Performance analysis for the Galileo HAS and related work in the DLR Galileo Competence Center

Satellite positioning, navigation and timing applications have become an integral part of our daily lives, resulting in a growing demand for standard and high-precision location services. High-precision GNSS solutions have been around for several years. They primarily serve the surveying, construction and agricultural industries with decimeter to centimeter positioning accuracy in real-time based on GNSS signal measurements and correction data. More recently, the Galileo High Accuracy Service (HAS) was declared operational and is expected to benefit various markets and applications, such as maritime transport, drones, autonomous driving and precision agriculture, among others.

A GNSS performance analysis and monitoring system is being developed in the DLR Galileo Competence Center. Various parameters are monitored to characterize the performance of the four satellite navigation systems. For example, code-based positioning solutions are estimated at various stations locations around the globe.

The Galileo HAS will also be integrated into this system. This contribution discusses the system development aspect for the integration of the HAS service. Performance parameters for all GNSS are then presented with a focus on the new Galileo HAS service. The data management aspect of this analysis, i.e. storage, management and retrieval of data is based on a relational database, open-source software and in-house developed software tools.

The HAS message content is analyzed for key performance indicators and other descriptive statistics. Furthermore, the positioning results at different IGS station locations will be presented in order to characterize and eventually monitor the positioning performance of this new Galileo service.
