In this article, we will teach you about the inertial measurement unit and its usefulness in our daily life. We will explain through the different elements that go into the composition of this much prized electronic object. Indispensable in the world of robotics for some and in the aeronautical industry for others, the inertial measurement unit seems to be essential in the progress of science and techniques since it is used in manufacturing and walking of many technologies invented by humans.
What is the inertial measurement unit?
The inertial measurement unit is an electronic device with 9 sensors whose job is to measure the orientation, the angular speed and the gravitational forces of a sensor, and this by combining the accelerometer, the gyroscope and the magnetometer. This electronic device thus born from the fusion of three sensors is used to detect and control the trajectory of the systems to which it is connected.
Therefore, it is used in the manufacture, launch and control of satellites in orbit. But it is most frequently used in the aeronautical world, to facilitate the maneuvering of civilian aircraft as well as military aircraft, drones and missiles. The inertial measurement unit, called in English imu sensor works by detection and with great precision. This makes this electronic component an essential element that we find all the time in the world of technology.
Types of inertial measurement unit
It is important to know at this level that there are two types of inertial measurement unit sensors. The first version consists only of acceleration and gyroscope detectors while the second contains the three sensors, that is to say, the type 1 components, in addition to the magnetometer.
Thus, with the first model, it is easier to detect the acceleration and the inclination that a machine takes or any driving force. However, with a small touch added to type 1, the type 2 inertial measurement unit allows, in addition to the functionality already existing with type 1, to measure the direction and intensity of a magnetic field.
