Overview

Versatile, Highly Accurate Photonic FOG-based IMU for Demanding Fully Autonomous and Manned Applications

The new EMCORE TAC-450-340 IMU delivers exceptional performance thanks to EMCORE’s exclusive photonic integrated chip (PIC) technology and high-performance inertial-grade MEMS accelerometers. 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 versatile TAC-450 340-IMU offers flexibility with its wide range of high-end inertial-grade accelerometers, selectable baud rates, and input power levels. The non-ITAR TAC-450-340 IMU is fully-configurable by the end-user and provides outstanding performance for demanding applications such as autonomous platforms operating in the air, on land, and at sea.

The TAC-450-340 IMU offers excellent shock and vibration tolerance over competing technologies. Tactical-grade photonic FOGs are integrated with three low noise, inertial-grade MEMS accelerometers. The high-performance TAC-450-340 IMU is designed for systems and applications where low Angle Random Walk (ARW), bias instability, high scale factor accuracy, very high bandwidth, and low latency are critical parameters for success.

PIC Technology for Superior Performance

EMCORE’s exclusive PIC technology uses an integrated planar optic chip, resulting in a sensor that delivers robust performance and survivability in challenging environments. With three integrated photonic gyros at its core, the TAC-450-340 IMU provides the essential precision navigational support that autonomous navigation and other applications demand.

Improved SWaP for Ease of Integration

The high-performance EMCORE TAC-450-340 offers great SWaP in a sturdy, compact package. Designed for drop-in replacement for many available IMUs, the TAC-450-340 IMU’s flexible interface and programmable digital data simplify the integration of the TAC-450 system. This inertial sensor offers ease of integration for designers of higher-level inertial navigation, guidance, and stabilization systems by providing user-selectable features, including an adjustable baud rate to adjust communication latency to receive accurate, timely data. To maximize versatility, the TAC-450-340 IMU enables programmable message outputs from both the TAC-450-340 IMU’s photonic FOGs and integrated high-grade accelerometers.

The TAC-450-340 IMU is ideal for autonomous platform navigation, precision pointing and stabilization, GNSS-aiding, mapping and surveying, guidance, positioning, and motion sensing.
