  • Rohde & Schwarz and Greenerwave achieve fast antenna characterization

    Rohde & Schwarz and Greenerwave achieve fast antenna characterization

    A joint measurement trial, Rohde & Schwarz and Greenerwave have demonstrated that a near-field system can record a full radiation pattern of a 50 cm Ku band electronically steerable array for a SATCOM antenna in a half hour.

    The achieved results match simulation models within a decibel, making this approach a fast and reliable way to verify antenna performance.

    For manufacturers of SATCOM systems facing large chamber constraints, it offers a clear path to quicker, more cost-effective testing. 

    Electronically steerable array (ESA) antennas are becoming key components in modern SATCOM systems. Accurate knowledge of their radiation pattern is required for reliable operation in LEO, MEO and GEO orbits. However, conventional far‑field testing demands chambers that are often larger than practical for Ku or Ka band antennas, especially when the aperture of the Antenna Under Test (AUT) reaches half a meter or more.

    Compact Antenna Test Ranges (CATR), on the other hand, are still relatively large for these AUTs and require time-consuming dual-axis positioning of AUT to map the radiation pattern.

    Rohde & Schwarz and Greenerwave have reached a breakthrough in ESA antenna testing in a joint measurement trial, achieving highly accurate radiation pattern characterization in the near field, significantly reducing measurement time. Greenerwave’s innovative SATCOM user terminals are based on reconfigurable intelligent surfaces (RIS), allowing the company to design electronically steerable antennas that deliver high-performance connectivity while reducing energy consumption and reliance on semiconductors compared with conventional solutions.

    For the joint measurement campaign, Rohde & Schwarz provided its R&S TS8991 over‑the‑air and antenna measurement system, equipped with a conical cut positioner, and its R&S ZNA vector network analyzer. Together, they evaluated Greenerwave’s passive single‑aperture ESA that uses RIS technology for beamforming. The antenna under test (AUT) features a 50 x 50 cm aperture and is designed for low power consumption and easy integration. 

    The measurement covered an extended upper hemisphere down to a polar angle of 120 degrees, using a one-degree step size. Ten Ku band frequencies were recorded in a total of 32 minutes, thanks to the system’s hardware trigger function. Data was processed using the R&S AMS32 antenna measurement software, which applied a FIAFTA near-field-to-far-field transformation algorithm. 

    Comparison with the original simulation based on a numerical twin model and with results from Greenerwave’s CATR setup showed peak gain or directivity variations of max. 1 dB and typically 0.3 dB, validating the accuracy of the near-field solution. Export options allow users to continue analysis in tools such as CST Microwave Studio or MATLAB.

    The trial shows that even large SATCOM antennas can be characterized quickly and accurately with the R&S TS8991 antenna test system from Rohde & Schwarz in a near-field setup, providing a practical alternative to large-sized far-field chambers or CATRs. 

    According to Rohde & Schwarz, the system setup can be used by other SATCOM makers testing broadband, IoT or back haul antennas for applications requiring flexible beam control and high data rates. The setup can be integrated more easily into research lab environments, and it shortens test cycles, reducing overall development cost.

    Chimera Land is a 3D laser velocity sensor (LVS) designed to solve the primary challenge for underground mining: maintaining precise vehicle positioning in deep,
    dark and unmapped environments where GPS cannot reach. When fused with an Advanced Navigation inertial navigation system (INS), Chimera Land allows underground vehicles to maintain stable navigation over extended distances and time. Instead of needing to query an external beacon or satellite for its location, the sensor uses specialized lasers to measure a vehicle’s ground-relative 3D velocity with high accuracy. By feeding this precise data into the vehicle’s INS, the sensor eliminates the drift that typically comes with standalone INS. Using AdNav Intelligence, the result is a resilient, high-performance, infrastructure-light positioning solution that excels in the highdust, zero-light conditions typical of underground mines.

  • Rohde & Schwarz enables Xona Pulsar signal simulation for next-generation navigation devices

    Rohde & Schwarz enables Xona Pulsar signal simulation for next-generation navigation devices

    New test capability supports device manufacturers preparing for Xona’s commercial LEO navigation constellation.

    Rohde & Schwarz is providing signal simulation capabilities supporting Pulsar, the next-generation satellite navigation service developed by Xona.

    The new functionality enables manufacturers to test Pulsar capabilities in production settings using Rohde & Schwarz signal generators, providing an accessible pathway for validating and scaling devices with next-generation positioning, navigation and timing (PNT).

  • CAST Navigation delivers advanced GNSS simulation for complex environments

    CAST Navigation delivers advanced GNSS simulation for complex environments

    Testing GNSS receiver systems in real-world conditions is limited by unpredictability, legal restrictions, and the inability to replicate scenarios. CAST Navigation addresses this challenge with advanced simulation technology that creates controlled, repeatable satellite signal environments.

    When testing a GNSS, comprehensive testing usually isn’t possible when relying on live satellite signals, according to CAST Navigation. In a live environment, engineers can’t determine the exact cause of errors, which can slow development and increase risk, so it’s impossible to establish controlled conditions suitable for experimentation and isolate specific variables without using a controlled signal environment.

    A valid experiment requires repetition of identical scenarios because it enables engineers to validate assumptions, debug faults and compare performance. Without this consistent verification, it’s impossible to put confidence in a satellite system, CAST Navigation said.

    Also, certain GNSS conditions can’t be put into practice in the real world for testing purposes. For example, spoofing or jamming satellite signals is usually illegal because such activities could cause interference or harm in other systems. Also, environmental effects like atmospheric interference or terrain obstruction can’t be easily configured or isolated in a live testing scenario.

    Improving reliable testing

    A controlled simulation environment that can generate repeatable GNSS conditions enables engineers to conduct reliable testing and validation. CAST Navigationprovides such a highly realistic and reliable simulated satellite signal environment, enabling organizations to conduct rigorous testing of guidance systems and positioning technologies. By creating artificial signals that can be precisely repeated as many times as necessary, engineers can get the data they need without the difficulties and restrictions of operating in a real-world environment.

    Multi-constellation frequencies available

    At the core of this technology from CAST Navigation is the ability to generate multi-constellation GNSS signals across multiple frequencies, such as GPS, GLONASS and BeiDou. These systems are highly adaptable to all kinds of experimental conditions. They support simultaneous simulation of multiple satellite systems at once, allowing engineers to account for variables like terrestrial movement and space-based trajectories.

    Using advanced motion modeling, engineers can use CAST’s system to simulate position, orientation and complex motion patterns in real time. But CAST Navigation technology isn’t just modeling satellite movement. It’s also modeling the environment the satellites are operating in, with variables such as atmospheric interference (such as ionospheric delay) fully integrated into the testing environment.

    Engineers can test their production systems in both ideal and adverse environments, such as one where satellite signals are being jammed. This makes CAST Navigation systems suitable for both military and commercial applications, particularly when engineers are trying to design resilient and flexible GNSS systems.

    CAST Navigation offers full-service support.

    Spirent’s SimXTRACT provides real-world PNT testing with signals from the field

    Spirent Communications, now part of Keysight Technologies, has launched SimXTRACT, a GNSS test tool that bridges the gap between field and laboratory.

    SimXTRACT enables signals captured in field environments to be comprehensively decomposed into individual, discrete signals and applied to lab simulation for realism at every stage of the development test cycle.

    “By combining real-world insights with lab-based control and repeatability, our customers will no longer have to compromise on how they test in this fast-moving technology area,” said Peter Terry-Brown, divisional CEO of Spirent’s Positioning business. “SimXTRACT ensures customers get the best of both worlds, with enhanced realism delivering more accurate results, quicker issue resolution, and faster time to market.”

    Developers usually rely on either RF record-and-playback or lab simulation for testing and validation of PNT systems and devices. While both methods play important roles in product development, neither is able to combine the richness of the real world with the control needed for tasks such as research and development, receiver integration, or regression testing.

    The introduction of SimXTRACT brings the advantages of both field and lab test methods together by taking real signals captured in field environments and accurately breaking them apart to create realistic simulator drive data for use in Spirent simulators.

    Using signals and scenarios captured in the field by Spirent record-and-playback devices, SimXTRACT performs complex signal decomposition, breaking down each received signal into discrete line-of-sight and multipath ray paths, along with metadata such as Doppler offset, code error, power level, and angle of arrival (AoA).

    This decomposed environment is then automatically converted into fully controllable simulation scenarios for Spirent GNSS simulators, reducing time spent in the field, cutting the cost and complexity of scenario capture and generation, and enabling repeatable, high-fidelity testing.

    Combined with the option for developers to analyze and understand signal recordings, as well as search for and recreate specific conditions in order to focus testing, SimXTRACT will help accelerate development workflows for sectors that include automotive, chipset, consumer devices, defense, critical infrastructure and more.

    “In today’s high-precision PNT ecosystem, SimXTRACT redefines how you can develop, test and debug PNT-enabled systems,” said Terry-Brown. “You can now bring the real-world environment into every stage of your product realization process, saving you time and money, while also improving product quality.”

  • Safran acquires Syntony to strengthen position in resilient PNT market

    Safran Electronics & Defense has acquired Syntony GNSS, a simulator and receiver company founded in 2015 in Toulouse, France. The acquisition is intended to strengthen Safron’s resilient PNT innovations.

    In 2023, Safran acquired Orolia, also for its GNSS and PNT expertise.

    Under the agreement, signed Feb. 13, Safran will take 100% of Syntony’s share capital, subject to customary regulatory approvals. Financial terms were not disclosed.

    A European leader in GNSS solutions for underground environments, Syntony has developed unique expertise to ensure reliable positioning in contexts where satellite signals are unavailable.

    Syntony’s technology addresses a major challenge of satellite navigation systems: the vulnerability of GNSS signals to physical obstacles, jamming and interference. To tackle this, Syntony has developed several critical technologies, including:

    • Controlled reception pattern antennas (CRPAs) that make GNSS receivers less sensitive to jamming and spoofing — essential for flight safety and the protection of sensitive infrastructure.
    • Software-defined radio (SDR), a digital radio that can change function (switching from FM to Wi-Fi or GPS) through a simple software update without changing hardware, allowing it to adapt to threats or to changes in received or transmitted signals. It offers compactness and scalability, particularly suited to embedded systems and the requirements of modern operational environments.

    In addition, Syntony develops GNSS receivers for next-generation satellites, particularly for low Earth orbit (LEO) constellations, further strengthening Safran Electronics & Defense’s offering in the space-based PNT and New Space sectors.

    Syntony employs nearly 70 people across Toulouse and Paris.

    For Safran Electronics & Defense, this acquisition makes it possible to offer more comprehensive equipment that is also more compact and energy-efficient, while remaining adaptable to the constant evolution of signals. These gains in weight and power consumption are essential for future civilian and military platforms (drones and counter-drone systems, missiles, aircraft and low-orbit satellites).

  • Spirent launches PNT Xe to expand GNSS testing access

    Spirent launches PNT Xe to expand GNSS testing access

    Spirent Communications, now part of Keysight Technologies, announced PNT Xe, a GNSS simulation platform designed to expand high-performance GNSS testing across the development lifecycle. The platform aims to reduce barriers to positioning, navigation and timing testing by offering simulation capabilities in what the company describes as an economical, multipurpose platform.

    The company said PNT Xe addresses challenges manufacturers face in validating GNSS performance during accelerated development schedules. The platform’s hardware supports testing from early prototypes through production line verification for commercial and military applications.

He said PNT Xe makes the company’s simulation technology available for workstations, engineers and project phases.

    Terry-Brown said the platform allows developers, integrators, design verification teams and production line testers to use consistent test methodology without compromising results validity. Many leading GNSS chipsets and modules are developed using Spirent’s simulators, he said.

    The compact PNT Xe can be rack or desk mounted and features an interface designed to accelerate scenario creation. The platform can operate in lab or field environments and withstand variations in temperature and vibration while maintaining performance, according to the company. It supports all GNSS constellations and frequencies and includes AES M-Code access and a removable system disk for secure testing environments.

    Rob VanBrunt, CEO of Spirent Federal Systems, called PNT Xe “a game-changer for defense customers.” He said the platform’s ease of use will help deploy new PNT technology faster, allowing software engineers to test code changes at their desks. Authorized GPS M-Code users can conduct unclassified military signal testing using AES M-Code without relying solely on secure labs, he said.

    Marie Hattar, chief marketing officer at Keysight Technologies, said accurate, high-performance simulation becomes critical as positioning and timing technologies become foundational to 6G, defense systems and autonomous vehicles. PNT Xe makes that capability available to more innovators to validate performance, reliability and resilience at every development stage, she said.

    Built on Spirent’s 40 years of expertise, PNT Xe is designed for development and production environments including low-altitude drones, vehicles, space applications, automotive, defense, and consumer devices.

  • Simulating signal threats with Safran Electronics & Defense

    Simulating signal threats with Safran Electronics & Defense

    In universities across the world, theory lays the foundation, but in the field, realism builds true expertise.  

    For students studying GNSS engineering, textbooks and simulations alone are no longer enough. Tomorrow’s engineers need to use the same applications and work with the same complex environments that professionals face in the real world. This means using tools that generate actual RF signals, not just software abstractions — tools that recreate urban canyons, interference, jamming, spoofing and satellite dynamics with precision. 

    Safran has established the Minerva Academic Partnership Program, an initiative that brings its Skydel GNSS Simulation Engine to qualified educational institutions worldwide. 

    A Modern, Software-Defined Approach to GNSS Simulation

    At the heart of this initiative is the Skydel simulation engine, a software-defined GNSS simulator. Built to leverage commercially available off-the-shelf (COTS) hardware, Skydel eliminates the need for proprietary hardware. It delivers the full spectrum of satellite constellations — as well as LEO ones — and frequency bands. By integrating Skydel in their projects, researchers now have the tools to pursue ambitious ideas with confidence, such as:

    ■ Designing and testing custom signals or constellations not yet in existence

    ■ Simulating real-world scenarios that can include both environmental and man-made interference

    ■ Integrating and testing additional sensors and platforms through open-source plug-ins and hardware-in-the-loop setups

    ■ Conducting rigorous resiliency testing against jamming and spoofing in a controlled, repeatable environment without real-world risk

    ■ Building their own simulator with existing hardware components around Skydel

    Empowering the Next Generation of PNT Innovators

    Through the Minerva program, Safran provides full-feature Skydel licenses for faculty and student use, creating an environment where learning and innovation thrive. This initiative not only eliminates the barrier to entry but also fosters collaboration between academia and industry –— fueling a new wave of GNSS advancements.

    A Global Initiative

    Today, Minerva includes more than 80 member institutions and boasts a growing portfolio of peer-reviewed publications and conference presentations.

    “This momentum highlights the real-world impact of the program and its role in driving local research excellence and fostering a vibrant, collaborative international GNSS community,” said Pierre-Marie Leveel, program director of PNT simulation at Safran Electronics & Defense. “Safran Electronics & Defense’s Minerva program is more than just a software — it’s a mission to democratize GNSS simulation and nurture the next generation of PNT researchers. As innovation becomes more critical to national sovereignty, transportation, and space exploration, empowering students and researchers has never been more vital.” 

    Elevating GNSS Simulation

    The evolution of Safran Electronics & Defense’s GNSS simulators — across both software and hardware — has been shaped by the growing demands of users and the broader market.

    “The demand for multi-vehicle and multi-antenna scenarios has never been higher, and the same can be said for interference simulation,” said Pierre-Marie Le Veel, program director of PNT Simulation at Safran Electronics & Defense.

    To address these challenges, Safran’s GSG-7 and GSG-8 Gen2 simulators are engineered to handle a range of applications, from basic to advanced GNSS jamming and spoofing resiliency testing.

    The GSG-7 simulator is designed for location-aware applications and systems that depend on navigation or timing. With high-end performance — featuring a 1,000 Hz simulation iteration rate, high dynamics, real-time synchronization, and all-in-view satellite signal simulation — the GSG-7 is well-suited for development and integration projects that demand high performance and extensive constellation licensing. It supports multi-constellation and multi-frequency GNSS simulations and can be configured to operate with all current and upcoming GNSS signals.

    Meanwhile, the GSG-8 Gen2 is the latest iteration of Safran’s GSG-8 model, offering flexible simulation capabilities for any device that relies on GNSS signals. Built on Safran’s Skydel-based simulation platform, the GSG-8 Gen2 helps users model scenarios.

    Powered by high-end GPUs, the GSG-8 Gen2 offers reliable and precise GNSS signal testing. It can simulate thousands of signals, run multiple instances at once, and introduce jamming and spoofing to evaluate system resilience. The turnkey system features a redesigned chassis for greater connectivity, including six front-facing, high-quality RF outputs, a combined output covering the full GNSS bandwidth, and the same high-end simulation iteration rate as the GSG-7. This allows users to quickly get up and running with complex simulation requirements.

    “The market is also demanding realism,” Le Veel said.

    All Safran simulators are powered by the Skydel Simulation Engine, which is updated quarterly. Each release introduces new features, signals, and enhancements, enabling more authentic simulations and offering the flexibility to create virtually any GNSS testing scenario.

    Staying Ahead of Market Changes and Signal Threats

    The recent increase in signal interference threats has driven the demand for enhanced positioning, navigation and timing (PNT) resilience, leading to the broader use of both conducted and over-the-air (OTA) testing. The anticipated deregulation of controlled reception pattern antenna (CRPA) technology also is expected to open the door for civilian markets to perform testing.

    “Throughout the past few years, Safran Electronics & Defense has massively revamped our approach to the Wavefront platform and now offers the GSG-Wavefront for those testing CRPA antennas against jamming and spoofing threats,” Veel said.

    The ability to safeguard GNSS networks from jamming and spoofing attacks has never been more vital. Achieving this level of resilience calls for a GNSS simulator that can generate dedicated RF signals for evaluating the effectiveness of CRPA architectures.

    Safran’s GSG-Wavefront, featuring a shared local oscillator (LO) design, stands out as a field-proven, off-the-shelf solution for CRPA receiver testing. It has a customizable platform that offers upgradable options powered by Skydel — the company’s GNSS simulation engine.

    Le Veel added, “We are working hard to keep up with demand in both the defense and civilian markets.”
    In addition, Le Veel noted that Safran’s GSG-Anechoic is attracting attention from users who work with anechoic chambers, thanks to its multiple, independent RF outputs, automatic antenna mapping, and built-in calibration features for delay and power loss.

    Safran Electronics & Defense supports a wide array of users in both the civilian and defense sectors, spanning aerospace, critical infrastructure and transportation. In recent years, however, the company has seen its fastest growth in the New Space market. Safran’s simulators are used in a range of cutting-edge applications, including satellite navigation, low-Earth orbit (LEO) constellations, and rocket launch and landing systems.

    “We are proud that the flexible tools and features we have included in Skydel are being used in these incredibly robust applications,” La Veel said.

    A challenge for most GNSS simulation suppliers is ensuring compatibility and coherence with a wide range of GNSS receivers. La Veel shared that Safran Electronics & Defense is in a unique position, as it also designs and manufactures its own receivers, such as the newly released Skylight.

    “Additional challenges can arise when developing new signals or constellations, such as the newest LEO ones, said La Veel. “Our close partnerships with both Xona Space Systems and TrustPoint have allowed us to overcome these challenges.”

    A single GSG-8 Gen2 simulator from Safran Electronics & Defense can generate more than 2,000 signals without the need for additional hardware. This capability is essential when modeling legacy signals, multipath effects, jamming and spoofing scenarios, or even LEO-constellations.

    Safran simulators support all legacy signals, including GPS, Galileo, BeiDou, GLONASS, NavIC, QZSS and SBAS, across all bands and security features such as M-code, PRS and Galileo OSNMA. The systems also offer compatibility with emerging LEO constellations, including Xona’s PULSAR X1 and X5, as well as TrustPoint. Custom Signals and Custom Constellation features offer users the flexibility to create entirely new signals and satellite constellations, or to modify existing configurations.

    “It is de rigueur these days for companies to claim or incorporate AI into their solutions. In addition to using AI for tropospheric modeling based on real-world data, Safran Electronics & Defense has also taken a different approach to using AI in GNSS simulation,” Le Veel said.

    He added that the company’s upcoming demonstration at ION GNSS+ 2025 will reveal Skydel AI, a new tool designed to make scenario creation and parameter setting as simple as writing an email. “The amount of people who can easily now test their prototypes, products or systems will dramatically increase as the steep curve to learn GNSS simulation is flattened.”
