Problems solved by technology

2G positioning and NB-IoT positioning belong to base station positioning. Base station positioning is to obtain the location information of mobile terminal users through the operator's network. After the mobile terminal is inserted into the SIM card and turned on, it searches for surrounding base station information and locates based on the acquisition of base station location information. However, this positioning method cannot obtain the location information of the base station in a remote area without a base station, and its positioning error is relatively large, and the error of a single base station is 100-500 meters
In addition, the GPS module, Beidou module, NB-IoT and 2G modules in the existing positioning technology are usually in a continuous working state, and the system power consumption is relatively high
