Title:
POSITIONING METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/160036
Kind Code:
A1
Abstract:
A data processing method and apparatus, and a device (1000) and a storage medium, which are mainly applied to the field of electronic maps. The method comprises: acquiring first actual observation data (22, 32, 42), second actual observation data (24), the actual position of a target reference station (11, 23) and the actual positions (33, 43) of N satellites (S101, S201); determining an initial estimated position (26, 35, 45) of a terminal (21, 31, 41, 71) according to the first actual observation data (22, 32, 42) and the actual positions (33, 43) of the N satellites (S102, S202); according to the second actual observation data (24), the actual position of the target reference station (11, 23) and the actual positions (33, 43) of the N satellites, determining a first system positioning error (27) corresponding to the initial estimated position (26, 35, 45) of the terminal (21, 31, 41, 71) (S103, S203); and adjusting the initial estimated position (26, 35, 45) of the terminal (21, 31, 41, 71) according to the first system positioning error and the first actual observation data (22, 32, 42), so as to obtain a target position (28) of the terminal (21, 31, 41, 71) (S104). Therefore, the position positioning accuracy of the terminal (21, 31, 41, 71) can be improved.
