Zusammenfassung:	The invention relates to the field of Internet of Things, and provides a positioning method based on NB-IoT and AGPS aiming at the problem of low efficiency of acquiring AGPS data through an NB-IoT network in the prior art. The method comprises the following steps of: a positioning module carries out positioning to obtain satellite positioning data and satellite searching data and sends the satellite positioning data and the satellite searching data to an application server for storage through an NB-IoT gateway; the application server acquires positioning auxiliary data; a data processing module calculates according to the satellite positioning data and satellite searching data of a current NB-IoT positioning terminal and the satellite positioning data and satellite searching data in a storage module to obtain a number of a satellite which can be searched in an area where the NB-IoT positioning terminal is located and the probability of which is larger than a preset probability, the positioning auxiliary data
