METHOD AND DEVICE FOR SWITCHING VIRTUAL REFERENCE STATION IN REAL TIME KINEMATIC POSITIONING SYSTEM

摘要

Embodiments of the present invention disclose a virtual reference station switching method and device in a real time kinematic system, and the method includes: obtaining networking change information of a reference station network; obtaining prediction information based on the networking change information of the reference station network, where the prediction information includes: a reference station combination used to calculate a virtual reference station of a mobile station is switched from a first reference station combination to a second reference station combination; obtaining a first virtual reference station through calculation based on the first reference station combination, and obtaining a second virtual reference station through calculation based on the second reference station combination; and providing at least one of first virtual reference station information or second virtual reference station information to the mobile station, so that positioning correction is performed on the mobile station. According to the virtual reference station switching method and device in the real time kinematic system provided in the embodiments of the present invention, impact of networking reconstruction of the reference station network in the real time kinematic system on a positioning service provided by the real time kinematic system can be effectively reduced, and a requirement for uninterrupted high-precision positioning can be met.
