Hello, I am looking for a sensor, with which ist is possible to measure the acceleration in two dimesnion. First i would like to describe the application: A carriage can be moved by linear motors in two ("horizontal") directions, indivudially or simultaneously. With the acceleration data, the best estimation of the position shall be calculated. Therefore it is necessary that the acceleration is only measured in the two directions. Because it is not possible, to mount the sensor exactly (sensor coordinatesystem equal to carriage coordinatesystem) I assume that there is "Sensor Fusion" or at least some calculations necessary. As far as I know, to compensate gravity from the accelerometers as good a possible, there are gyros AND Magnetometers necessary. The output data rate (ODR) should be at least 400 Hz. The BNO-055 has 9 axes, but only a ODR auf 100 Hz. The BMI088 has higher ODR, but no magnetometers. I think the problem is, that it is not possible to build a magnetometer with higher ODR. Is this right? What is the best sensor to use for my application? What steps (calibration) has to been taken, to ensure that the acceleration measurement is as good as possible? I hope, somebody can help me. Thanks in advance
