Multi-frequency and multi-antenna GNSS simulator R&S SMW200A from Rohde & Schwarz

Rohde & Schwarz’s SMW200A simulator generates realistic test scenarios for all GNSS standards

  • The R&S SMW200A GNSS simulator complemens Rohde & Schwarz’s range of satellite navigation simulators.
  • This instrument, which integrates up to four RF outputs, can simulate GNSS signals simultaneously for testing multi-frequency and multi-antenna systems.
  • This GNSS simulator is equipped with an internal noise generator, and can generate interference scenarios with several disturbances.

GNSS (Global Navigation Satellite System) receivers are capable of processing signals from various satellite navigation systems such as GPS, Glonass, Galileo or BeiDou operating in various frequency bands and operating multiple antennas to improve positioning accuracy.

The level of accuracy can be further increased with Differential GNSS (DGNSS) techniques. These are used in applications such as autonomous driving of vehicles, and during the landing phases of aircraft.

The R&S SMW200A GNSS R&S Simulator is a test solution that aims to simplify the generation of realistic and complex test scenarios. For testing of multi-frequency and multi-antenna systems, 72 GNSS channels, which can be allocated over four RF outputs, are now available for testing.

This GNSS simulator can generate QZSS and SBAS signals, as well as GPS, Glonass, Galileo and BeiDou signals. This makes it possible to check the relative position of receivers under real conditions.

According to Rohde&Schwarz, the R&S SMW200A simulator is the first and only high-end GNSS simulator on the market with an internal noise generator, and capable of generating complex interference scenarios with multiple disturbances. All signals (GNSS, noise and interference) are delivered directly from the unit. No additional signal source is therefore required for external interference generation.

GNSS tests and scenarios are configured without the need for an external PC via the integrated graphical user interface.

The R&S SMW200A platform offers a variety of options and is intended to be scalable to meet future testing needs.
