MEMS IMU

EMCORE’s MEMS IMUs and Navigation Systems (GPS/INS), based on our Systron Donner Quartz
INERTIAL MEASUREMENT UNITS & NAVIGATION SYSTEMS
MEMS technology, deliver unprecedented performance in their class. They are designed for a
wide variety of high-precision Commercial, Industrial, Marine, and Defense Applications.
QUARTZ MEMS
QUARTZ MEMS
SDI500 Tactical Grade IMU
The SDI500 IMU outperforms other MEMS IMUs and delivers comparable performance to older,
costlier optical IMUs in a lower power, smaller, and lighter form factor. With 1°/hr gyro bias, 1 mg
accelerometer bias stability and very low 0.02°/√hr Angle Random Walk (ARW) over wide tem-
perature ranges, the SDI500 is designed to achieve the demanding performance levels required in
sophisticated systems applications and is well-suited for use by Integrators and OEMs.

Features/Benefits Applications
n Excellent Bias Stability n Missile & Torpedo Guidance,
Control & Targeting
n Unprecedented Low Angle Random Walk Values
n Precision Guided Munitions
n Superior Vibration Performance n Defense Fixed Wing and Helicopter
n Miniature, Small Footprint Size (19 cubic inches) n UAVs and UUVs
n Solid-State, One-Piece Sensor Design, High MTBF n Tank Turret Stabilization
n Multiple Data Formats/Output Interfaces n Platform Stabilization

SDI170 Tactical Grade IMU

EMCORE’s SDI170 IMU is designed as a performance-compatible inertial system that is form, fit, and
functional with a legacy RLG-based IMU product, but with superior overall performance, versatility,
and a significantly higher MTBF (Mean Time Before Failure) rating over ruggedized environments.
The tactical performance of the SDI170 IMU is based on EMCORE’s mature, proven, dependable,
and accurate quartz MEMS inertial sensor technology in our SDI500 tactical-grade IMU.
Features/Benefits Applications
