6 Ways the Design and Build of an RF Simulator Can Affect the Realism of GNSS testing_hero

The aim of GNSS testing is to understand how a GNSS-enabled device will perform in the infinite different circumstances of the real world. For this reason, realistic GNSS testing is crucial in the development and validation of positioning, navigation and timing systems that will perform in the hands of users. With the lack of repeatability and error tracing in real world testing, delivering realistic results depends on lab-based GNSS simulation and record & playback technologies.

Simulation and record & playback systems represent the state-of-the-art in lab-based testing for GNSS. With enhanced realism and the highest fidelity, the significant benefits of bridging the gap between lab and real-world testing can be realised. Foremost of these is to move more testing away from the field and into the cheaper, faster, and more scientific lab environment.

Learn how to create a realistic GNSS test environment in the lab to identify issues with your GNSS receiver. This eBook discusses considerations for realistic GNSS simulation and realistic RF record & playback solutions.

New tests conducted by Spirent in a live sky environment demonstrate that some commercial GPS receiver models can be compromised by spoofing devices at 10m, 50m and 100m distance.

Find out how Spirent used live sky signals alongside simulation to demonstrate how commercial GPS receivers are vulnerable to spoofing attacks.

GNSS test engineers can use simulators to create a realistic test environment – but how does the performance of the test equipment affect that aim?

Testing infinity: achieving realism in the lab

GNSS test engineers use simulators to create a realistic test environment – but what does that mean in practice, and which factors can affect test realism?

Testing infinity: achieving realism in the lab through optimum simulator performance

A holistic understanding of simulation components and their requirements for realism in GNSS lab-based testing is critical for choosing the right test platform in order to launch successful GNSS-enabled devices to market.

Choosing the right GNSS vehicle simulation and GNSS testing platform are keys to success for new GNSS launches.

Testing infinity: how to build a realistic GNSS test scenario

Find the GNSS simulator that's right for you.

It’s widely accepted that simulation is the primary tool for testing GNSS enabled equipment. However, selecting the right simulator is not simple. The first port of call should be to check the feature list – does the simulator offer the functionality you require? After this, though, you will need to establish whether the simulator performs as expected. Failure to do so could have catastrophic consequences for your product, and even your business.

This eBook unveils important performance characteristics to consider when choosing a GNSS simulator.

How to choose a GNSS simulator

Creating a realistic test environment is essential for understanding the receiver’s likely behaviour in real-world adversarial conditions.

Spoofing and other vulnerabilities testing is critical for GNSS-enabled technology. Find out how improved realism through Spirent's Standpoint can enhance your PNT testing.
