Overview
About the IM26
The IM26 IMU module fuses data from a MEMS accelerometer and gyroscope with GNSS RTK data to deliver high-performance attitude measurement, with roll and pitch accurate to within 0.02 degrees.
This level of accuracy has found the IM26 widespread use in industrial applications such as machine control, robotics, tilt surveys, AHRS, and dead reckoning. The IM26 is protected under various international patents (US US11409001B2, Chinese CN110017849B, etc.).
