Equipment Pointing & Radar Directional Capabilities For Defense Applications DOWNLOAD PDF By Anthony Full Problem We Solve In order to properly orient a vehicle-mounted weapon, or any radar system that relies on global navigation satellite signals, vehicle crews need accurate heading data to point their equipment. Operators may start with estimating trajectory paths, but it is hard to know exactly where their equipment is pointing because any slight change in angle causes a massive change in impact location or radar direction. Operating in a GNSS-denied environment also presents challenges, and it would be time consuming and potentially dangerous to wait for clean signal reception. Inertial Navigation Systems (INS) that provide true north-finding capabilities is an extremely helpful and flexible alternative because it allows vehicles to have high accuracy orientation capabilities for their mounted weapons or radar payloads. They can minutely adjust their angles or rotation without the aid of GPS, and without being susceptible to vibrations and shocks. Why Is It Important Having precise orientation capabilities is critical in ensuring weapons effectively designate their targets. Likewise, having accurate orientation in radar systems is essential in the process of geographically locating objects. The act of orienting a vehicle weapon or radar is not trivial: accurate shooting requires complex calculations from numerous factors including determining level ground, finding the north pole, measuring wind speed and direction, and elevation of the target. Highly accurate equipment pointing can mean the difference between mission failure and success. Therefore, having a robust navigation system that can provide heading data in real time is of paramount importance for defense applications. Given that the National Intelligence Council has identified an increasing trend in jamming and spoofing attacks, the need for navigation systems to be able to operate independent of GPS signals is also becoming important. Inertial navigation systems need to be able to operate in both normal conditions as well as GPS-denied environments. Of course, there are different grades of accuracy for equipment pointing depending on your needs. And we’ll cover the most relevant solutions next. How We Solve it When it comes to navigation systems that can provide heading data in real time Safran has field-proven solutions for diverse defense applications. The Geonyx product incorporates HRG technology, unlike GPS, INS does not rely on external signals for navigation and heading. Instead, it uses motion sensors and rotation sensors to calculate the position, orientation and velocity of the vehicle based on internal data. The Geonyx will output pitch, roll, and heading data to the vehicles weapon system or to the vehicles radar system via ethernet. GEONYX INERTIAL NAVIGATION SYSTEM Geonyx is an INS solution for ground vehicles and artillery pointing systems, offering a virtually unlimited and maintenance-free lifespan. It can achieve a pointing accuracy of <0.5 mils thanks to HRG Crystal technology. It has quick and flexible alignment – even in GNSS-denied environments. DOWNLOAD PDF

Home • Applications • Electronic Warfare Electronic Warfare There are many forms of electronic warfare in today's modern battlefield. One of the more common arenas is within the Position, Navigation, and Timing (PNT) realm - or what our industry refers to as NAVWAR (Navigation Warfare). With expertise that goes back 30+ years, this is where Safran Federal Systems thrives. ​ NAVWAR and EW • Testing Capabilities • Field Solutions • Offensive Capabilities How does NAVWAR differ from other forms of Electronic Warfare (EW)? NAVWAR is a subset of Electronic Warfare that targets GPS and other PNT signals or sensors in which the warfighter depends upon. Typically, people think of GPS in the way that most people use it today – on a screen on their phone or in their car, getting you from point A to point B. But what people don’t realize is how just how many mission-critical systems rely on GPS to function, and how vulnerable it is to attack. For example, a warfighter's precise location is needed for rescue. If their systems are attacked electronically and they lose their GPS position, it can have devastating consequences. NAVWAR and EW Addressing today's challenges in Electronic Warfare From the lab to the field, Safran’s Electronic Warfare solutions back the warfighter at many crucial stages: Test, Detect, and Defeat. Safran’s proven expertise in GPS jamming & spoofing simulation and protection has enabled them with the ultimate toolkit for EW capability.

Valiant 153M GB-GRAM/GB-GRAM-M Interface Card Valiant 153M PRODUCT | GNSS TESTING & SIMULATION Compatibility GB-GRAM Type I GB-GRAM Type II GB-GRAM-M Type I GB-GRAM-M Type II Size 4.1" x 2.9" (length x width) Weight approx. 60 grams Power < 0.5W (without GB-GRAM/M) Operating Temperature -20 ͦ C to +65 ͦ C ANY QUESTIONS? GET QUOTE About Valiant 153M is a GB-GRAM/GB-GRAM-M (GB-GRAM/M) interface card that allows the simultaneous operation and testing of a commercial- off-the-shelf (COTS) receiver and a GB-GRAM/M. Both receivers are powered and communicate using a single USB mini cable. By integrating a COTS receiver onto the Valiant 153M, users can perform cross-checks to determine if the military receiver is connected and communicating data properly. Both receivers communicate via the onboard USB mini or RS-232 serial connectors. The Valiant test fixture was designed to be nearly the same size as the GB-GRAM/M type I card. Applications The Valiant 153M excels within valuable criteria for testing in lab and field test environments. COTS Receiver GB-GRAM/M The integrated COTS receiver allows test engineers to confirm that their setup and receiver is properly configured. By observing the data output, engineers can know for certain that their antenna, power, and communication is successfully connected to the Valiant interface card. From there, cross-checks can be performed to make sure the military receiver is reporting the same data as the COTS receiver. The COTS can also act as another unit under test (UUT) during the field test. It is slightly larger than the type I card so that the GB-GRAM/M can be fully placed inside the case. The Valiant 153M can be powered by a USB mini cable, or a 5V wall wart providing options for test engineers. Not only does the USB mini power the board and both receivers (legacy GB-GRAM) but it can also provide data communication for both the GB-GRAM/M and the integrated Ublox receiver. Finally, with one RF input, you can provide GPS signals to two receivers allowing for more UUT’s. The proper operation of the two receivers can be examined using Safran’s software suite, RxStudio. This software suite allows a user to communicate to the receivers simultaneously and visually examine their performance (C/No, SVs tracked, SVs used, LLA, time, code types, assurance, frequency, etc).

Home • Applications • GPS Jamming GPS Jamming Prepare for tomorrow. Find Vulnerabilities today. An increased number of GPS jamming and spoofing attacks have been reported and documented over the past five years. With high-quality software-defined radios (SDRs) becoming more affordable, hardware capable of GPS jamming and spoofing is more available than ever. It is critical to test your PNT systems against these attacks. BroadSim is a software-defined GNSS simulator that enables users to easily model true and spoofed signals. The Solution BroadSim is revolutionizing the way in which GNSS testing and simulation is performed yet again by enabling the simultaneous generation of jamming signals and GNSS signals all in one system. Generate complex spectrums by leveraging BroadSim’s 4 Tx outputs. BroadSim is capable of generating high fidelity jamming and interference signals of multiple types, provides Intuitive control using Skydel software and utilizes 4 RF outputs, each with multiple simultaneous constellations. Old jamming testing method without BroadSim 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 New jamming testing method with BroadSim Unlimited number 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 SDX GUI and API Users can specify the location and power 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 laydowns to better support the warfighter. Jamming Scenario Play Video Facebook Twitter Pinterest Tumblr Copy Link Link Copied For the Joint Navigation Conference (JNC) our engineers created and designed a plugin for the computer game Kerbal Space Program (KSP) which allowed for the demonstration of BroadSim’s hardware in the loop (HILT) capability as well as the new advanced jamming feature. The aircraft seen in the video is being controlled by user input through a joystick. The path of the actual flight is shown by the red trail. As the user is controlling the airplane in KSP, the computer is sending the location of that plane in real-time to BroadSim which is generating and transmitting the corresponding RF signals to a uBlox GNSS receiver and a spectrum analyzer. The receiver and spectrum analyzer data are simultaneously being collected by the computer and plotted on the same screen. 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). Within the flight space of the program were 6 red spheres as seen in the video. Each red sphere represents a different jammer. Each jammer has a different frequency, power level, and modulation. The jammer (red sphere) shown in the video is a group of CW tones offset by 1MHz with different power levels. Notice how the receiver responds when the user approaches and flies directly through the jammer. The receiver is jammed to the point in which it cannot track the GNSS signals and begins to drift in a straight line away from the jamming source. By leveraging the Skydel 1000Hz navigation engine and USRP radios, simultaneous simulation of GNSS signals across multiple constellations can be achieved, including advanced jamming and spoofing: GPS Open: L1-C/A, L1C, L1-P, L2-P, L2C, L5 GPS Encrypted: L1-Y, L2-Y, L1-M-AES, L2-M-AES, L1-MNSA, L2-MNSA GLONASS: G1, G2 BeiDou: B1, B2 Galileo: E1, E5a, E5b QZSS: L1-C/A SBAS: WAAS, EGNOS, MSAS DOWNLOAD
