IMU-Kernel-110,120
Breakthrough, Fully Integrated MEMS IMU
The Inertial Labs KERNEL-110 and KERNEL-120 models are the breakthrough, fully integrated inertial solutions that combine the latest MEMS sensor technologies. KERNEL-120 model utilizes two types of accelerometers: with ±40g and ±90g measurement ranges.
Description
The Inertial Labs MEMS KERNEL Inertial Measurement Units (IMUs) & Digital Tilt Sensors are the second generation of the Inertial Labs KERNEL Miniature MEMS sensor-based family. Revolutionary due to being very compact and self-contained strap-down, the industrial-grade IMUs measure linear accelerations and angular rates with three-axis MEMS accelerometers and three-axis MEMS gyroscopes. Angular rates and accelerations are determined with low noise and very good repeatability for both motionless and dynamic applications.
Fully calibrated, temperature compensated, and mathematically aligned to an orthogonal coordinate system, the IMU contains up to 2 deg/hr Bias in-run stability gyroscopes and 0.01 mg Bias in-run stability accelerometers with very low noise and high reliability. Continuous Built-in Test (BIT), configurable communications protocols and flexible input power requirements make the Inertial Labs KERNEL easy to use in a wide range of higher-order integrated system applications.
The Inertial Labs KERNEL models were designed for applications, like:
- Autonomous vehicles
- Antenna and Line of Sight Stabilization Systems
- Passenger train's acceleration/deceleration and jerking systems
- Motion Reference Units (MRU) and Motion Control Sensors (MCS)
- Gimbals, EOC/IR, platforms orientation and stabilization
- GPS-Aided Inertial Navigation Systems (INS)
- Attitude and Heading Reference Systems (AHRS)
- UAV & AUV/ROV navigation and control
