Compact, Rugged Tactical Grade MEMS Inertial Measurement Unit
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.
The SDI170 IMU is designed for demanding, mission-critical, rugged environments and ideal for continuous use applications with no wear-out components, highly linear accelerometer performance and longer life compared to competing alternatives. It is constructed with EMCORE’s latest generation quartz gyros, quartz accelerometers, and high-speed signal processing to achieve outstanding precision performance. The solid-state quartz sensors and hermetically sealed IMU construction provide reliable MTBF and a 20-year operating and storage life. Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection and flexible input power compatibility make the SDI170 IMU easy to use in a wide range of higher-order integrated commercial and defense system applications.
