    Abstract
  • The data quality of GNSS observations is the premise of ensuring high-precision positioning of GNSS. In order to improve data quality, data preprocessing of GNSS observations is required. Currently, TEQC software developed by UNAVCO Facility is widely used. However, TEQC is an imperative in DOS environment, there is no graphical user interface, and human-computer interaction is poor. The generated drawing result files need to be processed by visual software such as QCVIEW, but these saftwares can not conduct graphical analysis of the compact 3 format file generated by TEQC 2013.3.15 or higher version. Therefore, based on MATLAB GUI, a set of visual interface software (TEQCplot View) for compact 3 result files is developed. The experimental results show that the software has stable performance and can realize visualization analysis of different result files.
