Modern phones are equipped with many useful features. Including, GPS navigation. This allows to determine the object’s location to within a few meters, Как пользоваться компасом?which is very convenient in an unfamiliar city.

The principle of the compass in the phone is quite simple. It determines the rotation angle of the mobile phone, giving data on the screen. It works based on GPS-Navigator, from which the signal arrives at the sensor in the phone. The digital compass reads the information and gives it to the user.

Data from the digital compass visible on the map GPS-Navigator. To determine the cardinal direction can be further installed on the phone dedicated application. With this compass you will easily be able to navigate in an unfamiliar city, finding the right objects.
