In order to meet the reliability, high precision and timeliness requirements of GNSS observation data products for earthquake monitoring and prediction, the original The quality evaluation of observation data is extremely important. This document provides evaluation indicators with clear indicative significance and the calculation method of the indicators, and objectively evaluates the quality of observation data. Improve the quality of GNSS raw observation data and find problems in the observation data, including the impact of changes in observation equipment and observation environment on the data. The impact of observation quality provides a reference for GNSS observation data post-processing analysis and station operation and maintenance. According to the earthquake monitoring network operation quality evaluation business listed in DB/T 61-2015 "Earthquake Monitoring and Forecasting Professional Standard System Table" Special standards, "Evaluation Specifications for Seismic Observation Data Quality" is a series of standards for quality evaluation of observation data of various networks. This document is the One of a series of standards. Specification for quality evaluation of earthquake observation data GNSS observations1 ScopeThis document specifies the content, evaluation indicators and methods of the crustal deformation network global navigation satellite system (GNSS) observation data quality evaluation. Requirements for grade assessment and presentation of evaluation results, etc. This document is applicable to the quality evaluation of GNSS observation data of crustal deformation network. The quality evaluation of other GNSS observation data can refer to this document. use.2 Normative referencesThis document has no normative references.3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 fiducialstation Conduct long-term continuous observation of satellite navigation signals and transmit the observation data to the data center in real time or at regular intervals through communication facilities.
