Orolia Defense & Security was selected by the U.S. Air Force Guided Weapons Evaluation Facility to deliver a BroadSim Wavefront for CRPA testing of networked, collaborative, and autonomous weapon systems being developed under the Golden Horde program. U.S. Air Force Procures Orolia’s CRPA Testing Solution ROCHESTER, NY, February 15, 2022 DISTRIBUTION A: Approved for public release; distribution unlimited Orolia Defense & Security , the No. 1 provider of software-defined simulation solutions for navigation warfare, was selected by the U.S. Air Force Guided Weapons Evaluation Facility to deliver a BroadSim Wavefront. BroadSim Wavefront is a pillar of innovation among Orolia’s Skydel-powered advanced GNSS simulators. The GWEF provides laboratory testing and simulation tools for developing precision-guided weapon technology, including a comprehensive scope of GPS/INS systems and integrated components like sensors, signals of opportunity and Controlled Reception Pattern Antennas. CRPAs are fundamental in many platforms due to their enhanced protection against electronic attacks in NAVWAR environments. The Broadsim Wavefront simulator will be integrated into a test environment for networked, collaborative and autonomous weapon systems being developed under the Golden Horde program. Golden Horde is one of four Air Force Vanguard programs designed to rapidly advance emerging weapons systems and warfighting concepts through prototype and experimentation. Of the several capabilities the GWEF required, features such as low-latency hardware-in-the-loop, automated calibration, and the flexibility to quickly integrate future signals and sensors were the most critical and serve as a key reason Orolia’s BroadSim Wavefront was selected. This system will also be capable of testing eight-element CRPA systems, eight simultaneous Fixed Radiation Pattern Antenna systems, or a combination of CRPA and FRPA systems. “When designing BroadSim Wavefront, we re-imagined every aspect for the user,” said Tyler Hohman, director of products for Orolia Defense & Security. “Though the GWEF unit contains eight nodes (corresponding to each antenna element), it can be scaled from four to 16 antenna elements. One of the greatest advancements is our continuous phase monitoring and compensation technique. It automatically monitors, aligns and adjusts the phase of each RF output continuously throughout the duration of a scenario.” Watch the Skydel Wavefront calibration tutorial on Orolia Defense & Security’s YouTube channel. “Gone are the days of re-calibrating each frequency on your system, limiting your scenario duration or re-calibration every time you power cycle your system,” added Hohman. “Simply turn the system on, start the scenario, and your Wavefront system phase aligns and remains aligned for the entirety of the test.” Leveraging the Skydel Simulation Engine , BroadSim Wavefront also supports high-dynamics, MNSA M-Code, alternative RF navigation, open-source IMU plug-in and 1000Hz iteration update rate. “Because of the software-defined architecture, many upgrades don’t require additional hardware, which has been a crucial advantage for customers who are already using this solution,” Hohman said. The next generation of CRPA testing is led by BroadSim Wavefront. For more information, visit www.oroliads.com/broadsim-wavefront .

More space missions are taking place in Lower Earth Orbit (LEO). Newer, more advanced receivers are needed to have sufficient PNT capabilities. Doppler shifts experienced on these missions will be high, however, robust testing to ensure mission success is achievable... Home • PNT Library • Doppler Effects on Spaceborne PNT Applications Doppler Effects on Spaceborne PNT Applications DOWNLOAD PDF By Joshua Prentice Since the very first space missions positioning, navigation, and timing (PNT) have been crucial for spaceborne applications. Traditionally, space vehicle PNT has been achieved through various combinations of ground stations, optical navigation, onboard high-precision clocks, inertial measurement units, and other methods. Only recently, however, has existing global navigation satellite systems (GNSS) been added to that list. GNSS constellations were designed to provide PNT for Earth-borne applications taking place on the ground, sea, or in the atmosphere. As such, those GNSS waveforms are primarily aimed toward the Earth, but there is a small amount of spill-over of the main lobe beyond the silhouette of Earth and into space. Additionally, the side lobes of most GNSS waveforms are also broadcast into space beyond Earth. Because these signals are visible from orbit, they can conceivably be used for the PNT of space vehicles. In terms of spaceborne navigation from GNSS constellations, there are generally two main orbital regions of concern. Altitudes between Earth and the GNSS altitude, known as being under the “canopy”, and altitudes above the GNSS canopy as shown below in Figure 1. Figure 1: Below and Above the GNSS Canopy When orbiting the Earth underneath the GNSS canopy the receiver antenna must point “skyward” towards the GNSS constellations. This scenario is more closely related to traditional GNSS navigation, although satellites will rise and set more frequently. The full spectrum of these signals is available with the advantage of stronger signal strength compared to surface and low-atmospheric operations. In scenarios where the receiver vehicle is orbiting above the GNSS canopy, navigating based on GNSS constellations becomes much more difficult as the only available portions of the waveform are the main lobe spill-over and the side lobes. For simplification and to limit the scope of this tech brief, the primary area of concern will be space vehicles in geocentric orbits beneath the GNSS canopy. When navigating from GNSS signals Doppler shift is always present no matter how close to the GNSS canopy the receiver is. However, when the navigating receiver is traveling at velocities necessary to maintain a stable orbit, the Doppler shift is much greater. Figure 2: Doppler shift diagram The Doppler shift change in frequency can be expressed as (Parker, 2017): In equation (1) 𝑓₀ is the source carrier frequency, Δ𝑣 is the relative velocity of the space vehicles, and 𝑐₀ is the speed of light. This equation does not account for ionospheric and tropospheric effects encountered when GNSS signals pass through the Earth’s atmosphere. When considering equation (1) for multiple scenarios and orbital altitudes, the speed of light is a constant, and depending on the GNSS constellation being used so is the source carrier frequency. Thus, the biggest factor affecting Doppler shift is the relative velocity of the space vehicles. Because the satellites that make up GNSS constellations are held to very strict orbits with known orbital velocities and those orbits are maintained throughout the lifetime of the constellation, the determining factor of the relative velocity for any given mission is the orbital velocity of the receiver vehicle. It follows that the goal in computing a theoretical maximum Doppler shift a spaceborne receiver may encounter is to maximize the relative velocity between the receiver vehicle and the GNSS vehicle. A scenario that would accomplish this would be a receiver vehicle in very low earth orbit (VLEO) tracking GNSS signals. Spaceborne missions taking place in LEO are a unique case of GNSS PNT due to the high relative velocity compared to the GNSS constellation vehicles while still being beneath the GNSS canopy. The dynamics of such a scenario are some of the highest that a receiver may experience during typical PNT operations. As such, the Doppler search space of receivers deployed in LEO must be much wider than needed for ground, sea, and airborne missions. One example of a very low earth orbit mission (VLEO) is the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE). The GOCE mission required extremely precise orbit determination to carry out its scientific objective of mapping Earth’s gravity field to an accuracy of 1-2 cm. The GOCE space vehicle maintained an average orbital altitude of 255 km, placing the average orbital velocity around 8 ᵏᵐ⁄ₛ (European Space Agency, 2022). The GOCE mission tracked GPS signals to assist in orbit determination. GPS satellites orbit at an altitude of 20,200 km with an average orbital velocity of roughly 4 ᵏᵐ⁄ₛ (US Space Force, 2022). Figure 3: GOCE Missions in VLEO have much shorter durations than other spaceborne missions due to the need for constant orbital maintenance maneuvers to counteract the atmospheric drag, and as such, it can be considered the lower limit of possible orbital altitudes. To estimate a maximum possible Doppler shift the worst possible case scenario would be the receiver satellite travelling in exactly the opposite direction (±180°) of the GNSS vehicle. While this is generally a very rare situation some space vehicles do travel in non-standard orbits, so it is possible. Thus, the relative velocity of the space vehicles can be expressed as: Where: So that: Note that all velocities are expressed as linear for simplification. With an established relative velocity, the maximum estimated Doppler shift can be calculated using the following values: Calculating the Doppler shift using the equation (1) results in: With a worst-case-scenario Doppler shift of 63 kHz, it is imperative to ensure the receiver being placed into orbit can perform under such conditions. Skydel Simulation Engine of the BroadSim product line is capable of simulating spaceborne scenarios, even under conditions where Doppler shift is maximized. One of the default vehicle profiles within Skydel is an Earth-orbiting spacecraft with highly customizable Keplerian elements to define the exact orbit thereceiver vehicle will experience. Should the default spacecraft profile not provide enough customization, Skydel can also be interfaced through hardware in the loop (HIL) where exact positions are pushed to the simulator to simulate the specific trajectory of a receiver vehicle. Unlike some simulators where the Doppler shift will have to be either predetermined or manually added to the scenario, Skydel handles Doppler, ionospheric, and tropospheric effects automatically based on the scenario without requiring user input. Figure 4: Skydel Screenshot LEO and VLEO missions are becoming more and more popular especially in the fields of PNT, from both from a provider and user standpoint. To make sure those missions will have sufficient PNT capabilities advanced receivers will need to be used and new receivers will be developed to fill specific roles and advance current capabilities. While the Doppler shifts experienced by receivers on these missions will be high, robust testing to ensure mission success is capable using BroadSim simulation products powered by Skydel. Commonly Asked Questions About Doppler Effects Why are GNSS signals now being used for space navigation? Historically, space vehicles relied on methods like ground stations, inertial sensors, and onboard clocks for navigation. GNSS was originally designed for Earth-based applications, but signal spillover (main lobe and side lobes) into space now allows satellites to use GNSS for autonomous navigation. Why is this topic important? Reliable, autonomous PNT in space is critical for military satellites, ISR platforms, and scientific missions, especially when access to ground-based navigation aids is unavailable or denied. What causes Doppler shift in spaceborne GNSS reception? The Doppler shift arises from the relative velocity between the receiver spacecraft and the GNSS satellite. The faster the receiver moves in orbit, the more pronounced the frequency shift in received GNSS signals. References European Space Agency. (2022). GOCE Facts and Figures.

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.

This whitepaper explains the importance of simulation in response to new constellations, the benefits of developing a test environment alongside the development of the constellations, and how a flexible system is best equipped for the advent of new LEO constellations... Home • PNT Library • Developing Simulation Environments Alongside New LEO Constellations Developing Simulation Environments Alongside New LEO Constellations DOWNLOAD PDF By Alaiya Tuntemeke-Winter As more technology utilizes satellites for PNT information, it is integral to develop ways to test the functionality of PNT systems before they are deployed. It has become increasingly useful 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. Developing simulation hand in hand with developing the constellation itself has several advantages. Simulation can be implemented at various stages of the process. By developing new constellations and simulation simultaneously, the PNT system can be thoroughly tested before the satellites are deployed. This can further streamline the process between the developers of the constellation and the receivers with quick feedback loops to assist in the design. It can lead to increased communication with the receiver developers and give more insight in addition to modeling. It also means that simulation capability can be available along with the introduction of the constellation itself. In the past, there have been instances of the constellation being deployed but there being few ways for the receiver manufacturers to test their solutions, slowing down the development process. By testing using simulation, developers can test functionality early in the development process, rather than awaiting deployment of the constellation for the chance to field test; receivers and systems can be tested during development for common problem scenarios, such as GPS denied environments via canyons or other outages as well as other types of vulnerabilities. This can give developers a head-start in vetting potentially unforeseen issues the receiver may experience using the new constellation. After implementation simulation can be used to repeat any problems encountered in field tests for faster and more effective testing. Fixes can be implemented in a lab setting before going out again for field testing. This can save time and resources, as there is no need to go all the way to the field test stage every time a problem arises or to test a fix. Using a simulation test bed helps to speed up the development process and to save time and money throughout. Developing simulation alongside the development of the constellation gives simulators the time they need for the capability to be ready when the constellation deploys. If simulation development does not begin until after the constellation is deployed, the development of receivers that can use the new constellation data may be slowed by the inability to test and collect data. Some types of simulators take more time to develop the ability to simulate new constellations, as they may need to develop new software, hardware, or a combination of both. Parallel development of the new constellation and the simulation test bed allows for both simulation capability and constellation availability to time align in the development process. The BroadSim product line provides a dynamic simulator within its software-defined architecture. It is “future-proof” as it can grow and change with new constellations or changes in old ones. It also takes advantage of commercial off-the-shelf (COTS) products to increase system performance. This means two things; one, rather than focusing on hardware improvements, the engineers can focus on the simulation side of the system. Two, upgrade cycles are possible more frequently. BroadSim provides open-source libraries and plug-ins to increase the capability of their simulation solution. One major benefit of software-defined simulation systems regarding LEO constellations is that the GPU can handle the generation of more signals than a traditional FPGA-driven simulation solution. This is because in a true software-defined system there are no fixed hardware channels limiting the number of signals that can be generated. This is especially relevant in LEO constellations as there are more satellites in LEO orbit than there are in the GNSS constellations that have been simulated in the past. Another benefit is that if the limit is ever reached, a GPU can simply be added, and the same simulation tool can continue to be used. This leads to another benefit – the flexibility of the system. New constellations can be incorporated with software instead of additional hardware. This means when new constellations are complete, developers can access those new constellations with a mere software update. Software-defined simulators evolve to support LEO constellations and more rapid development. How simulation can aid development Examples of software-defined simulation in BroadSim BroadSim is an example of this flexibility in motion. With BroadSim, new constellations and signals become available in the tool as they are introduced or are more commonly used in receivers, such as QZSS, BeiDou, and M-Code. Simulators allow users to thoroughly test how receivers or whole systems work during specific scenarios, giving them the ability to see all-in-sky satellites and terrain effects, and provide refresh rates that translate into real-time processing for fast-moving applications. This makes it possible to test acquisition time, view relative receiver power data, and collect other relevant data to further development, as well as automate commands to speed up testing. The flexibility of the system is demonstrated by its proven ability to simulate existing LEO constellations. Using BroadSim powered by Skydel, there are multiple built-in ways to create LEO constellations. One such way is using BroadSim’s plug-in tool, which has already seen success. This tool allows users to develop features and integrate them into the BroadSim user interface and real-time simulation engine. BroadSim also provides the ability to modify existing constellations with custom signals and the addition of data sets to manipulate orbital and ephemeris data. In the future, a growing list of constellations will become available for selection within the tool. Safran Federal Systems is integrating new constellations today, and can help do the same for yours. BroadSim Simulation In conclusion, developing simulation capability alongside the development of constellations is to the advantage of the engineer who will be able to test without delay. Those simulators can aid in the design process by allowing rapid testing and development, speeding up time to market, and increasing cost savings by reducing field test cycles and hours. Software-defined simulators are more equipped to handle LEO constellations. They are not limited in the number of signals they can produce via hardware; they are agile in that they can increase available constellations and capability without needing any hardware upgrades. New features and constellations are available with just a software upgrade, and the user community can create new ways to use the tool using open-source plug-ins to meet their needs. BroadSim already has initial support for LEO simulation using the plugin tool and Safran Federal Systems is actively taking inquiries from users and providers to partner with them and integrate their solution.
