Abstract

The invention discloses an object positioning method and device, a storage medium and electronic equipment. Applied to the field of maps, the method includes: obtaining the current inertial navigation data collected by the inertial navigation system for the target object in the current epoch and the current observation data collected by the positioning and navigation system; based on the current inertial navigation data and measurement relationship data, obtaining The first reference position information of the antenna phase center position; the double-difference observation equation constructed based on the current observation data and the virtual observation equation constructed based on the current inertial navigation data are combined to obtain the current ambiguity set through filter fusion; Obtain the second reference position information of the antenna phase center position from the target ambiguity subset determined in the current ambiguity set; use the state error between the second reference position information and the first reference position information to correct the current inertial navigation data to obtain the positioning result of the target object. The invention solves the problem of poor accuracy of object positioning results.

Description

technical field [0001] The present invention relates to the field of positioning and navigation, in particular to an object positioning method and device, a storage medium and electronic equipment. Background technique [0002] In order to achieve precise positioning of moving objects (such as vehicles, drones, mobile terminals, etc.), the commonly used positioning methods in related technologies are Global Navigation Satellite System (GNSS for short) and Inertial Navigation System (Inertial Navigation) System (INS for short) and other sensors to fuse the sensor data collected to assist positioning and navigation. [0003] However, in the above positioning process, due to the need to perform fusion calculations on different sensor data, positioning estimation errors will inevitably be introduced, resulting in poor accuracy of positioning results. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] Embodiments o...
