In the old days when there was no compass, it is said that people looked for the direction while looking at the Big Dipper floating in the night sky to find their way. However, those of us who live in the 21st century can easily find out which direction we want to go if we learn how to read a compass with a smartphone in our hand. This time, let’s take a closer look at how to see the compass displayed through the app. 나침반 보는법

If you click the M button in the app, it will change to T. Did you know that the Earth has two North Poles?
Magnetic North
True North
True North means the direction where the North Star is. Magnetic north refers to the location where the compass needle is pointing. Earth has a strong magnetic field, which means that the magnetic north the compass needle points to is not actually true north. In other words, there is a big difference between the east, west, south, and north that you see in reality and what is displayed on your device.
Distance difference between true north and magnetic north
Compass
It is known that the distance difference between each two points is about 1,000 km. It is known that when a compass is measured looking north from Seoul, there is a difference of about 6.5 degrees, and this declination is changed by the earth’s magnetic field.
In order to reduce the difference between true north and magnetic north, airplanes and ships often use gyro compasses, but since it is impossible in mobile phone applications, it is okay to simply understand that there is such a thing. In fact, there will be very few cases where we carry a compass and go to the end of the North Star.

When you compare the Galaxy mobile phone and the iPhone, you can see that they point in similar directions, but they do not match 100%. To start with the conclusion, the iPhone has a more sensitive sensor and accuracy, giving the impression of high accuracy. It does not require sensor adjustment like the Galaxy model, and the compass reading method is easily solved in the basic application itself, so this function is still the iPhone’s victory.
