CORS data quality detection and early warning system based on TEQC

Abstract

The invention discloses a CORS data quality detection and early warning system based on TEQC. The CORS data quality detection and early warning system comprises a quality detection module and an earlywarning module. The quality detection module is an observation data automatic detection module loaded with TEQC software and can call the TEQC software through Visual C # to automatically carry out quality detection on observation data, process a quality detection report generated by the observation data by utilizing the TEQC software, and automatically extract a data efficiency, a multi-path effect and a ratio of an observation value to a cycle slip number to analyze the quality of the observation data; and the early warning module is used for extracting data in the quality detection report,analyzing and judging the data and providing a CORS reference station data quality condition in real time. According to the method, the quality of the CORS reference station observation data is automatically checked by calling TEQC software, mass data management is achieved, and the real-time condition of the CORS reference station observation environment can be reflected to a user in time.

Description

technical field [0001] The invention belongs to the technical field of satellite communication network data processing, and in particular relates to a TEQC-based CORS data quality detection and early warning system. Background technique [0002] The continuous normal operation of reference stations is the most critical part of whether the entire CORS system can be effective. The quality of CORS data is one of the main factors affecting the accuracy of CORS measurement. The quality of observation data can be reflected from indicators such as data efficiency, cycle slip ratio, multipath effect delay, ionospheric delay change rate, and signal-to-noise ratio. Generally speaking, these indicators have mutual influences. Together, they affect the quality of observation data. TEQC software, developed by UNVACO Facility, is currently the most commonly used GPS / GLONASS data quality analysis software, and the new version of TEQC can already process data from other satellite systems ...

AI Technical Summary

Problems solved by technology

[0004] TEQC is currently internationally recognized as an excellent GNSS data processing software, which has functions such as data format conversion, data editing, and quality inspection. However, TEQC software needs to implement parameter setting in the form of a command line in a DOS environment and perform a series of data processing. Operation, poor interactivity, no visualization, inconvenient operation, etc.
