Kind Code:
A1
Abstract:
A positioning method and apparatus, and an electronic device and a storage medium. The method is applied to an unmanned vehicle, i.e., an unmanned driving device or an autonomous driving device. The method comprises: receiving first positioning data, which is sent by a reference station by means of a radio station, wherein the radio station is erected within a preset range of the reference station and is located between the reference station and an operation area of a first vehicle (S301); and processing the first positioning data and the current positioning data of the first vehicle by using real-time kinematic carrier phase difference technology, so as to obtain first positioning information of the first vehicle (S302). By means of the method, the first vehicle can obtain a centimeter-scale positioning precision within a short period of time without increasing construction costs and maintenance costs of the reference station, such that the positioning stability of the first vehicle is improved, and the operation efficiency of the first vehicle is further improved.
