Navigation Systems
ALR-IMU SERIES
Precision inertial sensing for navigation, stabilization and motion control.
Three performance grades. Configurable measurement ranges. One compact form factor.
Engineered for reliable motion sensing in demanding environments, the ALUNOR IMU Series delivers precise three-axis angular-rate and acceleration measurements through advanced MEMS sensors, low-noise signal processing and comprehensive temperature calibration. Available in three performance configurations; ALR-IMU-011, ALR-IMU-012 and ALR-IMU-013. The series supports land vehicles, UAVs, aircraft, maritime platforms, autonomous systems and high-dynamic applications.
