Keysight Technologies Inc. Unveils PNT Xe: A Revolutionary GNSS Simulation Platform

On November 11, 2025, Keysight Technologies Inc., through its subsidiary Spirent Communications, announced the launch of PNT Xe, an innovative global navigation satellite system (GNSS) simulation platform. This groundbreaking tool is designed to enhance high-performance GNSS testing across the development lifecycle, making it more accessible and economical for a wide range of users—from early prototypes to production line testing.

The introduction of PNT Xe aims to remove existing barriers in Positioning, Navigation, and Timing (PNT) testing. Spirent's Divisional CEO, Peter Terry-Brown, emphasized that PNT Xe democratizes access to high-quality simulation capabilities, allowing engineers to conduct reliable testing without the need for inconsistent simulators or reliance on live signals. This advancement is significant for both commercial and military applications, ensuring that developers can validate GNSS performance quickly and accurately.

PNT Xe is engineered to support multiple stages of development, from initial prototype testing to rigorous performance evaluations on production lines. The platform's purpose-designed hardware facilitates dependable and realistic testing, which is critical as PNT technologies continue to evolve at a rapid pace.

Rob VanBrunt, CEO of Spirent Federal Systems, remarked on the platform's transformative potential for defense customers, highlighting its ease of use, which allows software engineers to test minor code changes directly at their desks. This capability accelerates the deployment of new PNT technologies, enabling agile continuous integration.

PNT Xe boasts a compact footprint that can be easily rack or desk mounted. Its intuitive interface simplifies scenario creation, significantly reducing both time and costs associated with testing. The platform is designed for seamless transitions between lab and field environments, demonstrating resilience against temperature and vibration variances while maintaining performance integrity.

The platform supports all GNSS constellations and frequencies, ensuring it meets a diverse array of project requirements. With access to AES M-Code and a removable system disk, PNT Xe is compatible with secure testing environments, making it a versatile solution for various applications ranging from low-altitude drone operations to defense systems and autonomous vehicles.

One of the standout features of PNT Xe is its capability to facilitate unclassified military signal testing using AES M-Code. This advancement allows authorized users to conduct testing without the constraints of secure labs, thus broadening the scope for military applications.

As positioning and timing technologies become essential for advancements in fields such as 6G communications, defense systems, and autonomous vehicles, the need for high-performance simulation is paramount. Marie Hattar, Chief Marketing Officer of Keysight Technologies, underscored this point, stating that PNT Xe equips innovators with the tools necessary to validate the performance, reliability, and resilience of their systems at every stage of development.

Built on Spirent's 40 years of expertise in signal generation architecture, PNT Xe is set to revolutionize the landscape of GNSS simulation. By providing a powerful yet accessible platform for testing, Keysight Technologies Inc. is paving the way for a new generation of connected devices and technologies. As the industry continues to evolve, PNT Xe stands out as a critical asset for developers, integrators, and engineers across numerous sectors.
