The GPS locators shown on the service platform are "offline" and "out of date" in fact, in both cases. GPS locator offline is due to the phone card debt, improper installation, the signal can not be sent and other reasons; and GPS locator expired because the platform service expired need to pay.
Therefore, the GPS locator expired should be to pay the platform fee instead of paying the card fee. Maybe we all have questions about this: What is the platform fee? Why pay the platform fee?
Platform fees plainly check the car service platform charges. After the GPS locator receives the signal sent by the GPS satellites, the locator sends the signal information to the Internet server for analysis, after parsing, it can obtain the latitude, longitude, speed, time and other information of the vehicle. After the user logs in to the service platform Can see this information. The platform is equivalent to a data processing center, constantly analyzing the satellite signals sent by the locator.
