Abstract: The present disclosure relates to a method and an apparatus for establishing a positioning network. The positioning network includes a data processing center and at least one reference station, and one node in the positioning network represents one reference station. The method includes: determining, if a first historical positioning network capable of forming a new positioning network with a newly added node exists in a network list of the data processing center, whether the newly added node forms the new positioning network with the first historical positioning network; and determining, if the network list does not exist in the data processing center, whether the newly added node is capable of forming a new positioning network with nodes in a first node information list. Before network real-time kinematic (RTK) is formed, a user can use a single-baseline RTK positioning service. The network RTK is formed once a networking condition is met.
