Software Designed GNSS system emulator

In this paper we present an open Software Designed GNSS Simulator that is not only capable to simulate GNSS signals according to user defined scenario but that also provides the capabilities to support record & replay “real signal” and to support performance evaluation ranging from low level signal processing to statistics on trajectories. Thanks to the software radio approach, the GNSS signal generator becomes a highly configurable tool that can support multiple test & measurement applications dedicated to GNSS community. With a single platform the user can access all generic and custom functions he needs ensuring long term evolution and optimized return on investment.
