When a GPS positioning terminal is made of hardware and software for vehicle positioning, it is called on-board GPS, but positioning alone is not enough. We also need to transmit the positioning information to the alarm center or the vehicle GPS holder, which is called the third party. Therefore, the GPS positioning system also includes GSM network communication (mobile phone communication), which sends the satellite positioning information to the third party by SMS. The short message message is interpreted by the microcomputer, and the vehicle position is displayed on the electronic map. In this way, vehicle GPS positioning is realized.

　　At the same time, install the corresponding detection sensor on the vehicle, and use the GSM network communication function of vehicle GPS positioning to send the anti-theft alarm information to a third party, or send the alarm phone and short message directly to the owner's mobile phone to complete the vehicle GPS anti-theft alarm. It can be seen here that the GSM network part of vehicle GPS positioning is actually a smart phone, which can communicate with a third party, and can also send information such as the vehicle being robbed, the driver being hijacked, or kidnapped to a third party.

　　Therefore, vehicle GPS positioning is positioning, anti-theft and anti-theft.

　　Similar to vehicle GPS terminals are positioning mobile phones, personal locators, etc. GPS satellite positioning requires third-party positioning services, so different monthly/annual service fees should be paid.

　　At present, all GPS positioning terminals have no navigation function. Because additional hardware and software are needed, the cost increases.

　　The car GPS ads we saw on TV are completely different from the car GPS mentioned above. It is a GPS navigation product. When navigation is needed, the first thing to do is to locate, which is the starting point of navigation. This is different from the real GPS positioning. It cannot transmit the positioning information to the third party and the holder because the navigator lacks the mobile phone function. For example, if you put the navigator in your car and your friend borrowed the car, and the navigator cannot send you a message, you cannot find the location of the vehicle. Therefore, the navigator cannot locate.

　　You said I bought a navigation mobile phone, right? Think about it. If you left the navigation mobile phone in the car, now the car has been stolen, would that mobile phone call you or send a text message to a third party? It needs people to operate. Therefore, the current navigation terminals have no positioning function.

　　The navigation terminal can navigate the route, so that you won't get lost in a strange place, draw a route to let you reach the destination, tell you your current position, and the surrounding facilities, etc.
