I was curious what would be written to the magnetometer calibration file if I disabled the sanity check, as a way of pursuing an understanding of whether the problem was my BeagleBone Blue hardware or the software running on it. For magnetometer calibration we use Earth's magnetic field as a reference. More measurements were made moving the sensor outside the calibration solenoid, but increasing the current in the solenoid by a factor of 30-50. Using a compass with a trusty old map is one of the best ways to navigate forests and hike mountains. Fastprk is an intelligent Parking Management System that allows cities and operators to manage parking resources more efficiently and parking operators to generate additional revenue. I don't know which compass app you have, but in the one I have there are similar settings for altering the sensitivity. The idea is to reduce the magnetism of the screws or whatever with a reversed field so that the magnetometer is not swamped and a calibration procedure (a couple of rotations about each axis or moving the tablet through a 3D figure 8) will work. For the 2-D calibration, the magnetometer was rotated 360° in the horizontal plane and then the heading was computed using the estimated SF and b. The LSM9DS1 is a versatile, motion-sensing system-in-a-chip. The four calibration registers -- an overall system calibration status, as well individual gyroscope, magnetometer and accelerometer values -- will return a value between '0' (uncalibrated data) and '3' (fully calibrated). teMperAture the transformation coefficients and the angles between the magnetic sensors can be measured in the temperature range –30 – +60 °c. ” This is a common problem. By automatic reading the magnetometer output the calibration is fast and accurate. I'm using Sparkfun Razor IMU 9DOF sensor which incorporates accelerometer, gyroscope, and magnetometer, for giving the Euler's angles (yaw, pitch, and roll). Learn more at Phidgets.
