摘　　要：GNSS数据质量的好坏直接影响着定位的精度和可靠性。针对目前GNSS数据质量分析的主流软件大多操作复杂,需要有一定科研基础,并且每个软件有自己的侧重点,有的不支持四系统,有的不支持可视化。从实际出发,设计并实现了一套多GNSS数据质量全流程分析软件,可以满足从卫星端、传播路径到接收机端的多GNSS数据质量分析要求。The quality of GNSS data directly affects the accuracy and reliability of positioning.At present,most of the mainstream software of GNSS data quality analysis is complex and needs some scientific research foundation,and each software has its own focus,some do not support four systems,some do not support visualization.In this paper,we design and implement a multi-GNSS data quality analysis software,which can meet the requirements of multi-GNSS data quality analysis from satellite,propagation path to receiver.
