GNSS Simulators - Overview

spirient gnss simulators overviewGNSS simulators from Spirent provide a superior alternative for testing compared to using actual GNSS signals in a live environment (live sky).

Some of the benefits of using a GNSS simulators are:

  • Control and repeatability;
  • Low project costs and shorter timescales;
  • Emulation of future signals before deployment (L2C, L5, L1C);
  • Flexibility to emulate a range of variables;
  • Completeness to test systems in all conditions;
  • Reliability with the "Truth" known for performance evaluation;
  • Efficiency to produce a range of tests in the laboratory; and
  • Real RF signals to test GNSS equipment core performance with support for hardware-in-the-loop testing.

Simulators are available to suite customer requirements, ranging from dual frequency, multiple constellations system of GSS9000 to single frequency multiple constellation standalone system of GSS6700 to a single channel single frequency system of GSS6300/GSS6300M.

GSS9000 | ULTIMATE flexibility


The Spirent GSS9000 Multi-Frequency, Multi-GNSS RF Constellation Simulator sets a new standard of excellence in GNSS RF Simulation for R&D and Performance Test.
The GSS9000 provides numerous benefits to the all those working in high-end GNSS technology and application development, including comprehensive and feature-rich simulation and full control of all aspects of the GNSS operating environment, inherent repeatability and the ability to apply systematic errors and incidents that are impossible to realise using actual satellite signals.
