GNSS Simulator

Constellator™ Multi-constellation & Multi-frequency GNSS Simulator

  • Powerful & High Fidelity
  • Configurable for advanced simulation
  • Easy to setup & use
  • Built to evolve with your needs

The flagship GNSS Simulator

When we think about the expansion of GNSS constellations and satellite-based augmentations systems, we know it has provided more options as well as more complexity than ever before.


More constellations, more frequencies, more modulations, and more codes are making the development of tomorrow’s receiver tests a very demanding task.


Whether you need a GPS simulator or a fully-featured GNSS Simulator, Constellator™ is the perfect fit for your testbed environment.


Constellator™ singularity lies in the alliance of SDR (Software Defined Radio), a state-of-the-art RF Analog front-end and simulation models that got refined over 20 years.


Top-end processing performance and superior RF quality are now met into a COTS appliance with utmost flexibility in simulation control.

Final Assembly Line

receivers & antennas testing

With 240 channels, RTGS4-12 and RTGS4-14 offers more configuration options for validation process.


It allows high-fidelity simulation with many satellites in view even in multi-frequency and multi-constellation mode.

It also shines in multipath scenario.


Testing GPS/GNSS integration within a vehicle

Top of its class, RTGS4-24 offers 660 L1 C/A equivalent signals and the full power of Constellator™ for high-end R&D.


RTGS4-24 tackles the most challenging scenarios, from multi-constellation & multifrequency whether in space and to advanced multipath on the ground.


Testing new receiver and navigation systems in R&D


up to 1,000 Hz & Zero effective latency


Constellator™ allows hardware-in-the-loop GNSS simulation at high-fidelity, even under very-high dynamics, with zero effective latency.


It allows safe and controlled tests while saving time, budget, and effort.
