What's mobile navigation for? Do you need traffic or do you need to charge?

Mobile navigation takes the user from the current location to another desired location through the navigation function of the navigation mobile phone. The use of mobile navigation needs traffic, and the traffic needs to be charged. Mobile navigation itself does not charge.

Mobile navigation is the satellite mobile navigation. Different from the mobile phone electronic map, it can tell the location in the map and where to go, choose the best route between the location and the destination, and prompt to turn left or right during the journey.

Mobile navigation on the market now falls into three categories:

The first category is real GPS navigation through satellites in space, with an accuracy of 3-5 meters;

The second is rough navigation through the base station network, which is called CELLID navigation. This kind of navigation is not as accurate as satellite GPS navigation, and the general positioning error is 100 meters.

The third category is AGPS+CELID+GPS positioning, which is the most accurate navigation. CelID positioning is the default setting indoors. Use AGPS to search the star map outdoors to achieve fast positioning, and then GPS automatically switches to high-precision positioning navigation.
