Webinar: Understanding Latency for PNT Application Development
Watch this on-demand webinar to understand latency for PNT application development for PNT engineers in all key user communities.
You’ll learn from subject matter experts about:
How to overcome challenges in high-dynamic global navigation satellite system (GNSS) / inertial navigation system (INS) testing
The importance of sensor and mission realism in simulation
The fundamentals of modelling vehicle trajectories in a simulation environment, and how extrapolation plays a part in hardware-in-the-loop (HIL) environments
The difference between update rates and solution latency, and how these two concepts are connected

Hardware-in-the-loop (HIL) test environments offer a powerful and cost-effective option for developers looking to integrate multiple cooperative sensors, or developers who need to incorporate real-time external motion into their tests. Creating feedback loops from the device – or devices – under test enables dynamic and repeatable sensor fusion testing, as well as the introduction of elements such as human or autonomous steering interfaces.
However, creating a realistic HIL test environment that delivers repeatability, traceability, and reliability presents a number of challenges. Of these challenges, one that is often misunderstood is latency.
In this webinar, three experts discuss what latency means – both in a test environment and in real-world GNSS applications – and how it can be minimised. The webinar also discusses when latency is not important, as well as how and why test instruments can and/or do use extrapolation or interpolation to help to simulate a trajectory.
With representatives from the test and measurement industry, as well as from the PNT device development industry, the webinar offers a range of perspectives on how developers can incorporate more dynamic testing into their processes. In addition, there are a range of different views on how users can evaluate their test environment, evaluate their devices, and build in greater performance at every stage.
