GPS Automotive navigation system.gps tracker device Solution

　　Having a GPS system alone is not enough. It can only receive data sent by GPS satellites, calculate users' three-dimensional position, direction, and motion speed and time information, and has no path calculation ability. If the GPS receiver in the user's hand wants to realize the route navigation function, it also needs a complete set of Automotive navigation system including hardware equipment, electronic map and navigation software.

　　The hardware of the GPS navigator includes components such as chips, antennas, processors, memory, screens, buttons, speakers, etc. However, as of now, there is not much difference in hardware between GPS car navigators in the market, with the main difference being concentrated in built-in software and maps. Here, it should be noted that people are accustomed to caring about which map is pre installed in the navigator, which actually confuses the difference between maps and software. The so-called map is actually just data, while software is a search engine. How can the huge data integrated by various geographical information in maps be used by users? How can it be reflected in the navigation interface? This needs to be achieved through software. Therefore, navigation maps cannot be separated from the support of software, and even an excellent software system without detailed map data is useless.

　　To summarize, a complete GPS car navigator is composed of 10 main parts: chip, antenna, processor, memory, display screen, speaker, buttons, expansion function slot, electronic map, and navigation software.
