What is the accuracy of GPS positioning for tens of yuan.mini gps tracker

　　With the maturity of the GPS positioning market, the price of GPS is becoming increasingly transparent. At the same time, a group of GPS locators that cater to customers' low-cost needs have emerged. LBS locator terminals that impersonate GPS locators are often priced at tens of yuan. Due to their low price, their appearance is no different from ordinary GPS locators, and even the word GPS is marked on the shell, misleading many consumers.

　　The so-called LBS locator refers to a device that does not have a satellite positioning chip inside. The device uses a built-in traffic card signal to determine its position, which belongs to base station positioning. The accuracy of base station positioning is affected by the density of the base station at the location. Therefore, sometimes when in the city, it feels like the positioning error is only a few tens of meters, but sometimes if the vehicle drives to a rural area, the positioning error becomes a few hundred meters. If it is in a more remote place, There may even be an error of several kilometers. This is determined by the principle of the base station locator.

　　The so-called base station positioning refers to the device determining the distance between the device and the base station through the signal of the built-in mobile phone card. If more than three base stations can be searched around, the basic location information of the device can be determined. If there are fewer surrounding base stations, the error will increase, which is why the error of the base station positioning device varies greatly
