POSITIONING METHOD, TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/257887
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of satellite positioning, and specifically discloses a positioning method, a terminal (10), and a storage medium. Preprocessing raw observation data to obtain processed data (101); if the processed data does not satisfy a preset positioning condition, then, according to a Doppler observation value in the processed data, generating pseudo-carrier data, and constructing a carrier observation model on the basis of the pseudo-carrier data (102); according to the carrier observation model, constructing a target observation model (103); and determining location information by using the target observation model (104). Thus, positioning processing on the basis of a carrier phase observation value can be implemented, greatly improving positioning accuracy and positioning precision.
