NIAS and NASA test the Next Phase of NASA’s UAS Traffic Management System

Tests for NASA’s Unmanned Aircraft System (UAS) Traffic Management (UTM) system are being conducted at the six UAS test sites in the “Technology Capability Level 2 (TCL2) National Campaign.” The first tests were held at the Nevada Institute for Autonomous Systems.

NCSO uses UAV to find missing man

After receiving a call about a man who was missing in the woods, the Navajo County Sheriff’s Office in Arizona deployed their drone for the search. The disoriented man was found in about 45 minutes.

Transforming a Drone Company into a Data Company

Kespry says they are “focused on making it easy to capture, process, use and share high-resolution information from the field.” They offer “a fully autonomous aerial intelligence system” that tries to eliminate the need to integrate multiple systems from multiple vendors. In effect, their complete drone solution makes them more of a data company than a drone company.”

DARPA program to allow for mid-flight multitasking drone missions

A small UAS can often carry only one payload due to power, weight, and size constraints. Under the CONverged Collaborative Elements for RF Task Operations (CONCERTO) program, DARPA is looking at multiple payloads that share common RF components. BAE Systems has been awarded $5.4 million in contracts to help develop technology that allows operating modes to switch mid-flight. See the video: CONCERTO Concept of Operations

Close encounters of the drone kind becoming more common, U of C study says.

A new University of Calgary study finds there are more drones in the air than manned aircraft. There were 355 drone incidents reported in Canadian airspace between November 2005 and December 2016, and 22% of them involved close encounters between drones and piloted aircraft. Most incidents involve non-licensed operators.

Will Hydrogen Fuel Cells Help Drones Stay in the Air?

Three options today for increasing electric UAV time-in-the-air are tethered devices, solar power, and in-the-field rapid battery replacements. However, fuel cell power systems are gathering steam and two private companies are innovating and offering products: Protonex, based in Massachusetts, is focused on Proton Exchange Membrane (PEM) technology for small, light UAV applications; China-based MMC is currently manufacturing and distributing two models of fuel cells.

Watch A Very Vulnerable $140 Quadcopter Drone Get Hacked Out Of The Sky

Researchers at the Cyber-Physical Systems Security Lab at the University of Texas at Dallas hacked into a small quadcopter and took control. UT Dallas researcher Junia Valente said, “The device contains an open access point not protected by any password and a misconfigured FTP server that allows unauthorized users to read and write to the drone filesystem. One of the attacks we did was precisely to overwrite sensitive system files to gain full root access.”

Five reasons why fuel cell powered UAVs beat internal combustion fuel systems

A ScanEagle UAV manufactured by Boeing subsidiary Insitu has been tested with a Ballard Power Systems’ fuel cell system. Ballard lists five advantages that fuel cell propulsion of UAVs has over internal combustion systems.

North Dakota UAS Park Welcomes Northrop Grumman as Anchor Tenant

The Grand Sky Unmanned Aerial Systems (UAS) Business and Aviation Park, located near Grand Forks, North Dakota has welcomed new tenant Northrop Grumman to a 36,000 square-foot facility. The park has access to Grand Forks Air Force Base, where Northrop Grumman provides systems and technology to the U.S. Air Force, including the RQ-4 Global Hawk.

Backyard skinny-dippers lack effective laws to keep peeping drones at bay

A woman returned to her home in Darwin from an evening gym session, got undressed, and began to enjoy her secluded backyard pool. Soon, a small camera-mounted quadcopter appeared overhead. She doesn’t know who was operating the drone.

In Australia, the Civil Aviation Safety Authority (CASA) does not prevent drones from flying over private property. Australia lacks a tort of privacy so even if she could find him, the woman couldn’t sue the drone operator for a breach of privacy.

Software allows for use of drones and insect biobots to map disaster areas

North Carolina State University researchers have created the hardware and software to use UAVs and insect cyborgs (or biobots) as a way to map areas like collapsed buildings after a disaster. Biobots could move freely within a defined space and map the area as they go.

We talk with Dr. Gould about the research the NRL is conducting with fuel cells and the Ion Tiger unmanned air vehicle. We learn how fuel cells produce electricity, and the reasons fuel cells are attractive for unmanned aircraft. Dr. Gould also explains the application of additive manufacturing to fuel cells, future research projects, and the availability of the hydrogen used as the fuel.

Dr. Gould earned his Ph.D. in Chemical Engineering from the University of Michigan in 2007 and his B.S. in Chemical Engineering from the Colorado School of Mines in 2002.  His research interests include additive manufacture of fuel cells, fuel cell recovery processes, bipolar plate design, open cathode fuel cells, and hydrogen safety. He was awarded the prestigious 2013 Delores M. Etter Top Scientists & Engineers of the Year Award for his work on fuel cells.

This Airobotics ‘homing’ drone flies and lands without any need for a human

Tel Aviv-based Airobotics wanted to build a drone that required no human operator. One that could take off, fly pre-programmed flights for up to 30 minutes, and then land without human assistance. The company now says they have “developed a platform that is fully automated, industrial grade, on-demand and multi-purpose.” The Airobotics 1 video shows the automated landing box and a robotic arm for automatic payload and battery exchange.

Amazon patents drones with telescoping landing legs and foldable propellers

If a drone lands on a sloping surface, it could fall over. But an Amazon patent contemplates independently telescoping legs that would allow it to stay level. Such legs could also act as a shock absorber, and be tipped with spikes, screws, suction cups, or magnets to grip different surfaces. Another Amazon patent shows adjustable winglets on propeller tips for flight efficiency.

US demos ‘one of the world’s largest’ micro-UAV swarms

The U.S. Department of Defense (DOD) is continuing to develop autonomous swarming drones.

Originally designed at MIT Lincoln Laboratory in 2013, the Perdix micro-drones have been air-dropped from an F-16 in 2014, and an F/A-18 in 2016. In its Perdix Fact Sheet [PDF], DOD says:

“Perdix are not preprogrammed, synchronized individuals.  They share a distributed brain for decision‐making and adapt to each other, and the environment, much like swarms in nature. Because every Perdix communicates and collaborates with every other Perdix, the swarm has no leader and can gracefully adapt to changes in drone numbers. This allows this team of small inexpensive drones to perform missions once done by large expensive ones.”

Capturing the Swarm

The CBS television program 60 Minutes was allowed to film a swarm of 100 Perdix autonomous drones. The number of drones, their speed, and their unpredictable behavior made capturing them on video more difficult than anticipated!

Drone Registration Marks First Anniversary

December 21, 2016, marked the one-year anniversary of the FAA web-based drone registration system. More than 600,000 owners have registered and the FAA calls the system “an unqualified success.” Also, “The rule and the registration system were primarily aimed at the thousands of drone hobbyists who had little or no experience with the U.S. aviation system. The agency saw registration as an excellent way to give them a sense of responsibility and accountability for their actions. The agency wanted them to feel they are part of the aviation community, to see themselves as pilots.”
