This paper proposes a novel method for jointly detecting and automatically classifying multiple jammers using different modulation schemes. The method learns a representation of the radio environment encoded in a #Generalized #Dynamic #Bayesian #Network (#GDBN), with multiple GDBN models representing various jamming signals under different modulation schemes. The #CR-#UAV performs parallel online predictions and evaluates abnormality measurements using a Modified Markov Jump Particle Filter (#M-#MJPF) to select the best-fitting model explaining the detected jammer and recognize its modulation scheme. ---- ali krayani More details can be found at this link: https://lnkd.in/gR6Mh2XJ

New small UAVs standard A new I/O standard is being developed for small UAVs. The VNX+ standard is designed to fit into UAVs that can be launched from 5 in-diameter tubes and for CubeSats destined for orbit. It is going through the VITA standards process as VITA90 for release early this year, which would allow small modules with processors, GPUs, FPGAs, switches, sensors and RF to link together over a 110 GHz backplane, which could be optical. The standard has more pins on a tighter pitch than VPX VITA46, which is now 16 years old, and has a lower thermal budget of 25 W per slot. It follows the adoption of the SOSA 2 protocol at the end of last year. A sub-group of VNX+, called QMC, is developing a specification to extend the interface lines. This could be used to add extra I/O or for protocols such as 1553, CAN or video. Read more ➡ https://lnkd.in/eCsi5jzD #uncrewedsystemstechnology #VNX #UAV #uncrewedsystems #cubesats

Great to see a VITA Standard (VNX+, VITA 90) for small UAV to encourage an ecosystem of COTS suppliers with 25w power. May also have some application in small UGVs but larger platforms will require more compute. Enclosure would not fit a Jetson SoM.

Check out my cameo. Can you spot me? This video shows how Zendar's technology can detect pedestrians at long-range—something not possible with the technology in today's #cars. Anyone who has adaptive cruise control in their car will know what I mean. Even the best systems like #SuperCruise from General Motors have difficulty detecting and responding to objects far away. This is a problem when moving at high speeds—especially if traffic is stopped and the vehicle needs to brake quickly. I drove a #Cadillac Escalade last month with Super Cruise. It was able to detect stopped traffic ahead and start slowing down automatically, but not until I was far too close for comfort. Today's #automotive radar systems have a long way to go for safe and comfortable #autonomousdriving. Zendar is building a new kind of radar system that enables more comfortable driver assistance technology like adaptive cruise control. This same radar technology will be crucial for enabling the self-driving vehicles of the #future.

AI processing board for UAV thermal cameras Teledyne FLIR has developed a video processor for AI algorithms to use in its thermal cameras. The FLIR AVP video processor weighs 5 g and is based around the QCS8550 mobile processor from Qualcomm, which has been optimised for UAV and robot sensors. It runs the Teledyne FLIR Prism AI and image signal pipeline (ISP) software libraries, and interfaces with the company’s Boson and Neutrino thermal infrared imaging camera modules, as well as a wide range of popular visible cameras. The FLIR Prism AI model has been trained on the world’s largest thermal image data lake of more than five million annotations to detect, classify and track targets or objects for automotive autonomy, automotive automatic emergency braking, airborne camera payloads and counter-UAV systems. Prism ISP is a set of image-processing algorithms that include super resolution, image fusion, atmospheric turbulence removal, electronic stabilisation, local-contrast enhancement and noise reduction for the cameras.

How do you increase #radar resolution while keeping costs low and size of units small? Zendar's answer is aperture. By coherently fusing data from two or more radar units strategically positioned on a vehicle, we achieve a much larger aperture than is possible in a single hardware device. Fusing only two medium-range radars, we outperform state-of-the-art imaging radars. With three or more radars, we rival #Lidar in resolution but at a much lower cost. #automotivetechnology #sensortechnology #radarsystems #radartechnology #adas #autonomousdriving #autonomousvehicles #automotivesoftware #automotivenews

🚀 Project Update: UAV Development and Flight Stabilization Hello everyone! I wanted to share with you the project I have been working on lately, along with my friends Cansu Aydın and Özlem Kaşıkcı. Our project was about integrating a flight stabilization algorithm into a model aircraft. For this purpose, STM32 microcontroller and PID control algorithm were used. As a result of our project, the stabilization algorithm for the roll axis of the aircraft was integrated. This helps the aircraft maintain its balance and provide a safer flight experience. #STM32 #PID #UAV #FlightStabilization #Robotics

Last week, Ommatidia LIDAR's CEO, Eduardo Margallo, and Hardware Area Manager, Carlos Sanz Moreno, attended the #MaPALDA Project annual meeting in South Korea 🇰🇷. This initiative, supported by a global consortium, is driving innovation in automotive LiDAR technology, with a focus on massively parallel FMCW LiDAR and its implementation through photonic integrated circuits. We had the opportunity to align our progress with our partners, IDNEO, Universitat Politècnica de València (UPV), Hanyang University, ALC, and Viewnyx. The backing from @CDTI_innovacion and the Korean Institute of Advancement of Technology (KIAT) reflects the project's significance in both the South Korean and Spanish automotive industrial ecosystems. By leveraging these collaborative efforts, we aim to make significant strides in advancing long-range and in-cabin 3D sensing. This meeting reinforced the importance of strong international partnerships and the role that advanced photonic technologies play in the future of mobility. We are excited to continue working together to further integrate these technologies into real-world automotive applications. #LiDAR #AutomotiveTech #MaPALDA #Innovation #Photonics #FMCW #OmmatidiaLiDAR #AutomotiveIndustry #ANT

ESCs – The Brain of Drone Propulsion 🧠🔌 Welcome back, innovators! Today, we're exploring the Electronic Speed Controller (ESC), the component that translates your flight controller’s commands into action by regulating motor speed. A reliable ESC ensures smooth and responsive flight. Understanding ESC Functionality: PWM (Pulse Width Modulation): ESCs control motor speed by varying the duty cycle of the PWM signal. This allows for precise control over the motor's RPM. Firmware: ESCs run on specific firmware that dictates their performance. Popular firmware includes BLHeli, BLHeli_S, and BLHeli_32, each offering different features and levels of customization. Protocols: Communication protocols like OneShot, MultiShot, and DShot determine how quickly and accurately the ESC can respond to signals from the flight controller. DShot is digital, providing faster and more reliable communication compared to analog protocols like OneShot and MultiShot. 🛠️ Tech Tip: Ensure your ESCs are compatible with your motors and battery. Opt for ESCs with features like Active Braking (Damped Light) for better control and OneShot or DShot protocols for faster communication with the flight controller. Additionally, look for ESCs with built-in telemetry to monitor performance parameters like temperature and current draw in real time. In the next post, we'll discuss the complete propulsion system and how to test it.
