Final Presentation of EL2-060 now available.

The market for GNSS signal simulators has increased rapidly in recent years. The ability to test receivers in an indoor environment with reliable data and precisely repeatable scenarios is highly desirable and widely used in industry today. The consortium working on this NAVISP Element 2 project GSGSE (GNSS Signal Generator Streaming Extension) is led by OHB Digital who have developed a GNSS signal Generator with a real time streaming capability of RF signals allowing for flexibility of a software-based simulation environment and real-time control capabilities such as switching on/off satellites, changing the simulated receiver trajectory, or changing environmental conditions to suit the desired testing scenario. The autonomous sector would benefit greatly from these real-time capabilities for their autonomous driving test cases.

More specifically, the GSGSE System is able to simulate satellite orbits and is able to model all error sources, delays and propagation effects. These include various models for satellite clocks, ionosphere and troposphere, multipath, signal power, antenna patterns and noise. Customized navigation message formats and contents can be used to simulate future GNSS signal features. In addition, it is possible to simulate jamming and spoofing attacks. Comprehensive data logging of all intermediate results is available for detailed analyses.

You can find the GSGSE product on the (OHB, IZT) websites. The product has received positive feedback from potential customers and a first unit of GSGSE has been already sold.

The project was part of NAVISP Element 2, which aims to maintain and improve the capabilities and competitiveness of the participating States' industry in the global market for satellite navigation and, more broadly, PNT technologies and services.
