Problem We Solve

In order to properly test a GNSS receiver, or any device or system that relies on global navigation satellite signals, engineers need to simulate the same RF signals that are broadcasted by real satellites.

Test engineers may start with real-world, or “live-sky” tests to see how their new product or device will perform, but it is hard to replicate a test because the satellites are constantly moving. The atmospheric conditions also have variability, and it would be expensive and time-consuming to test a GNSS receiver in all the parts of the globe where it might be used.

Low-Cost GNSS Simulation is a helpful way to get around this because it allows you to create all the variables for a simulation right at your desk. You can then evaluate how your receiver device reacts to real RF signals, how accurate it is, and how it responds to different scenarios and different environments.

Why it is Important

It is estimated that 6.4 billion devices in the world rely on GNSS navigation signals – with increasing trends suggesting that this figure could rise to 9 billion devices by 2029. These types of devices range from a smartphone in someone’s pocket, to a complex flight navigation system inside an airplane. To be effective and ensure the safety of users, technology companies and system integrators need to develop methods of reliably and efficiently testing the GNSS receivers that they use in their systems and the possible scenarios that could occur.

How We Solve it

Orolia’s GSG 5/6 Series Simulators generate the same RF signals that are broadcasted by navigation satellites to test any device with a GPS receiver. The GSG 5/6 simulators can simulate all the major GNSS constellations that you may need for your testing, including GPS, GLONASS, GALILEO, BeiDOU, QZSS and SBAS – all through a single RF output.

The lightweight form factor means that you can conveniently place a GSG 5/6 simulator on your desk and or transport it easily to your office or testing lab.

The GSG 5/6 simulators can generate satellite signals that correspond to any position on or above the Earth. This gives you flexibility to create an unlimited number of test case scenarios that are relevant to your system and use-case.

Ease of Use:

  • Conveniently modify parameters of each simulation on the front panel. No need for superfluous serial connections and add-on utilities.
  • Designed so that even inexperienced operators can configure scenarios on the fly without the need for an external PC.

Why Choose Us

  • Powerful – Create an unlimited number of user-defined scenarios.
  • Flexible – The GSG 5/6 GNSS Simulators can be controlled either via an Ethernet Network Connection, USB, GPIB, or using a web user-interface where you can control the unit and the settings on the front panel.
  • Easy-To-Use – Predefined scenarios. Users can change the date, time, position, trajectory, number of satellites, satellite power levels and atmospheric models easily with the buttons on the front panel.
  • Powerful – Create an unlimited number of user-defined scenarios.
  • Lowest-Cost-Of-Ownership – GSG 5/6 GNSS Simulators are the most competitive on the market because they were designed to help test engineers quickly and efficiently test GNSS Receivers.
  • Free Add-On Software Included, StudioView™ – which helps you craft scenarios using Google Maps.


If you need to test dynamic conditions, for example, the movement of your receiver device over a given area, StudioView™ software gives you an easy way to define the trajectory of your receiver that is being tested.

StudioView™ software is a free add-on and comes with each GSG 5/6 Simulator. With StudioView™ you can easily create and edit scenario parameters. You can convert trajectories that you created in other programs from KMLs, KMZs and GPX files and turn them into NMEA data. Most importantly, the intuitive graphical user interface of StudioView™ allows you to use a Google Maps environment to configure your simulation scenarios.

Even though you can setup and run GNSS Simulations with the GSG 5/6 Simulators without the need of an external computer, StudioView™ allows the user even further control over the simulations and testing scenarios.
