CRPAs are a very useful antenna system for platforms that need to operate in environments where interference is commonly present. Uncover its power in testing. Home • Applications • CRPA Testing CRPA Testing Controlled Reception Pattern Antenna Testing What is a CRPA? • Testing a CRPA • Anechoic • Wavefront • Videos • Documents What is a CRPA? The acronym stands for Controlled Reception Pattern Antenna. CRPAs are designed to reduce the effects of RF interference or establish signals’ angle of arrival. Using multiple antenna elements, they minimize jamming signals, using null generation or null steering or maximize “truth” signals using beam forming or beam steering. CRPAs are a very useful antenna system for platforms that need to operate in environments where jamming and interference are commonly present. For this reason, CRPAs are becoming increasingly common, particularly in the Defense sector. They are an extremely effective anti-jam/spoof solution, because they adapt dynamically in response to jamming or spoofing signals. WHAT IS A CRPA What Makes a CRPA? CRPAs begin with some sort of multi-element antenna, but the real magic happens within the antenna electronics, where the RF then proceeds downstream to the GPS receiver. These items can be connected to each other in-line or in a single enclosure. Single-enclosure antennas are sometimes called “integrated CRPAs”. Fundamentally, they work the same way. Ways to Test a CRPA Testing a CRPA prior to fielding is critical − especially in applications like defense, where the stakes are high. There are several test methods for testing CRPA antennas. You should evaluate these methods, their costs and suitability for the use case to ensure that your needs are fully met. Record Replay Realistic, actual recorded data – not generated. Unable to make changes, limited test cases. Difficult to find a suitable recording environment. To record threats, you have to go where threats are. GNSS Simulator Lowest cost option due to advances in technology. Previously very expensive and complex equipment. Innovation now allows us to do some cool things. Flexibility to cover multiple test cases quickly. Anechoic Chamber A complete anechoic chamber system, including simulation equipment and an actual physical chamber. Very expensive, high effort. Physical limitations and building standards. Several potential unknowns Field Testing Bring device out in the field Staged environment and generated threats. Facilitates tangible conditions. Costly: must employ event staff, obtain threat licenses. Little control as attendee. TESTING A CRPA BroadSim Anechoic The anechoic method is the only way to test an entire system as-is, because it allows testing of both the antenna and the antenna electronics integrated in a single package without modification. Still, it requires that the chamber be an optimal size to accommodate the device or system under test, and you could be limited by the antenna setup in the chamber. Skydel auto-calibrates the system, maps the antennas, and is designed to streamline chamber setup and reduce the multiplication of hardware systems. Interference can be integrated with Skydel software or an external generator. VIEW PRODUCT ANECHOIC BroadSim Wavefront The wavefront method brings all signals for each antenna element to the antenna electronics via cables. It prioritizes the ability to have dynamic trajectories for the receiver and for the interference transmitter, which lets you do a great deal of testing. You can essentially model any scenario with an unlimited number of interferences. A wavefront system is packaged lab-ready. Although it doesn't test the antenna, the important part to test is the antenna electronics, making it a good solution for testing CRPAs. It is the lowest-cost option considering all the variables. Be aware of any limitations such as signals, jammers and spoofers, and scalability for future needs. Skydel Wavefront is scalable from two to sixteen elements, is phase coherent, performs real-time automated phase synchronization, and has built-in jamming and spoofing.

As GNSS vulnerabilities rapidly evolve, integrating LEO PNT into your solution is critical. Discover success by testing and integrating a plan from the start. Home • Applications • LEO PNT LEO PNT Low Earth Orbit Positioning Navigation, and Timing. What is LEO PNT? • Why LEO PNT? • How is LEO PNT being implemented? • LEO PNT Resources What's The Deal? As GNSS vulnerabilities rapidly evolve, Lower Earth Orbit (LEO) constellations are emerging onto the scene, resulting in many unique solutions poised to address various applications. Whether you plan to develop your own LEO PNT solution or integrate LEO PNT into your solution, it is critical to have a testing and integration plan in place from the very beginning. Orolia's subject matter experts, combined with the industry's leading software-defined platform, will ensure your success in deploying this much-anticipated technology. What is LEO PNT? LEO PNT is the use of signals, satellites, and constellations existing in Earth's lower orbit for Positioning, Navigation and Timing in systems. LEO PNT can be used for commercial or defense purposes, offering many stand-alone benefits, and additional capabilities when paired with traditional GNSS constellations. Although roughly eighty-six percent of operating satellites are in LEO, their utilization to support PNT-specific needs is relatively new from a historic perspective. LEO = Lower Earth Orbit PNT = Positioning, Navigation and Timing Why LEO PNT? GPS as we know it today has evolved and expanded beyond its original intent. To put it bluntly, relying solely on conventional GPS satellites just doesn't cut it anymore, especially when it comes to critical infrastructure and missions. Though there are several GPS alternatives on the market today, what most of them lack is the ability to operate independently with a high level of accuracy and resiliency. Two things that make LEO constellations different than those in other orbital regions are its shorter distance to earth and constant movement. This results in greater performance with effects on faster speeds, higher signal power, increased bandwidth, and decreased susceptibility to attacks. Additionally, commercial providers can offer more targeted and advanced features by funneling investments into research and development. One such feature is security, thanks to proprietary encryption methods and custom frequencies. Another benefit is the expectation to prioritize, maintain and improve upon technology that aligns with certain needs, translating to rapid development cycles. When you think about it, LEO PNT is really a no-brainer. What is LEO PNT? Why LEO PNT? How is LEO PNT Being Implemented? Constellation Development • Technology is utilizing satellites for PNT information more than ever • It is integral to to test their PNT systems before they ar e deployed • It is key to develop a test environment for LEO constellations alongside the development of the constellations themselves. • A flexible simulation system that can evolve is best equipped for the advent of new LEO constellations. How Simulation Can Aid Development • Constellation: Increase communication and available for testing ASAP • Receiver: View receiver power in GPS denied environments, view acquisition times, and cost savings • Systems: Vulnerability, repeatability, and acceptance/verification testing How is LEO PNT Being Implemented? Simulation of a New Constellation Software-Defined Test Environment It's a fact that LEO constellations require more satellites due to their operating mechanism. Hence why there are more satellites (like a lot more) in LEO orbit than there are in the GNSS constellations that have been simulated in the past. Traditional GNSS Simulators don't have the built-in architecture to support this large number of satellites, especially if you want to simulate multiple constellations simultaneously, which produces the most realistic scenarios. This is where software-defined simulators take the cake. It's important to understand that in a true software-defined system there are no fixed hardware channels limiting the number of satellites and frequency bands that can be generated. Some providers may use crafty language to make you think otherwise, so be sure to clarify this when choosing a simulator. Software-defined systems, such as BroadSim , gives you the flexibility to meet your LEO needs without feature-specific add-ons that generally take up more space. A simple software license upgrade gives you access to the new LEO constellation, allowing you to have integrated all-in-view testing between GNSS and LEO constellations. Whether you choose our turnkey BroadSim products or need a more customized BroadSim solution to meet your LEO requirements, you will always use the same intuitive user interface that you are familiar with. BroadSim for LEO PNT The Simulator Preferred by Engineers Here are some of the top reasons why software-defined simulators like BroadSim provide a more dynamic and future-proof solution when it comes to LEO PNT: 1 | Takes advantage of commercial off-the-shelf (COTS) products to evolve as new technology emerges 2 | GPU can handle the generation of more signals than a traditional FPGA-driven solution 3 | Can rapidly add new constellations and evolve existing ones 4 | New constellations can be incorporated with software instead of additional hardware 5 | Rather than focusing on hardware improvements, engineers can focus on simulation 6 | Upgrade cycles are possible more frequently LEO PNT Resources Webinar Tech Brief White Paper LEO PNT Resources Get a Leg Up on LEO PNT Safran Federal Systems is integrating new constellations for simulation today and can help do the same for yours.

Protect your PNT systems from GPS jamming and spoofing attacks with BroadSim GPS simulator. Defend against threats using software defined radio technology. Home • Applications • GPS Jamming and Spoofing GPS Jamming and Spoofing: Protect Your PNT Systems from Emerging Threats GPS jamming and spoofing attacks are a growing concern as the accessibility of software-defined radios (SDRs) has made these threats more widespread than ever before. In order to safeguard PNT systems from potential disruptions, it is crucial to conduct proactive testing against real-world interference. Understanding the Threats of GPS Jamming and Spoofing Attacks Interference in GPS systems, such as jamming and spoofing attacks, can pose serious threats to the reliability and security of navigation systems that rely on global navigation satellite systems. Spoofers can generate false signals that can mislead GPS receivers about their position, potentially leading to dangerous consequences. As these evolving threats continue to grow in sophistication, it is crucial for organizations to implement effective detection and mitigation strategies to protect their PNT systems and ensure the integrity of their GPS data. By understanding the potential impact of GPS jamming and spoofing , governments can better protect their critical infrastructure and uphold the reliability of accurate position data. What is the difference between GPS Jamming & Spoofing? Jamming involves the intentional interference with GPS signals, disrupting communication between satellites and receivers. This can result in inaccurate positioning data or a complete loss of signal. Spoofing involves the manipulation of GPS signals to deceive receivers into believing they are in a different location. Testing Against Real-World Interference Testing against real-world interference is crucial in ensuring the reliability and accuracy of GPS and GNSS systems. With the increasing threat of jamming and spoofing attacks, it is essential to detect and mitigate these interferences effectively. By replicating real-world environments and simulating simultaneous generation of jamming and GNSS signals, this mitigation technique can accurately assess the system's ability to withstand interference and ensure genuine signals are being received. This proactive testing approach is key to ensuring accurate position data and the uninterrupted functionality of PNT systems in the face of growing security challenges. Challenges & Limitations with Traditional Jamming Testing When it comes to traditional jamming testing for PNT systems, there are various challenges and limitations that organizations face. One of the main challenges is that traditional testing methods may be limited in their ability to accurately replicate real-world jamming scenarios, leading to potential gaps in assessing the resilience of GNSS signals. This highlights the need for more advanced technology to effectively protect PNT systems from the increasing threats of jamming and spoofing attacks. Users required to attach a separate signal generator for each interference waveform to be generated The number of interference sources is limited to the number of signal generators available Signal generators would need to be integrated into software or be operated real-time by an engineer Jamming power levels were determined based on what signal level was to be received at the receiver front end independent of the location of the simulated jammer or transmit power BroadSim : The Ultimate GNSS Jamming & Spoofing Simulator BroadSim is transforming GNSS testing by allowing simultaneous generation of jamming and spoofing GNSS signals— all within a single system, making it easier than ever to replicate complex real-world environments. With BroadSim, generate high-fidelity interference signals across multiple types, including Carrier Wave , Additive White Gaussian Noise (AWGN), IQ File Playback , and more . Featuring intuitive Skydel software control and 4 RF outputs, BroadSim supports multiple simultaneous constellations. Hundreds of interference signals can be generated with 1 RF output Each interference signal within 1 RF output can have different power levels, modulations, and locations Jamming can be turned on and off through the Skydel GUI and API during runtime Users can specify the location, power, and movement of jamming transmitters and BroadSim will calculate the received power at the receiver based on the location to the transmitted and user-selected loss model Enables users to create real-world threat scenarios to better support the warfighter A Look Inside BroadSim Jamming Scenario Jamming Scenario Play Video Facebook Twitter Pinterest Tumblr Copy Link Link Copied Our team developed a plugin to showcase BroadSim’s hardware-in-the-loop (HILT) and advanced jamming capabilities via the Kerbal Space Program (KSP) computer game. BroadSim generates and transmits the corresponding RF signals to a GNSS receiver and a spectrum analyzer , whose data is collected and plotted on the same screen. 6 red spheres appear in the flight space, each representing a jammer with a unique frequency, power level, and modulation. The aircraft nears a jammer made up of CW tones offset by 1MHz with varying power levels. The aircraft in the video is controlled through a joystick. The path of the actual flight is shown by the red trail . As the airplane is maneuvered, its real - time location is sent to BroadSim. The reported location of the receiver is shown by the green trace and the spectrum from the spectrum analyzer is shown in the lower right-hand corner (center at GPS L1). When the aircraft flies directly through the jammer, the receiver is jammed to the point that it cannot track the GNSS signals and begins to drift in a straight line away from the jamming source. Simultaneous simulation of GNSS signals across multiple constellations can be achieved leveraging the Skydel Simulation Engine , including advanced jamming and spoofing . LEARN MORE Securing Your PNT Systems from GPS Jamming and Spoofing Attacks Protecting your PNT systems from the evolving threats of GPS jamming and spoofing requires advanced testing capabilities against real-world interference. Testing is particularly important for critical applications such as aircraft navigation, where false location information could have disastrous consequences. By utilizing signal generators such as BroadSim , warfighters can simulate different types of GPS interference, including jamming and spoofing, to ensure that PNT systems remain secure in the face of evolving threats. Leveraging the use of M-code for classified testing environments can further provide a secure platform for assessing the capabilities of PNT systems under various threat scenarios. By staying proactive and implementing comprehensive strategies, warfighters can better understand the vulnerabilities of their systems to defending against GPS spoofing and jamming to maintain the integrity of their operations.

GPS jamming and spoofing attacks pose a great risk to vessels at sea, causing them to drift into hostile waters unknowingly. A solution is here and available today, ready to defend and protect.
