The network information includes: the network comprises the following components of network name, type and signal strength, wherein the type comprises a satellite network, a mobile internet (3G/4G/5G) network, a WIFI network and the like.
Determining the use environment of the mobile terminal according to the network information;
The use environment can be preset, and includes four types: indoor 1, indoor 2, outdoor 1 and outdoor 2.
Indoor 1: the system can be connected with a satellite network, a WIFI network (the signal intensity is more than or equal to-80 dbm) and a mobile internet (the signal intensity is more than or equal to-80 dbm);

whether data in each piece of position information is deviated or not can be judged through all pieces of position information obtained by positioning each target network, an average value of the position data in all pieces of position information can be calculated, when the data in the piece of position information and the average value exceed a preset threshold value, the data in the piece of position information is judged to be deviated, and otherwise, the data in the piece of position information is judged not to be deviated. Whether the data in the position information are deviated or not can be judged by calculating whether the self-deviation of the data in each position information in the preset time exceeds a preset threshold value or not, if the self-deviation exceeds the preset threshold value, the data in the position information are judged to be deviated, and if not, the data in the position information are not deviated.
