A GLONASS constellation simulator provides an effective and efficient means of testing GLONASS receivers and the systems that rely on them by generating the same signals transmitted by GLONASS satellites, thus GLONASS receivers process the simulated signals in exactly the same way as signals from actual satellites. A GLONASS simulator provides control over the signals generated by the GLONASS constellation and over the global test environment all within a box, so that testing can be conducted in controlled laboratory conditions.

The Global Orbiting Navigation Satellite System (GLONASS) is operated by the Russian Space Agency. The GLONASS system is similar in basic concept to the U.S. controlled Global Positioning System (GPS) and the European Union’s Galileo system that is in development.

WHY USE A GLONASS SIMULATOR?

Testing with simulators is the widely accepted best practice for validating the performance of GLONASS receivers and systems in many different scenarios and operating conditions in a controlled laboratory environment. Simulators are used extensively in academia and industry, in virtually all GLONASS receiver manufacturing and major system integration and in many different application fields, including navigation, positioning, telecommunications, aviation, automotive, and space, for both civilian and military applications. Using simulators facilitates several stages of research and product development, including requirements analysis, design and development, integration, production, maintenance and support.

GLONASS SIMULATION BENEFITS

GLONASS simulators provide many benefits, including:

Control	Completeness	Reliability	Efficiency
Flexibility	Repeatability	Cost	Realism

GLONASS and GNSS Simulators provide the only effective means of testing new and future GNSS capabilities that are not yet supported by actual constellations, such as the GLONASS L2 and L3 signals and the Galileo system.

GLONASS TESTING

• The GSS8000 Multi-GNSS Constellation Simulator provides GPS/SBAS, GLONASS and Galileo signals. GPS configurations can also support QZSS and SBAS. Classified signals and various options are also available.
• The GSS6700 Multi-GNSS Simulation System offers multiple channels of GPS/SBAS, GLONASS and/or Galileo L1 signals.
• The GSS6300 Multi-GNSS Signal Generator provides a single channel of GPS/SBAS, GLONASS and/or Galileo L1 signals for production testing of commercial GNSS receivers.
