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. 

EMCORE’s quartz technology enables repeatable high-volume production of precisely machined sensor structures combined with the inherent large signal output and thermal stability of quartz materials.
