Embodiment Construction

[0027] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0028] The technical solutions provided by the embodiments of the present application may be applied in an application scenario of processing positioning log files of GNSS (Global Navigation Satellite System, Global Navigation Satellite System) satellites. Wherein, the positioning log file is also called Nmea (unified standard protocol for navigation equipment) log, and the positioning log file can be stored on the navigation equipment, and the navigation equipment can perform a series of data processing based on the positioning log file. For example, the stored location log files are larger location log files (location log files within a period of time), from which location log files of a specific time period (time range) may be intercepted. And, based on the intercepted positioning log file, a tra...

Abstract

The invention provides a processing method and device for positioning a log file, navigation equipment and a storage medium. The positioning log file processing method comprises the following steps: acquiring a to-be-processed positioning log file, wherein the positioning log file to be processed comprises time information; acquiring a first time range; wherein the first time range is a time range corresponding to a to-be-intercepted positioning log file; determining a second time range according to the time information, wherein the second time range is a time range corresponding to the to-be-processed positioning log file; judging whether the first time range is within the second time range or not; and if the first time range is within the second time range, intercepting a corresponding positioning log file from the to-be-processed positioning log file according to the first time range and the time information. The method is used for efficiently and accurately positioning log file processing.

Description

technical field [0001] The present application relates to the technical field of navigation, and in particular, relates to a processing method and device for locating log files, a navigation device, and a storage medium. Background technique [0002] For navigation equipment, real-time positioning is required during navigation, and satellite positioning log files will be generated during the process of positioning through satellites. Based on this location log file, some further data processing can be done. Before data processing, the location log file is usually intercepted, and then processed based on the intercepted specific log file. [0003] In the prior art, the interception of the location log file is manually completed, so the processing efficiency and precision are low. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a processing method and device for locating log files, a navigation device, and a storag...
