It is difficult for a gyroscope to stand on the ground when it does not rotate. The left and right directions in the aircraft are called roll, the front and rear directions in the aircraft are called pitch, and the vertical direction is the Z axis. The three axes of the three-axis gyroscope, three-axis accelerometer and three-axis geomagnetic sensor refer to the left and right of the aircraft, and the vertical up and down in the front and back directions, which are generally represented by XYZ. So what is a three-axis gyroscope, a three-axis accelerometer, a three-axis geomagnetic sensor, and a barometer? What role do they play in the aircraft? What are the three axes? The current flight control system uses an IMU, also known as inertial measurement unit, which is composed of three-axis gyroscope, three-axis accelerometer, three-axis geomagnetic sensor and barometer.

For flight control, it is necessary to know the current status of the aircraft, such as three-dimensional position, three-dimensional velocity, three-dimensional acceleration, three-axis angle and three-axis angular velocity. The flight control system is mainly used for flight attitude control and navigation. It is undeniable that the development of flight control technology is the biggest driver of UAV changes in this decade.įlight control is the abbreviation of flight control system, which can be regarded as the brain of aircraft.

In a few years, UAVs have flown from military applications far away from people’s vision to ordinary people’s homes. A large number of professional talents in automation, mechanical electronics, information engineering and microelectronics have been invested in UAV research and development. Nowadays, with the development of chip, artificial intelligence and big data technology, UAV has begun the trend of intelligence, terminal and clustering.
