Inertial Labs has released an article that provides detailed insights into the company’s Kernel-100 Inertial Measurement Unit (IMU) and Digital Tilt Sensor (DTS). The lightweight, compact system incorporates precision tri-axis MEMS accelerometers and tri-axis MEMS gyroscopes, and measures linear accelerations and angular rates with low noise and good repeatability.
The article covers:
- The temperature calibration process for the Kernel-100, with details of how data is used to calculate a linear model to minimize residual error
- Allan Variance Testing, which is used to measure the in-run bias stability of accelerometers and gyroscopes, as well as angular random walk of gyroscopes and velocity random walk of accelerometers
- Applications of the Kernel-100, including platform stabilization, remote weapons stations, and ROVs (remotely operated vehicles)
- The forthcoming Kernel-300 for higher accuracy applications, which is expected to achieve an Angular Random Walk of 0.08 deg/√hour and an accelerometer bias in-run stability of 0.005 mg
The Kernel-100 features continuous built-in test (BIT), electromagnetic interference protection, and flexible input power requirements, and is well-suited to a wide range of unmanned systems applications. To find out more, read the full article on Inertial Labs’ website.
