Smallest Size Triaxial MEMS North Seeker
The [u]inertial measurement unit[/u] works by detecting the current acceleration using one or more accelerometers. IMUs use one or more gyroscopes to detect changes in rotation properties such as pitch, roll and yaw. Some IMUs on drones include magnetometers, which are primarily used to assist in calibration to prevent directional drift.
Onboard processors constantly calculate the drone’s current position. First, it integrates the perceived acceleration with an estimate of gravity to calculate the current velocity. The velocity is then integrated to calculate the current position.
To fly in any direction, the flight controller collects IMU data for the current position and then sends the new data to the motor Electronic Speed Controller (ESC). These electronic speed controllers send the thrust and speed signals needed for the quadrotor to fly or hover to the motor.

If the drone flies erratically, recalibrate the IMU on a flat surface. Sometimes you need to calibrate the IMUs multiple times. You should also check the drone manufacturer’s website for firmware updates to address any issues within the flight controller. If there are other problems, then the drone could have a hardware failure in the IMU or flight controller.

A triaxial MEMS north seeker, also known as a triaxial magnetometer, is a type of sensor used to detect the Earth’s magnetic field and determine the direction of true north. These sensors are commonly used in various applications, including navigation systems, drones, robotics. [b]Ericco[/b] offers you the world’s smallest 3-axis MEMS north finder with affordable price.
