What is a gyroscope? Easily explained
The gyroscope, also called a gyrocompass, was invented in Tübingen in 1810. But what exactly is a gyroscope? And what does your smartphone have to do with it? We have the answers in this practical tip for you.
Gyroscope supports GPS
A gyroscope is a sensor with which the exact position can be determined. A gyroscope rotates quickly in a movable bearing. The position of the gyro remains unchanged due to the rotational forces, even when the phone is moving.
- Changes in direction can be precisely determined using the gyroscope. If this information is combined with route measurements, your current location can be determined.
- If you drive through a tunnel, for example, in which no GPS signal is available, the gyroscope takes over and provides the missing information.
- The ISS space station uses the gyrocompass to determine position in space.
- In model aircraft, the gyroscope is used to stabilize the control against wind.
- Many smartphones, such as the Samsung Galaxy S7 or the Huawai P10, already have a built-in gyrocompass.
- If you have an Android device, check under "Settings" and "Display" whether you can find the item "Horizontal calibration". Then your device has a gyroscope.
- There are also various apps that you can use to find out if your device is equipped with a gyrocompass.
Gyroscope for more fun
The motion sensor is not only used for navigation. Game apps such as Pokémon GO also access it.
- The gyroscope extends the control options of the games.
- For example, you can move the game character on the display by tilting the smartphone.
If you do not want to use your smartphone for navigation, you can use a navigation device. The robust devices are quite expensive, but a big advantage is the longer battery life. So you will be guided safely to your destination.
