Description
Overview
Affordable, Robust Photonic FOG-based IMU with High-performance in Challenging Stabilization and Navigation Applications
The new EMCORE TAC-320 IMU is a dependable, tactical-grade, non-ITAR inertial system that’s also affordable. The TAC-450-320 features EMCORE’s exclusive photonic integrated chip (PIC) technology to deliver robust performance and survivability in the harshest environments. EMCORE’s PIC technology provides more efficient fiber optic gyroscopes (FOGs) over traditional open-loop FOG technology by replacing previously high-touch optical components with a single precision-manufactured silicon chip.
The TAC-450 320-IMU meets the demanding needs of a broad range of navigation and stabilization applications and is offered with a 16g inertial-grade high-performance accelerometer. With excellent FOG performance as affordable as MEMS
alternatives, the TAC-450-320 IMU delivers outstanding performance and low cost. With three state-of-the-art photonic FOGs integrated with three high-grade low noise inertial accelerometers, the TAC-450-320 IMU is ideal for manned and unmanned platforms and navigation and stabilization systems in which affordability, high performance, and high bandwidth are critical for success.
PIC Technology for Dependable Performance
EMCORE’s exclusive PIC technology reinvents traditional FOG technology using an integrated planar optical chip, resulting in a sensor that delivers exceptional performance and survivability in challenging environments. The TAC-450-320 IMU offers a user-configurable baud rate to adjust communication latency and user-selectable message outputs from both the TAC-450 photonic FOGs and integrated high-grade accelerometers.
