First of all, the three specific elements are:
1, GPS terminal equipment (also known as GPS locator);
2. Transmission network (usually GPRS);
3. Position display platform (GPS positioning system).
Second, positioning is achieved in the following ways:
1, there is a GPS terminal, commonly known as GPS locator (locators are generally divided into wiring type, charging installation-free type and smart wearing type), and the telephone watch mentioned in the question belongs to smart wearing type GPS positioning terminal;
2. Put an IOT card in the locator. The main function of IOT card is to have GPRS traffic and transmit the location information obtained by the locator to the network platform through the network;
3. Location service software, the locator location information transmitted through the network is displayed in the platform software in the form of map or text through background latitude and longitude calculation, so that users can see it at a glance.
Third, the positioning operation method is:
1, GPS positioning watch needs to be installed with SIM card and turned on after charging. The specific installation method of SIM card is as follows:
2. Download and install the mobile phone application positioning software:
Search for related APP application software in the application mall, and log in through the account password.
When the positioning device is turned on normally and is active outdoors, enter the home page through the registered APP positioning software, and click "Real-time Tracking" to obtain the position information of the current watch.
