Tactical-Grade MEMS IMU Launched

Published: 13 Apr 2021 by

Inertial Labs IMU-NAV-100Inertial Labs has launched the IMU-NAV-100, a new tactical-grade MEMS IMU (inertial measurement unit) that is now the best-performing in Inertial Labs’ portfolio. The new sensor is a fully integrated inertial solution that measures linear accelerations, angular rates, and pitch/roll with high accuracy, utilizing state-of-the-art three-axis MEMS accelerometers and gyroscopes.

The IMU-NAV-100 is available in two variants to suit a wide variety of system requirements. The IMU-NAV-100-S is ideal for high-performance antenna and line-of-sight stabilization systems, motion control sensors (MCS), and platform orientation and stabilization systems. With a gyroscope angular random walk of only 0.04 deg/√hr, the IMU-NAV-100-S is specially designed to provide accurate data for stabilization applications. The second model is the IMU-NAV-100-A, which is ideal for integrated systems such as GPS-Aided Inertial Navigation Systems (INS), Attitude and Heading Reference Systems (AHRS), and Motion Reference Units (MRU). Both models provide pitch & roll accuracy of 0.03 deg RMS.

The IMU-NAV-100 also features Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection, and flexible input power requirements for easy integration into higher order systems. Fully calibrated, temperature compensated, and mathematically aligned to an orthogonal coordinate system, the IMU contains up to 0.5 deg/hr bias in-run stability gyroscopes and 0.003 mg bias in-run stability accelerometers with very low noise and high reliability.
