SatGen, Racelogic’s GNSS simulation software, enables users to create real-world scenarios in just a matter of minutes. Through the software, data such as vehicle trajectory can be live-streamed directly from a simulator to a PC, creating those real-world driving scenarios. These can then be fed into a GNSS testing device such as a LabSat Real-Time, to create a GNSS signal that matches the simulated data.
Using both LabSat and SatGen has many advantages for AV testing departments. The GNSS signals that are generated are an exact match of the data outputted from a simulated vehicle, and can therefore be used in popular AV simulation environments, such as rFpro’s platforms. This enables engineers to virtually test in different weather and traffic conditions, as though they were in the real world.
There are many other benefits for autonomous vehicle engineers when using this approach to testing. Consistency is one, as when the vehicle is being validated in a driving simulator, a fair and representative test is assured each and every time, regardless of differing atmospheric and traffic conditions.
