Christmas Spirit Foundation executive director Rick Dungey on bringing cheer to military families and how viewers can help. The top U.S. commander for the Middle East said Thursday that the United States will keep the current 2,500 troops in Iraq for the foreseeable future, and he warned that he expects increasing attacks on U.S. and Iraqi personnel by Iranian-backed militias determined to get American forces out. Marine Gen. Frank McKenzie said in an interview with The Associated Press at the Pentagon that despite the shift by U.S. forces to a non-combat role in Iraq, they will still provide air support and other military aid for Iraq's fight against the Islamic State. Noting that Iranian-backed militias want all Western forces out of Iraq, he said an ongoing uptick in violence may continue through December. Gen. McKenzie, commander of the United States Central Command, testifies before the House Armed Services Committee on the conclusion of military operations in Afghanistan and plans for future counterterrorism operations on Wednesday, Sept. 29, 2021, on Capitol Hill in Washington.

Ethiopia's 13-month war has seen yet another dramatic turn as the federal government's counteroffensive against fighters from the northern Tigray region has made substantial advances, reversing the spectacular gains made recently by the Tigrayan forces in their push southwards. State media said this week the country's "joint gallant security forces" had retaken the strategic towns of Dessie and Kombolcha, the latest in a series of battleground victories since Prime Minister Abiy Ahmed said last month he would head to the front line and urged Ethiopians to join the fight. As fighting drags on, the government, with its tiny air force of 22 combat-capable aircraft, seems to have also realised that air power and timely intelligence can make all the difference in a conflict – especially one fought over vast and often mountainous areas like in Ethiopia's north. Although there has been no official confirmation, analysts have pointed to credible reports saying Ahmed's government has reached out in recent months to manufacturers of cheap and efficient armed drones hoping that air power will turn the tide in its way. Photographic evidence has pointed to the presence of Chinese Wing Loong 2 Unarmed Aerial Vehicles or UAVs at Ethiopian military bases, while a Bellingcat investigation in August found strong indications that Iranian armed drones, along with their ground control stations, had been spotted at Semera Airport.

In recent years, high-speed navigation and environment interaction in the context of aerial robotics has become a field of interest for several academic and industrial research studies. In particular, Search and Intercept (SaI) applications for aerial robots pose a compelling research area due to their potential usability in several environments. Nevertheless, SaI tasks involve a challenging development regarding sensory weight, on-board computation resources, actuation design and algorithms for perception and control, among others. In this work, a fully-autonomous aerial robot for high-speed object grasping has been proposed. As an additional sub-task, our system is able to autonomously pierce balloons located in poles close to the surface. Our first contribution is the design of the aerial robot at an actuation and sensory level consisting of a novel gripper design with additional sensors enabling the robot to grasp objects at high speeds. The second contribution is a complete software framework consisting of perception, state estimation, motion planning, motion control and mission control in order to rapid- and robustly perform the autonomous grasping mission. Our approach has been validated in a challenging international competition and has shown outstanding results, being able to autonomously search, follow and grasp a moving object at 6 m/s in an outdoor environment

Saudi Arabia has appealed to the United States and its allies in Europe and the Gulf for resupplies of ammunition it uses to defend the kingdom against drone and missile attacks, the Wall Street Journal reported on Tuesday (paywall), citing US and Saudi officials. Riyadh has been using its Patriot surface-to-air missile system over the past several months to thwart weekly ballistic missile and drone attacks launched by Houthi rebels based in Yemen, the officials told the WSJ. But the kingdom's stock of Patriot missiles to intercept aerial attacks has run dangerously low. The call for resupplies comes after the US has scaled back a large of portion its military presence in the Middle East that shored up the kingdom's security as the administration of President Joe Biden pivots to counter China's growing prowess on the global stage. Though the US is expected to approve the Saudi request for more Patriot interceptors, Saudi officials told the Journal they are concerned that insufficient stocks could result in a successful missile or drone attack, costing lives in the kingdom or harming the Saudi economy by damaging its critical oil infrastructure.

Ground penetrating radar mounted on a micro aerial vehicle (MAV) is a promising tool to assist humanitarian landmine clearance. However, the quality of synthetic aperture radar images depends on accurate and precise motion estimation of the radar antennas as well as generating informative viewpoints with the MAV. This paper presents a complete and automatic airborne ground-penetrating synthetic aperture radar (GPSAR) system. The system consists of a spatially calibrated and temporally synchronized industrial grade sensor suite that enables navigation above ground level, radar imaging, and optical imaging. A custom mission planning framework allows generation and automatic execution of stripmap and circular GPSAR trajectories controlled above ground level as well as aerial imaging survey flights. A factor graph based state estimator fuses measurements from dual receiver real-time kinematic (RTK) global navigation satellite system (GNSS) and an inertial measurement unit (IMU) to obtain precise, high rate platform positions and orientations. Ground truth experiments showed sensor timing as accurate as 0.8 µs and as precise as 0.1 µs with localization rates of 1 kHz. The dual position factor formulation improves online localization accuracy up to 40 % and batch localization accuracy up to 59 % compared to a single position factor with uncertain heading initialization. Our field trials validated a localization accuracy and precision that enables coherent radar measurement addition and detection of radar targets buried in sand.

This week, in addition to covering all the Cyber Week deals we could find, we also reviewed some unique gadgets. Steve Dent and a licensed drone pilot toured the French countryside with the help of the DJI Mavic 3 drone, while Terrence O'Brien played with the Animoog Z app, a sequel ten years in the making. Also, Cherlynn Low played around with Android 12 to check out its new Material You design. Steve Dent spent some time with the DJI Mavic 3 and a licensed drone pilot in the French countryside to see what the new device is capable of. He reports that not only is the Mavic 3 the easiest DJI drone to fly, but the large 4/3 sensor and dual camera system produce incredible footage – and the 46 minutes of range is double the time that the previous model could capture.

Active Position Estimation (APE) is the task of localizing one or more targets using one or more sensing platforms. APE is a key task for search and rescue missions, wildlife monitoring, source term estimation, and collaborative mobile robotics. Success in APE depends on the level of cooperation of the sensing platforms, their number, their degrees of freedom and the quality of the information gathered. APE control laws enable active sensing by satisfying either pure-exploitative or pure-explorative criteria. The former minimizes the uncertainty on position estimation; whereas the latter drives the platform closer to its task completion. In this paper, we define the main elements of APE to systematically classify and critically discuss the state of the art in this domain. We also propose a reference framework as a formalism to classify APE-related solutions. Overall, this survey explores the principal challenges and envisages the main research directions in the field of autonomous perception systems for localization tasks. It is also beneficial to promote the development of robust active sensing methods for search and tracking applications.

The House minority leader blasted Democratic leadership, saying the current policy is'creating another Syria' in the Middle East. The United States military conducted a drone strike in Syria targeting a senior al-Qaeda leader and planner, a CENTCOM spokesperson says. "U.S. forces conducted a kinetic strike near Idlib, Syria, December 3, targeting a senior al-Qaeda leader and planner," CENTCOM spokesperson Captain Bill Urban told Fox News Digital in a statement. "The strike was conducted using a precision strike method from MQ-9 aircraft." Urban added that an "initial review of this strike indicates the potential for possible civilian casualties."

With technological advancement, drone has emerged as unmanned aerial vehicle that can be controlled by humans to fly or reach a destination. This may be autonomous as well, where the drone itself is intelligent enough to find a shortest obstacle-free path to reach the destination from a designated source. Be it a planned smart city or even a wreckage site affected by natural calamity, we may imagine the buildings, any surface-erected structure or other blockage as obstacles for the drone to fly in a straight line-of-sight path. To address such path-planning of drones, the bird's eye-view of the whole landscape is first transformed to a graph of grid-cells, where some are occupied to indicate the obstacles and some are free to indicate the free path. We propose a method to find out the shortest obstacle-free path in the coordinate system guided by GPS. The autonomous drone (AutoDrone) will thus be able to move from one place to another along the shortest path, without colliding into hindrances, while traveling in a two-dimensional space. Heuristics to extend this to long journeys and 3D space are also elaborated. Our approach can be especially beneficial in rescue operations and fast delivery or pick-up in an energy-efficient way, where our algorithm will help in finding out the shortest path and angle along which it should fly. Experiments are done on different scenarios of map layouts and obstacle positions to understand the shortest feasible route, computed by the autonomous drone.

When it comes to emergencies, first responders don't have much time to think, whether it be a fire or search-and-rescue mission, and that's why Switzerland-based Fotokite has developed a fully autonomous tethered drone. Called Sigma, it was built using the NVIDIA Jetson platform and specializes in covering the vast majority of situations where first responders need an aerial perspective during an emergency. Not just a standard autonomous drone, this one comes equipped with a thermal camera capable of determining where a fire is, as well as where the safest location to enter or exit a structure would be. The drone can automatically highlight hotspots that need attention and guiding firefighters on where water is needed most, even through heavy smoke or with limited visibility. Everything from autonomous flight and real-time data delivery to the user interface and real-time streaming is made as simple as pushing a button, which means first responders can focus on saving lives and keeping people safe.
