The invention discloses a satellite positioning interference detection method and an apparatus wherein the method comprises the following steps: within a preset time period, receiving a satellite positioning signal through a satellite receiving antenna; according to the satellite positioning signal, outputting the positioning result information wherein the positioning result information contains information whether the positioning is a success or not; when the positioning information tells that a positioning failure occurs, obtaining the number of satellites which meet the first preset conditions; and if the number of the satellites that meet the preset conditions exceeds the preset number, then, determining that there exists satellite interference. According to the invention, through the determination that when positioning fails in a preset period, the number of the satellites that meet the preset conditions exceeds the preset number, satellite positioning interference could be detected, and if these determination conditions are satisfied, it is possible to determine satellite positioning interference so as to provide reference to positioning abnormity treatment.
