摘要
GNSS观测数据的质量直接关系到GNSS的测量精度和可靠性。文章在周跳探测、相位平滑伪距等研究的基础上,从多路径效应、电离层延迟、电离层延迟变化率等方面对GNSS观测数据质量检核进行了研究,并编写了一款新的GNSS观测数据质量检核软件G-QC,实现了质量检核报告的可视化。该软件能兼容RINEX第2版及第3版。通过与TEQC(translation,editing and quality checking,TEQC)软件包的质量检核结果进行比对,验证了算法的正确性。利用所编制的软件G-QC实现了对GPS/BD双模接收机静态和动态观测数据的质量检核。
The quality of GNSS observation data directly relates to the accuracy and reliability of GNSS measurement. In this paper, based on the study of cycle slip detection and phase smoothing, the quality checking of GNSS observation data is analyzed in multipath effect, ionospheric delay and ionospheric delay variation, then a piece of software for GNSS data quality checking, G-QC, is developed. The visualization of the quality inspection report can be realized with the software G-QC, and the G-QC is compatible with RINEX II and RINEX III. The correctness of the algorithm is verified by the comparison between the quality checking results obtained with G-QC and that with the software TEQC（translation, editing and quality checking）. The quality checking of the static and dynamic observation data for the GPS/BD dual mode receiver has been realized with the developed software G-QC.
