The invention relates to the technical field of base station time service synchronization and positioning, and discloses a base station positioning method and device under a Beidou navigation system denial condition. The base station positioning method comprises the following steps: determining a first time calibration value through a locally generated synchronization signal data sequence and a first signal data sequence sent by a second base station and received by each first base station, and carrying out preliminary time calibration on the corresponding first signal data sequence based on each first time calibration value; and performing time calibration on the corresponding second signal data sequence by using a second time calibration value determined by a preset inter-base-station clock synchronization module to obtain a third signal data sequence, and further ensuring accurate time service between the base stations through two times of calibration. The calibrated signal arrival time is more accurate, a
