Abstract: A self-differential positioning method and apparatus, and a mobile device and a storage medium. The method comprises: acquiring a pseudo-range measurement value of a mobile device relative to a satellite at the current moment and a corresponding first differential correction value at a historical moment, wherein historical location coordinates of the mobile device at the historical moment are corrected according to the first differential correction value, and the historical location coordinates represent a virtual reference location of the current location of the mobile device (S115); and determining the current location coordinates of the mobile device according to the pseudo-range measurement value and the first differential correction value (S116). It is not necessary to set up a reference station and a mobile communication network, thereby reducing the complexity cost of a system. The method can be applied to a scenario where an area without an RTK support condition has a requirement for short-term relative positioning accuracy, or the method serves as a supplement for RTK technology to solve the problem of RTK signal transmission interruption, thereby realizing accurate positioning.
