of-the-art design incorporates EMCORE’s proprietary integrated optics
to enhance accuracy, providing up to ten-times better performance than competing systems.
