Key facts
For production testing, RX characterization and testing for GNSS threats
Vector signal generators from Rohde & Schwarz have several GNSS options available that can turn them into reliable, full-featured GNSS signal sources. Their advanced simulation capabilities enable the configuration of realistic, complex yet repeatable GNSS scenarios that can be run under controlled conditions. This includes realistic modeling of GNSS orbits, signal propagation effects and system errors as well as realistic modeling of the user environment.
Realistic GNSS scenarios
GNSS simulators from Rohde & Schwarz have highly realistic scenarios that take into account all important signal propagation, user environment and system characteristics such as:
RAIM testing.
Pseudo-range ramps can be used for testing receiver autonomous integrity monitoring (RAIM) features.
A case for GNSS simulators
Signal generators have major advantages in GNSS simulations. When applying live signals, test conditions can change permanently and unpredictably, making repeatable testing impossible. GNSS testing solutions from Rohde & Schwarz provide well-defined, controlled conditions for GNSS simulations. The scenarios are fully customizable and repeatable, allowing a test scenario to be replayed as often as needed, while producing the same signals with the same characteristics.
GNSS simulation with the R&S®SMW200A.
The R&S®SMW200A can generate GNSS signals and other signals simultaneously, making it ideal for advanced GNSS testing .
Testing for coexistence signals, jamming and spoofing
GNSS simulators from Rohde & Schwarz can have an internal noise generator to add well-defined noise or even a CW interferer to GNSS signals. GNSS signals can also be combined with other digital standards, such as LTE or even pulsed signals, enabling the setup of complex coexistence scenarios to test receiver resilience against unwanted interference or jamming attacks.

Integrated simulation software
GNSS simulators from Rohde & Schwarz come with integrated simulation software that allows
simulation configuration, monitoring and interactive control on a
large touchscreen. Simulation data can be logged for postprocessing. No external
PC is required to configure scenarios. Scenario generation can be fully automated with extensive remote control capabilities.
User friendly interface.
