Mobile phone compass

Mobile phone compass is a kind of software installed in the mobile phone, which needs a hardware module installed on the main board of the mobile phone to support its operation, and can display different directions and pitch angles according to the position of the mobile phone.

Mobile phone compass, that is, mobile phone electronic compass, is a software and hardware of mobile phone. According to the position of the mobile phone, the display direction and pitch angle can be different.

According to the reading of the electronic compass, the map automatically rotates to the direction convenient for users to read. Very suitable for people who are not good at using maps. In addition, like the traditional compass, you can roughly estimate your position according to landmarks (experienced people use it like GPS), control the direction of travel and so on.

Electronic compass, also called digital compass, is a method for modern people to determine the North Pole by using geomagnetic field and electronic technology. The magnetoresistive sensor produced by modern advanced processing technology provides a powerful help for the digitalization of compass. At the beginning of 2 1 century, electronic compasses made of magnetoresistive sensors and fluxgates were mainly used. Although GPS is widely used in navigation, positioning, speed measurement and orientation, its accuracy is greatly reduced or even unusable because its signals are often blocked by terrain and objects. Especially in urban areas with high-rise buildings and forest areas with dense vegetation, the effectiveness of GPS signals is only 60%. Moreover, at rest, GPS can't give course information.

In order to make up for this deficiency, the method of integrated navigation and positioning can be adopted. Electronic compass products are designed to meet the needs of users. It can effectively compensate the GPS signal, ensure that the navigation and positioning information 100% is effective, and it can work normally even if the GPS signal is out of lock, so as to achieve "missing the star without losing direction".
