Embodiment Construction

[0034] Hereinafter, the present invention will be further described in conjunction with the drawings and embodiments. figure 1 It is a system structure diagram for merging multi-source Rinex observation files in the present invention, including an observation file Header content extraction module, an observation file sorting module, an observation file data filtering module, an OBS TYPES normalization processing module, and an observation data merging module.

[0035] figure 2 For the present invention merges the method flowchart of multi-source Rinex observation file, comprises the following steps:

[0036] Step 1, the observation file header content extraction module scans all the observation files to be merged, and extracts the header description information of each observation file, which mainly includes the time range described in the observation file, the description rules of OBS TYPES, etc.

[0037] Step 2, according to the header description information of all observ...

Abstract

The invention provides a method for combining multi-source Rinex (Receiver Independent Exchange Format) observation files. The method comprises the following steps that: S1: an observation file Headercontent extraction module scans an observation file to be combined and extracts Header description information; S2: an observation file sorting module sorts the observation file according to a time sequence; S3: an observation file data filtering module filters the data in repeated time periods; S4: an OBS TYPES normalization processing module carries out combination and resorting and records a corresponding relationship between the original OBS TYPES and the combined OBS TYPES of each observation file; S5: an observation data combination module reads the observation files which are sorted insequence, and each piece of epoch observation data in the observation file is scanned and rearranged and output, wherein the repeated time periods of the observation files are filtered; and S6: the combination of the multi-source Rinex observation files is finished. The method is high in combination speed.

Description

technical field [0001] The invention relates to the technical field of data merging, in particular to a method and system for merging multi-source Rinex observation files. Background technique [0002] Rinex (Receiver Independent Exchange Format, receiver-independent exchange format) is a format specification for storing base station GNSS (Global Navigation Satellite System, Global Navigation Satellite System) observation data, and is a commonly used in GPS measurement applications. The standard data format, each Rinex observation file will save the observation data received by the base station (specifically GNSS ground-based augmentation station) for a period of time - usually 15 minutes, 1 hour and 1 day. Since the arrangement of observation data types in the Rinex file is free, that is, different recording terminal equipment, usually base station receivers, Ntrip (a protocol for RTCM network transmission through the Internet) real-time stream receiving device will record ...
