Abstract: Embodiments of this application provide a positioning method and apparatus. The method may include setting an ambiguity adjustment parameter for a mobile device, where the ambiguity adjustment parameter is used to record an ambiguity change status used to determine a virtual station observation value for the mobile device. The method may also include adjusting an observation value of a first primary datum station based on a first ambiguity adjustment parameter of the mobile device in a first serving cell to generate a first virtual station observation value, where the first primary datum station is a primary datum station of the first serving cell, and the first virtual station observation value is used to position the mobile device in the first serving cell; and sending the first virtual station observation value to the mobile device.

Abstract: Embodiments of this application disclose a method for updating a network RTK reference station network including: if there is a newly added node in a current reference station network, determining a position relationship between the newly added node and each node in the current reference station network; determining N target nodes in the current reference station network according to a preset rule based on the position relationship; determining, based on the N target nodes, M nodes connected to each of the N target nodes, where the M nodes belong to the current reference station network; and performing network construction on the M nodes and the newly added node according to a Delaunay triangulated network construction rule. According to the method for updating a network RTK reference station network, fast networking can be implemented and efficiency can be improved.
