Imagine asmall aerial drone navigating a field with electrical power lines. How will it see them? More importantly how will it avoid this significant obstacle in its flight path?
At the U.S. Army Combat Capabilities Development Command's Army Research Laboratory, researchers developed a novel sensor and software application to detect and avoid energized power lines in the vicinity of unmanned aerial system, or UAS. The goal is to provide autonomous systems sufficient time and distance to react, avoid wires and navigate follow-on maneuvers.
Army researcher David Hull developed the innovative approach using a unique configuration of field and 3-D sensors, in conjunction with low-power processing methods. This resulted in detecting power lines and informing the device's autopilot to prevent collision with the wires.
This method allows UAS equipped with these to use smaller, lower power and lower cost sensors to detect the location and Poynting vector (i.e. the directional energy flux density) of nearby power lines. This allows the UAS to autonomously avoid or navigate alongside the detected power lines.
While existing wire-detection and wire-avoidance technologies that use radar and/or optical sensors have had commercial success, they are known to be expensive, bulky, and power-intensive with technical limitations. The detection algorithm developed at the lab will result in size, weight, power and cost reduction.
By combining both sensing modalities in one sensor, Army researchers estimated the direction of power flow, something no traditional sensor can do, Hull said.
The lab recently announced a patent license agreement with Manifold Robotics, a startup company based in New York, who will produce the new technology for drone-based commercial applications.
Engineers and drone experts at Manifold Robotics said they intend to create a drone-based system that will detect power lines at a distance and determine their precise location to enable safe navigation. They said this will overcome the factors that limit the efficacy of drones in the vicinity of power lines and unleash their full potential for autonomous power line inspection as well as other Beyond Visual Line of Sight operations.
From a military perspective, UASs are increasingly used by Soldiers for a variety of missions. In many cases, these drones must successfully operate in urban environments with a high number of power lines in and around the area.
The development goal is to see significant improvement in the safe usage of aerial drones in close proximity to power lines and power grids. Researchers said they believe the licensed Army technologies will enable commercial and military drones to detect power lines at a greater distance. Additionally, the technology is expected to accelerate the development of drone applications such as power line inspection systems and freight delivery drones.

By: Mark Pomerleau The Air Force issued a formal proposal earlier this month for the Department of Defense's long-awaited cyber weapon system, known as the Unified Platform, sources tell Fifth Domain. DoD officials have said the Unified Platform is one of U.S. Cyber Command's largest and most critical acquisition programs to date. Industry officials have said it is necessary to conduct cyber operations and is critical to national security. Just as sailors rely on an aircraft carrier, pilots need airplanes or soldiers need tanks, cyber warriors require a system to which they launch their attacks. Pentagon leaders have said the Unified Platform will house offensive and defensive tools, allow for command and control, situational awareness and planning. Industry officials have referred to the programs as a “cyber carrier” used to launch cyber operations and intelligence, surveillance, and reconnaissance. But details on what the Air Force, which issued the request on behalf of Cyber Command, wants in a Unified Platform are scarce. Sources told Fifth Domain a formal request for proposal was released through the General Services Administration's premier enterprise Alliant Governmentwide Acquisition Contract vehicle, which “provides flexible access to customized IT solutions from a large, diverse pool of industry partners ... [and] allows for long-term planning of large-scale program requirements.” Under this model, GSA completes much of the initial contracting legwork and, in this case, allows the Air Force to focus on the specific technical requirements, sources said. Companies compete to be eligible for task orders under the Alliant contract and then GSA selects contractors who compete against each other for individual task orders on the final program. This means, only vetted companies would work on the program. Alliant is also designed to streamline contracts for IT projects only, eschewing some of the documentation and financials in typical contracts enabling faster awards. The Unified Platform proposal was only released to companies on the contract about two weeks ago, sources said, and is due in mid-July. Today, each of the individual services use their own disparate systems, many of which are not linked together. The spokesman added that efforts are underway to review and consolidate existing service and Cyber Command's platforms. Unified Platform seeks to take the best of breed of these and provide all cyber warriors a consolidated system. “In concert with US Cyber Command and all Services, the Air Force as Executive Agent is directing development and deployment to ensure timely and relevant full-spectrum capabilities for our cyber warriors,” an Air Force spokeswoman said. An Air Force spokeswoman said that the Air Force's Life Cycle Management Center will serve as the system integrator and will lead a multi-contractor, agile development/operations effort to launch and expand the Unified Platform. Currently, Lockheed Martin, Northrop Grumman, Raytheon and Booz Allen Hamilton are known to be competing for the contract. Sources said other companies may also be considering a bid. The Air Force, in its research and development budget for fiscal 2019, asked for $29.8 million for the Unified Platform program this year. It requested $10 million for fiscal year 2020 and $6 million in fiscal 2021. The total cost of the program is not immediately clear. Other companies are also working on Unified Platform prototypes in the interim. Enlighten IT Consulting, a Maryland based company, was awarded earlier this year a sole source contract to provide a Unified Platform prototype, Duane Shugars, Enlighten's vice president of operations, told Fifth Domain. Enlighten is providing a capability Cyber Command's cyber mission force is using in real world missions today in which they collect data, push it into their analytics to run and share it for intelligence fusion. As the command continues to grow and mature leaders have said it will need its own infrastructure to conduct operations. As recently as 2015, top Pentagon officials acknowledged Cyber Command did not possess a robust joint computer network infrastructure capability, a robust command and control platform and systems to plan and execute fast-moving, large-scale cyber operations. During his confirmation process to lead Cyber Command, Gen. Paul Nakasone said the organization needs its own infrastructure separate from the National Security Agency, which is currently co-located with Cyber Command and has traditionally shared personnel and infrastructure. “Operating under the constraint of the intelligence authorities that govern NSA infrastructure and tools would severely limit USCYBERCOM's ability to effectively support wartime cyber operations,” he said. https://www.fifthdomain.com/dod/cybercom/2018/06/29/cyber-command-moves-closer-to-a-major-new-weapon/

Nathan Strout WASHINGTON - The U.S. Space Force will begin sharing valuable space situational awareness data with the United Kingdom as part of Operation Olympic Defender, the service announced Aug. 14. Under a recently signed agreement, the Space Force will share it's Standardized Astrodynamics Algorithm Library with the U.K.‘s Ministry of Defense. SAAL is a collection of the Space Force's understanding of orbital physics and algorithms that helps the service predict the trajectories of objects on orbit. “Aggressive actions in space must be deterred through a multinational, coordinated effort, allowing for the defense and protection or our collective capabilities,” said Maj. Gen. DeAnna Burt, USSF director of Operations and Communications, in a statement. “Sharing the SAAL with our coalition partners enables greater cooperation and coordination between the U.S. and our Allies.” The agreement comes as part of Operation Olympic Defender, an American-led coalition of space-faring allies working together to deter hostile actions in space, strengthen deterrence against hostile actors and address the growing issue of orbital debris. Operation Olympic Defender was officially taken over by U.S. Space Command in May and is located at the Combined Space Operations Center at Vandenberg Air Force Base, California. The U.K. was the first nation to join Operation Olympic Defender and is the first to receive access to the SAAL. Under the new arrangement, that nation's Space operations Center will now be better able to collaborate with the Space Force, sharing algorithms and data to better predict orbital trajectories. The Space Force is looking to share the SAAL with more partners within Operation Olympic Defender. According to the announcement, the Secretary of the Air Force's International Affairs Office, SPACECOM and the Space Force have recognized a new framework that will allow other coalition partners to begin receiving SAAL. SPACECOM has signed a number of space data sharing agreements with other countries in recent months. https://www.c4isrnet.com/battlefield-tech/space/2020/08/18/space-force-to-begin-sharing-technical-space-data-with-uk/
