Software designed GNSS system emulator

This paper presents STELLA NGC: an open Software-Designed GNSS Simulator that provides the complete toolbox for GNSS testing. Indeed, this GNSS SDR is not only capable to simulate GNSS signals according to user-defined scenario, but it is also capable to Record & Replay “real GNSS signals” and to support performance evaluation ranging from low level signal processing to statistics on trajectories. Last but not least, STELLA NGC offers the possibility to add a broad variety of interference signals on top of the GNSS signals. This makes our solution a complete GNSS test and measurement platform. With this single platform, the user can access all generic and custom functions he needs, ensuring long-term evolution and optimizing return on investment.
