Open-Loop FOG, IMU & INS
EMCORE’s portfolio of Fiber Optic Gyros (FOG), IMUs and INS with has expanded to include the open-loop FOG-based products with
Photonic Integrated Chip (PIC) acquired in 2022 from KVH Industries. Proven aboard autonomous platforms worldwide, they bridge
the gaps in satellite navigation with precision data, very high bandwidth, low latency, and low drift.
TAC-450 Series Tactical Grade Fiber Optic Gyros (FOG) & IMUs TAC-450 FOG
EMCORE’s TAC-450 series products are designed to deliver the highest level of performance in
their class and feature our exclusive Photonic Integrated Chip (PIC) technology. Models include
the TAC-450 FOG, TAC-450-360 IMU, TAC-450-340 IMU and TAC-450-320 IMU which enable
customers to select the performance level that best fits the requirements of their application.
TAC-450 FOG
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.
TAC-450-360 IMU
The TAC-450-360 IMU is one of the premier IMUs offered by EMCORE and is designed to deliver
the highest level of performance for applications in which high bandwidth, low latency, and low
drift are critical. The TAC-450-360 IMU with inertial-grade accelerometers and three axes of mag-
netometers provides the high accuracy that leading autonomous and manned platforms demand. TAC-450 IMU
