    Syntony GNSS has partnered with Keysight Technologies, an RF testing solutions manufacturer, to advance GNSS testing and simulation capabilities.

    The collaboration centers on Keysight’s VXG advanced signal generator, which can generate thousands of simultaneous signals across all GNSS constellations and bands. It features time and phase synchronization for high fidelity and accuracy in simulation scenarios. This feature is particularly crucial for testing GNSS receivers under various conditions to ensure optimal performance in real-world scenarios.

    The Syntony GNSS Simulator Constellator can mimic the complex dynamics of GNSS signals, providing a platform for testing and validating GNSS receivers. When combined with Keysight’s VXG, it serves as a comprehensive testing solution for all GNSS signals and scenarios.

    The partnership aims to improve Controlled Reception Pattern Antenna (CRPA) testing. CRPA is pivotal in enhancing the resilience of GNSS receivers against interference and jamming to offer reliable operation even in adverse conditions. The combined solution from Syntony GNSS and Keysight offers a platform for testing CRPA systems to ensure they meet the stringent requirements of modern applications.

    Telecommunications, among other sectors, relies heavily on precise timing information, typically derived from GNSS signals. The threat of jamming attacks, which can disrupt GPS time synchronization, poses a significant risk, potentially crippling communications and other dependent systems. The testing solutions emerging from this partnership provide a toolset for infrastructure managers to evaluate and enhance the resilience of their systems against such threats.

    Orolia joins with Keysight on advanced 5G GNSS testing

    Integrated solutions address GNSS test requirements defined by 3GPP and major U.S. carriers

    Orolia and Keysight Technologies Inc. have joined forces to advance 5G services by addressing GNSS test requirements defined by 3GPP and major U.S. carriers.

    Working with Orolia allows Keysight to extend its 5G device test solution portfolio with advanced GNSS simulation capabilities. As a result, existing users of Keysight’s 5G device test solutions can easily address GNSS-related 3GPP protocol conformance and carrier acceptance test requirements by upgrading the software in Keysight’s E7515B UXM 5G Wireless Test Platform and combining it with Orolia’s GSG-8 simulator.

    The efforts of Keysight and Orolia will enable chipset and device makers to verify functionality to accurately position mobile phone users within a geographic area.

    “Working with Orolia has enabled Keysight to deliver GNSS-based LBS test solutions for 5G protocol conformance and carrier acceptance validation,” said Muthu Kumaran, general manager of Keysight’s device validation solutions business. “Keysight’s LBS solutions also support assisted GNSS test functionality, enabling users to comprehensively address 5G new radio conformance requirements mandated by both the Global Certification Forum (GCF) and PTCRB.”

    Accurate positioning is important in a wide range of sectors including healthcare, road and aerial transportation, entertainment and homeland security.

    Future applications, such as drones and autonomous vehicles, will depend on highly precise positioning services for reliable navigation and safe transportation of people and goods. Mobile operators use GNSS technologies and non-GNSS technologies, such as beamforming, angle-based positioning and round-trip time to deliver personalized services and support emergency calls.

    The GSG-8 simulator, powered by the Skydel Simulation Engine, offers high performance, flexibility and an easy-to-use software-defined platform to deliver superior jamming and spoofing options that can help ensure accurate, continuous operations for critical applications during interference or signal loss. Automated and scalable, the simulator supports GPS, Galileo GLONASS and BeiDou, with upgrade paths for future constellations.

    Keysight offers in-built positioning capabilities in the UXM 5G wireless test platform for non-GNSS positioning test requirements.

    “We are pleased to collaborate with Keysight on developing solutions that improve PNT testing for 5G communication networks and devices,” said Lisa Perdue, Orolia’s Simulation Product Line director. “Our GSG-8 simulator, powered by Orolia’s Skydel Simulation Engine, offers ultra-high performance and unmatched flexibility. The easy-to-use software-defined platform also delivers superior jamming and spoofing options that can help ensure accurate, continuous operations for critical applications during interference or signal loss.”
