Key facts

  • Multi-constellation, multi-frequency and multi-antenna scenarios
  • GNSS + interference in one box
  • GPS, GLONASS, BeiDou, Galileo, NavIC/IRNSS, SBAS and QZSS with up to 612 channels
  • Realistic modeling of GNSS errors 
  • Moving scenarios and integration in HiL/ViL environments

Realistic and repeatable GNSS scenarios

For production testing, RX characterization and testing against GNSS threats

Vector signal generators from Rohde & Schwarz can be equipped with a multitude of GNSS options, turning the instruments into reliable, full-featured GNSS signal sources. Their advanced simulation capabilities enable configuration of realistic and 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.

Features & benefits

Test like it's real

Realistic GNSS scenarios

GNSS simulators from Rohde & Schwarz provide highly realistic scenarios, taking into account all important signal propagation, user environment and system characteristics such as:

  • Orbit and clock errors
  • Tropospheric and ionospheric effects
  • Signal obscuration and multipath
  • Antenna gain and phase patterns
  • Vehicle motion and vehicle attitude
  • Pseudo-range steps and ramps for RAIM testing

Simulation vs. live testing

A case for GNSS simulators

Using signal generators for GNSS simulation has some major advantages. When applying live signals, test conditions change permanently and unpredictably, making repeatable testing impossible. GNSS test solution from Rohde & Schwarz ensure that GNSS simulations are performed under well-defined, controlled conditions. They offer fully customizable and repeatable scenarios, so that a test scenario can be replayed as often as needed and produce the same signals with the same characteristics.

With its ability to generate GNSS signals and other signals simultaneously, the R&S®SMW200A is the ideal tool for advanced GNSS test tasks.

GNSS & interference in one box

Testing against coexistence signals, jamming and spoofing

GNSS simulators from Rohde & Schwarz can be equipped with an internal noise generator to add well-defined noise or even a CW interferer to the GNSS signals. GNSS signals can also be combined with other digital standards such as LTE or even with pulsed signals. This enables the setup of complex coexistence scenarios testing the receiver’s resilience against unwanted interference or jamming attacks.

With its ability to generate GNSS signals and other signals at the same time, the R&S®SMW200A is ideal for advanced GNSS interference tests.

Scenario configuration made easy

Integrated simulation software

GNSS simulators from Rohde & Schwarz come with integrated simulation software that allows
simulation configuration, monitoring and interactive control on the instrument’s
large touchscreen. Simulation data can be logged for postprocessing. No external
PC is required to configure scenarios. Scenario generation can be fully automated using the instruments' extensive remote control capabilities.
