TAC-450 Fiber Optic Gyro (FOG) (Non-ITAR)

Compact Single- or Multi-axis Fiber Optic Gyros Designed for Maximum Ease of Integration

EMCORE’s TAC-450 Fiber Optic Gyros (FOGs) combine single- or multi-axes of the world’s smallest high performance FOGs within easy-to-integrate housings, or unhoused for OEM configurations. The TAC-450 FOG offers exceptional performance in bias stability, scale factor, and angle random walk, and is available in nine configurations to solve the most challenging design projects. The TAC-450 FOG is ideal for air, land, or maritime stabilization and pointing applications. Due to its versatility, and accurate, reliable output, it can also be utilized in navigation, guidance, and control systems.


  • Designed for maximum ease of integration with housed or unhoused (for OEM configurations) options
  • Available in nine configurations to solve the most challenging design projects
  • Exceptional performance in bias stability, scale factor, and angle random walk
  • 1-, 2-, or 3-axis configuration, each employing the world’s smallest precision FOG

Technology Details

Photonic Integrated Chip Technology
EMCORE’s photonic integrated chip (PIC) technology* reimagines FOG technology by replacing individual fiber components with an innovative integrated planar optic chip. This results in a FOG with PIC Inside™ that’s reliable and robust. With three of these integrated photonic gyros at its core, the TAC-450-360 IMU provides the safe, accurate performance autonomous platforms demand.
