Overview
The IMU-FI-200C Inertial Labs Inertial Measurement Unit is the latest addition to the Inertial Labs Advanced Inertial Measurement Units (IMU) family. Revolutionary due to its compact, self-contained strapdown, advanced tactical-grade Inertial Measurement Units, that measures linear accelerations and angular rates with three-axis tactical-grade, closed loop Fiber-Optic Gyroscopes (FOG) and three-axis high-precision MEMS accelerometers in motionless and high dynamic applications.
Officially classified as ECCN 7A994 (NLR – No License Required), IMU-FI-200C is a breakthrough, fully integrated inertial measurement solution that combines the latest closed-loop FOG and MEMS sensors technologies.
Fully calibrated, temperature compensated, mathematically aligned to an orthogonal coordinate system, the IMU contains up to 0.5 deg/hr gyroscopes and less than 2 mg bias repeatability over operational range accelerometers with very low noise and high reliability.
Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection, and flexible input power requirements make the Inertial Labs IMU-FI-200C easy to use in a wide range of higher order integrated system applications.
