Inertial Labs KERNEL-100 – Inertial Measurement Unit & Digital Tilt Sensor

High Precision Inertial Measurement Unit and Digital Tilt Sensor (Pitch & Roll)

The Inertial Labs MEMS KERNEL Inertial Measurement Units & Digital Tilt Sensors are the latest addition to the Inertial Labs Advanced Miniature MEMS sensor-based family. Revolutionary due to its very compact, self-contained strapdown, industrial-grade Inertial Measurement Systems that measures linear accelerations and angular rates with three-axis MEMS accelerometers and three-axis MEMS gyroscopes.

Description


The Inertial Labs KERNEL-100 is the breakthrough, fully integrated inertial solution that combines the latest MEMS sensor technologies. Fully calibrated, temperature compensated, mathematically aligned to an orthogonal coordinate system, the IMU contains up to 1.5 deg/hr Bias in-run stability gyroscopes and 5 ug Bias in-run stability 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 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
  • Passengers trains 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)
  • Land vehicles navigation and motion analysis
  • Buoy or Racing Boat Motion Monitoring
  • UAV & AUV/ROV navigation and control
