BQC: Multi-GNSS Quality Check Method Toolkit
Liu Hui-cu · Geomatics & Spatial Information Technology · 2014
A novel GNSS data quality check software BQC is developed on MATLAB which can process data of four dominant navigation satellite systems-GPS,Beidou,GLONASS and Galileo-and data recorded in RINEX format version 2 and 3. BQC can work in two modes: single-file processing mode and batch processing mode. It generates satellite angle position,multipath error,ionosphere delay,SNR,carrier phase slips,as well as a summary report; in addition,data quality of different observation files is compared and shown in figure files in batch processing mode. It is shown in this paper that BQC has better compatibility,algorithm priority and visualization than TEQC. With the development of GNSS and popularization of RINEX format version 3,BQC is going to be a powerful toolkit for GNSS construction result check.
