1. The difference between attitude sensor, gyroscope, acceleration, angular velocity and geomagnetic sensor

2. The difference between 3-axis, 6-axis and 9-axis gyroscopes

The attitude sensor itself contains three-axis gyroscope, three-axis accelerometer, three-axis electronic compass and other motion sensors.

The parameters detected by the gyroscope, acceleration, angular velocity, and geomagnetic sensor are different.

Three axes only have acceleration, six axes generally have acceleration and angular velocity, and nine axes have acceleration, angular velocity and gyroscope.

The gyroscope is also an angular velocity sensor. The physical quantities measured by geomagnetism, gyroscope and acceleration are different. The same sensor has at most 3 axes. Different sensors can be combined to form what we often call 6 axes or 9 axes. This combination of sensors can be called an attitude sensor.

You can get the answers to these questions by searching online. Geomagnetism measures the strength of the magnetic field, generally the earth's magnetic field. The direction is determined by the magnetic field. It is also called an electronic compass. The gyroscope measures angular velocity.

Are there any recommendations for 9-axis domestic attitude sensors?

QWE4562009 posted on 2022-8-15 16:53 Do you have any recommendations for domestic 9-axis attitude sensors?

Imported ones are not expensive, and high-precision or precision sensors are still far behind domestic ones. If there is no administrative requirement, there is no need to try it now.
