Abstract

This work presents recent and ongoing updates to the free and open-source advanced interactive multi-purpose package for processing and analysing Global Navigation Satellite System (GNSS) data, named GNSS-Lab Tool suite (gLAB). The updates have been performed in the framework of two projects funded by the European Space Agency (ESA), namely, the “gLAB upgrade for European Geostationary Navigation Overlay System (EGNOS) Data processing” and “Upgrade of gLAB Tool for Double Frequency Multi-Constellation (DFMC)”. We examine various sets of results obtained with actual data using the Satellite Based Augmentation System (SBAS) corrections and the Differential GNSS (DGNSS) mode. Specifically, we introduce the Global Monitoring System (GMS) that routinely assesses the performance of the SBAS and DGNSS solutions using multiple station networks. That is, the Stanford-ESA integrity diagram, the Worst Integrity Ratio (WIR) maps, continuity risk, among other types of performance monitoring. Lastly, we present the ongoing update to the gLAB tool that focusses on the implementation of multi-frequency and multi-constellation data processing capabilities.

GNSS实验室工具套件(gLAB)更新:SBAS, DGNSS和全球监测系统

这项工作介绍了用于处理和分析全球导航卫星系统(GNSS)数据的免费和开源高级交互式多用途软件包的最新和持续更新，称为GNSS-实验室工具套件(gLAB)。这些更新是在欧洲航天局(ESA)资助的两个项目框架内进行的，即“欧洲地球静止导航覆盖系统(EGNOS)数据处理的gLAB升级”和“双频多星座(DFMC) gLAB工具升级”。我们研究了使用卫星增强系统(SBAS)校正和差分GNSS (DGNSS)模式的实际数据获得的各种结果集。具体来说，我们介绍了全球监测系统(GMS)，该系统使用多站网络定期评估SBAS和DGNSS解决方案的性能。也就是说，斯坦福- esa完整性图、最差完整性比(WIR)图、连续性风险，以及其他类型的性能监控。最后，我们介绍了对gLAB工具的持续更新，重点是实现多频率和多星座数据处理能力。
