LEO Testing: Essential Simulation for GNSS and Alternative PNT Signals

A Free Webinar from Spirent

Whether you're integrating GNSS for in-orbit positioning (PNT for LEO) or developing next-gen LEO-based PNT services (PNT from LEO), the challenges are real — and the risks are high.

Join us to learn how high-fidelity GNSS simulation accelerates your development, reduces mission risk, and enables testing far beyond what flight campaigns or live-sky testing can offer.

What you’ll learn:

• The difference between "PNT for LEO" and "PNT from LEO"
• Justification for testing and need for GNSS simulator
• How simulation lets you test edge cases before launch
• Real-world use cases from mission teams already using Spirent’s tools

Who should attend:

Satellite engineers, mission validation leads, LEO PNT system designers, and anyone building or operating spacecraft that rely on—or deliver—position, navigation, and timing.
