Title:
METHOD AND DEVICE FOR SWITCHING VIRTUAL REFERENCE STATION IN REAL TIME KINEMATIC POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/121623
Kind Code:
A1
Abstract:
A method and device for switching a virtual reference station in a Real Time Kinematic positioning system are provided. The method comprises: obtaining reference station networking change information (S110); obtaining prediction information according to the reference station networking change information, wherein the prediction information comprises switching from calculating a virtual reference station of a mobile station according to a first reference station combination to calculating a virtual reference station of a mobile station according to a second reference station combination (S120); calculating a first virtual reference station according to the first reference station combination, and calculating a second virtual reference station according to the second reference station combination (S130); and providing the mobile station with at least one of information about the first virtual reference station and information about the second virtual reference station, such that the mobile station performs positioning correction (S140). The method and device for switching a virtual reference station in a Real Time Kinematic positioning system of the invention can effectively reduce the impact of network reconfiguration of reference stations in a Real Time Kinematic positioning system on a positioning service provided thereby, meeting demands of uninterrupted high-precision positioning.
