Weather setting is not allowed for Tianyan car navigation.

Tianyan car navigation can set the weather in the following ways:

Turn on gps positioning and connect automatically where there is a signal, and the corresponding weather dynamic effect will be displayed.

Use GPS (Global Positioning System) and electronic map for car navigation. It can tell the driver the shortest or fastest route to the destination conveniently and accurately, and it is a good helper for the driver.

Geosynchronous satellites located above the earth were originally used for military and aviation navigation. The U.S. government relaxed the restrictions on the use of synchronous satellites in the 1980s, which opened up a new world for its wide adoption. Subsequent commercial communication satellites greatly improved the accuracy and coverage of communication satellites.
