Which sensors does a drone use to stabilise its flight attitude?
A minimum of electronic components are installed in every drone in order to achieve the desired smooth flight results.
Rotation rate and acceleration sensors can be used to analyse and compensate for changes in the drone's position in space.
The orientation of the drone is determined by the compass, which is orientated to the earth's magnetic field.
Finally, the GPS sensor data is used to maintain the correct horizontal position.
The correct height above ground is maintained by an air pressure sensor.
The flight attitude can only be stabilised by compensating for the relative movements recorded by the angular rate, acceleration, compass, air pressure and GPS sensors. The better this is achieved, the more precise the flight attitude controller and the better the drone's hovering position can be maintained - a sign of quality.
