The invention discloses a positioning data processing method and apparatus, and a computing device. The positioning data processing method comprises the steps of acquiring positioning data for a target object, wherein the positioning data comprise data of a series of positioning points of the target object in the moving process; converting the positioning data into a preset coordinate system; calculating the distance between the adjacent positioning points based on the position relation of the adjacent positioning points under a preset coordinate system; determining motion information of the target object based on the distance between the adjacent positioning points; judging whether the determined motion information is consistent with the motion information contained in the positioning point data or not; and if the determined motion information is consistent with the motion information contained in the positioning point data, determining that the positioning data is reliable. According to the processing scheme of the positioning data, the reliability of the positioning data can be determined without extra data support.
Description
technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a solution for processing positioning data. Background technique [0002] Global Navigation Satellite System (GNSS, Global Navigation Satellite System) is a positioning technology that is currently used in both military and civilian applications. At present, the navigation satellite systems that provide services internationally mainly include GPS in the United States, GLONASS in Russia, GALILEO in the European Union, and Beidou satellite navigation system in China. The user terminal can acquire signals of multiple navigation satellites by using corresponding receivers. Through physical laws such as relativistic effects, information such as the geographic location, speed, and direction of the user terminal can be further calculated. [0003] Under the existing technology, unreliable GNSS signal data often occurs, such as coordinate point drift, obvious devia...
