As Positioning, Navigation and Timing (PNT) technologies continue to evolve, the demands placed on GNSS receivers are becoming increasingly complex. From autonomous vehicles and UAVs to aerospace, defense, telecommunications, and critical infrastructure, developers need to validate performance under an ever-growing range of operating conditions.
While field testing remains an essential part of system validation, it is often expensive, time-consuming, and difficult to reproduce. GNSS simulation provides a reliable and repeatable alternative, enabling engineering teams to test complex scenarios in a controlled laboratory environment and accelerate product development.
PNT emulators recreate realistic satellite signal environments, allowing developers to verify receiver performance before moving into field trials. By simulating real-world conditions, engineering teams can identify issues earlier, reduce development risks, and improve overall product quality.
Key benefits include:
Every GNSS application has different testing requirements. A receiver for an industrial IoT device has very different needs than an autonomous vehicle, an aircraft navigation system, or a defense application.
Rather than offering a one-size-fits-all solution, the Keysight PNT Emulator Hardware portfolio provides three dedicated performance levels, enabling engineering teams to choose the solution that best matches their application and technical requirements.
The Essential PNT Emulator Hardware (PNT Xe) is designed for development laboratories, production testing, and engineering teams looking for professional GNSS simulation in a compact and cost-effective solution.
Supporting multi-constellation and multi-frequency GNSS simulation with up to 128 channels, it is ideal for:
For more demanding engineering projects, the Expert PNT Emulator Hardware (GSS7000) provides enhanced capabilities for advanced development and validation.
Supporting up to 256 channels, the Expert platform includes features such as dual-antenna support, Hardware-in-the-Loop (HIL) integration, and advanced interference and spoofing simulation.
It is particularly suited for:
The Pro PNT Emulator Hardware (PNT X) is Keysight's highest-performance solution for the most demanding navigation applications.
Supporting up to 640 channels, the Pro platform is designed for advanced aerospace, defense, and high-end research environments requiring sophisticated multi-constellation simulations, embedded RF threat generation, inertial navigation integration, and CRPA testing.
Typical applications include:
Choosing the right PNT emulator depends on several factors, including application complexity, required GNSS constellations, channel count, dynamic test scenarios, and validation objectives.
