How do you test PNT?

Join us on the journey to testing infinity!

Positioning, navigation, and timing (PNT) represent a complex realm influenced by countless variables, where precision is paramount. Testing in real-world conditions presents challenges due to the uncontrollable nature of scenarios and their variables. Key issues include traceability, repeatability, and cost. Simulation emerges as a solution, offering controlled testing of infinite scenarios. To ensure authenticity and precision in results, we focus on avoiding unwanted test artifacts and providing user control over test conditions. With Spirent's sophisticated simulation tools, PNT testing embraces the infinite, ensuring every detail matters. Watch our latest video and discover more about the Spirent GSS7000 multi-frequency, multi-GNSS simulation system. Designed for robust PNT testing, the GSS7000 supports a wide range of automotive use cases and an infinite number of variables. This includes simulating the full range of open service GNSS signals and SBAS and correction messages (including RTK and PPP). Let's begin the journey to testing infinity!

How do you create a realistic GNSS test environment?

GNSS testing aims to assess device performance under varied real-world circumstances, emphasizing the importance of realistic testing for PNT systems. Lab-based simulation offers a solution to the challenges of repeatability and error tracing in real-world testing, providing enhanced realism and fidelity, while reducing expensive and time-consuming field testing. While fully replicating the real world in the lab is impractical, accurate modeling of vital elements such as transmitters, receivers, and vehicle dynamics significantly improves simulation environments. Critical considerations for creating a realistic yet deterministic test environment include faithful replication of GNSS signals, tight software-hardware coupling, and mirroring real-world characteristics. Realistic lab testing accelerates time to market, reduces test costs, mitigates deployment risks, and enhances safety. Our eBook, Test Infinity, guides you in creating realistic GNSS test environments, empowering you to master PNT integration and validation.

Generating better results through high-quality lab testing: Realism in GNSS testing

Let's take a closer look at the advantages of establishing a more realistic test environment for PNT engineers across various user communities. This webinar from Inside GNSS discusses crucial elements of GNSS test environments, including transmitters, propagation channels, antennas, receivers, vehicles, and sensor integrations. And don't miss a modeling case study from QuNav, which further illustrates how simulation and modeling of system parameters impact overall system performance, particularly in GNSS/INS integration for automotive applications. This expert panel features Andrey Soloviev from QuNav, with Guy Buesnel and Romain Zimmermann Spirent. Watch on-demand and learn how to get better results through high-quality lab testing.
