Those who have used the car GPS locator know that if the device wants to be used normally, a SIM card must be configured in the device, and the card is activated and can be used normally. Why must the GPS locator be equipped with a SIM card in order to locate and track the vehicle? It is not difficult to understand, knowing the positioning principle of the GPS locator.
The GPS locator is a terminal with built-in GPS module and mobile communication module, which is used to transmit the positioning data obtained by the GPS module to a server on the Internet through the mobile communication module (gsm/gprs network), so that the terminal position can be checked on the computer or mobile phone.
According to the positioning principle of gps locator, it can be seen that the locator obtains the satellite signal to calculate the latitude and longitude, and then upload the latitude and longitude to the server through the network, the server analyzes the specific location, and then people through the mobile phone or computer to the server to query the location of the locator; If there is no sim card, then the latitude and longitude of the device can not be issued, and we can not query the location of the device, so there is no GPS locator without a sim card;
Therefore, why should the car GPS be configured with a SIM card? It is clear that it is to transmit data. If the SIM is out of charge or cannot be used for other reasons, the device will be displayed offline on the monitoring platform. In addition, some GPS positioning devices have a monitoring function, which can be monitored by dialing the phone number of the SIM card on the device.
