Terra Drone Corporation has launched a new UAV and artificial-intelligence (AI)-based solution designed for maintenance of power transmission and distribution equipment.
The solution was developed based on market gaps identified after inspecting more than 90,000 kilometers of power lines beyond visual line of site (BVLOS) throughout the world.
Acquired data is automatically processed and analyzed by artificial intelligence algorithms trained to detect crossovers at the bottom of transmission lines, buildings and construction machinery.
The system identifies rust on bolts, loosening and missing tower parts, bird’s nests and more. It then generates a smart report highlighting areas that require action. The error (identified anomaly) detection system is accurate up to 92.5%.
The algorithm for an area is developed through a process identifying anomalies in a training data set of 1,500 images. This allows for a custom solution to be created for the end client where all pertinent anomalies are identified and reported.
The development and training of the algorithm only need to be completed once for a particular type of asset and can be implemented easily at different locations on similar assets.
With such a high-precision algorithm, the productivity of AI processing allows for fast actionable results to be provided to clientele. Clients also have the ability to identify the appropriate security protocols for data storage in either a cloud-based or on-premises storage environment. These protocols can then be implemented in a custom client-specific solution.

Power transmission and distribution companies must conduct periodic inspections of power line infrastructure to ensure reliable electric power distribution, although the conventional methods of deploying ground staff or low-flying helicopters to complete the inspections, they are typically cost-prohibitive. Conventional helicopter and boots-on-the-ground service also pose HSE concerns with low flying helicopters and people working in the field. UAV service and AI inspection can aid in minimizing HSE concerns by reducing the number of workers in the field and eliminate low level manned helicopter missions.
This solution has been built from ground up with the aim to simplify and streamline the maintenance work for transmission and distribution facilities.
The United States Federal Aviation Administration (FAA) has awarded air carrier and operator certification to UPS Flight Forward, an unmanned aircraft system (UAS) delivery company.
Through the DOT’s UAS Integration Pilot Program, the FAA has now approved a Part 135 operating certificate for UPS Flight Forward. This allows the company to perform revenue-generating package delivery activities within federal regulations.
UPS Flight Forward may now operate multiple drones under one certificate. Under Part 135, the company can deliver vital healthcare supplies including by flying beyond visual line of sight.
The UPS subsidiary immediately launched the first drone delivery flight by any company under Part 135 Standard at WakeMed’s hospital campus in Raleigh, N.C. That flight, using a Matternet M2 quadcopter, was flown under a government exemption allowing for a beyond-visual-line-of-sight (BVLOS) operation, also a first in the U.S. for a regular revenue-generating delivery.
UPS said it has proven the need for drone delivery in healthcare operations, where the shortest time in transit can improve efficiency and help healthcare professionals better serve patients.
The medical delivery program at WakeMed is the result of testing conducted by UPS and Matternet in August of 2018 as part of their participation in the UAS Integration Pilot Program (UAS IPP).
UPS partnered with Matternet to launch its healthcare delivery service on the WakeMed campus. The revenue-generating service demonstrated the business case for drone delivery of medical products and specimens.
Now, with its Part 135 Standard certification, UPS is ready to build on this application and expand to a variety of critical-care or lifesaving applications.

“This is history in the making, and we aren’t done yet,” said David Abney, UPS chief executive officer. “Our technology is opening doors for UPS and solving problems in unique ways for our customers. We will soon announce other steps to build out our infrastructure, expand services for healthcare customers and put drones to new uses in the future.”
The company will initially expand its drone delivery service further to support hospital campuses around the country, and to provide solutions for customers beyond those in the healthcare industry.
Part 135 Standard certification enables UPS to integrate drones into the UPS logistics network, creating potential for new applications in many industries. The company has a long-term plan with milestones that include:
expansion of the UPS Flight Forward delivery service to new hospitals and medical campuses around the country.
rapid build-out of ground-based, detect-and-avoid (DAA) technologies to verify drone safety, while enabling future service expansion.
construction of a centralized operations control center.
regular and frequent drone flights beyond the operator’s visual line of sight.
partnerships with additional drone manufacturers to build new drones with varying cargo capacities.
adding new services outside of the healthcare industry, including the transport of special commodities and other regulated goods.
“UPS is committed to using technology to transform the way we do business,” said Scott Price, UPS chief transformation and strategy officer. “UPS’s formation of a drone delivery company and application to begin regular operations under this level of certification is historic for UPS and for the drone and logistics industries.”
As a participant in the U.S. Transportation Department’s Unmanned Aircraft Systems Integration Pilot Program, the North Carolina Department of Transportation (NCDOT) partnered with UPS Flight Forward. As the operator, they have been engaged in delivery of healthcare supplies around a major hospital campus in Raleigh, North Carolina. The flights have focused on the delivery of blood for potentially life-saving transfusions, as well as other medical samples for lab work.
The company demonstrated that its operations met the FAA’s rigorous safety requirements to qualify for an air carrier certificate. This is based on extensive data and documentation, as well as test flights.
Skyfront’s Perimeter 4 long-range hybrid gas-electric drone this summer successfully performed the first civilian beyond-visual-line-of-sight (BVLOS) flight without visual observers under the FAA’s Part 107 rules.
The flight serves as a significant step toward the safe integration of unmanned aerial vehicles into the national airspace, according to the company.
During the round-trip flight, the Perimeter UAV flew over mountainous, rugged terrain along a four-mile stretch of the Trans-Alaska pipeline. The UAV maintained a constant above-ground altitude of 400 feet with multiple ascents and descents of 1,000 feet on 45-degree slopes. Radio-based telemetry, command and control of the vehicle was uninterrupted during the flight.
FAA representatives observed all aspects of the mission, including planning, system setup and ground-station operation. The Perimeter “did [the flight] safely, effectively and efficiently. It accomplished a beyond-visual-line-of-sight mission, and it was approved by the FAA,” said Robert Huber, program manager for the Integration Pilot Program (IPP) of the FAA.
“Today’s flight was a milestone in the unmanned community,” said Troy Mestler, CEO of Skyfront. “We at Skyfront are excited to be pushing the limits of unmanned aerial vehicles here in the United States.”
The Perimeter UAV was integrated with Iris Automation’s Casia collision avoidance system and was observed by Echodyne’s ground-based detect and avoid systems.
The University of Alaska Fairbanks and the Alaska Center for Unmanned Aircraft Systems Integration purchased the UAV and organized the flight over the pipeline, with the approval of the Alyeska Pipeline Service Company.
Kansas receives approval for first beyond-visual-line-of-sight drone flight in the nation using only onboard detect and avoid.
The Kansas Department of Transportation (KDOT) has received permission to conduct the first beyond-visual-line-of-sight (BVLOS) drone operation in the nation leveraging only onboard detect-and-avoid systems.
This is the first U.S. Federal Aviation Administration (FAA) authorized operation to fly without a requirement for visual observers or ground-based radar. It is the result of the 31-member Kansas UAS Integration Pilot Program (IPP) team efforts to advance drone technologies.
In a collaborative effort among Kansas State University Polytechnic Campus (K-State Polytechnic), Westar Energy, Iris Automation and KDOT, the Kansas IPP team will fly a nine-mile track to evaluate technologies to inspect power lines in rural Kansas. This approval is the first of its kind for long line linear infrastructure and is the first step to enable routine commercial infrastructure inspection across the state.
This is the first unmanned aerial vehicle (UAV) flight to leverage onboard sense and avoid systems alone for collision avoidance. It also marks the first required automated avoidance action.
Historically, all FAA-issued Part 107 BVLOS waivers have required visual observers or ground-based radar. These mitigations limit the possibility of true BVLOS flights, as they are typically prohibitively expensive and limit operations to pre-defined corridor areas with radar coverage.
This important milestone is facilitated by Kansas UAS IPP partner Iris Automation’s Casia onboard collision-avoidance system.
“The UAS industry has worked over 10 years to demonstrate the most significant commercial benefit of drone operations within the United States,” said Bob Brock, KDOT director of aviation. “We are proThe Applied Aviation Research Center on the K-State Polytechnic Campus, which assisted in development of the safety case that ultimately led to FAA approval, will be responsible for the training and flight operations with a cross-functional team from the KDOT IPP. Flights will take place over the next few months, providing the FAA with much-needed data on true BVLOS activity.d of the joint state, university and industry team that made this landmark decision possible.”
“The ability to fly BVLOS missions without ground-based radar or visual observers is a significant advancement, and Westar Energy views this as an opportunity to play a key role in shaping the future of UAS operations within the utility industry,” said Mike Kelly, Westar Energy Senior UAS coordinator. “Being able to operate under this waiver allows the Kansas IPP team the ability to research and develop truly scalable BVLOS UAS operations for the automated inspection of linear infrastructure.”
“We look forward to leveraging this waiver to integrate UAS technology into the transmission line inspection process,” said Kurt Carraway, UAS Executive Director of the K-State Polytechnic Applied Aviation Research Center. “We are certain that utilities will be able to quickly realize a return on investment while mitigating safety to their maintenance personnel and increasing the reliability of their infrastructure to the general public.”
“Flying rural missions like these without a human pilot onboard or costly radar on the ground is exponentially safer and more cost effective,” said Iris Automation CEO and Co-Founder Alexander Harmsen. “The FAA is trusting us to pave the way for a safer, scalable future together with this precedent-setting second approval of our system.”
The U.S. Department of Transportation selected Kansas Department of Transportation as one of nine participants in the FAA UAS IPP. This program allows state, local and tribal governments to conduct advanced UAS operations to gather data to assist the rulemaking process that will set the boundaries for UAS operations in the United States.
FlytBase Inc., an enterprise drone automation company, has launched of FlytGCS, a cloud-based remote drone operations solution, at AUVSI Xponential 2019.

Operators have used FlytGCS in applications ranging from construction management and security/surveillance operations to emergency response and utility/asset inspections.”
The Ohio Unmanned Aircraft Systems Center and the Air Force Research Laboratory (AFRL) will soon begin testing groundbreaking aviation technology at the Springfield-Beckley Municipal Airport.
Ohio Governor Mike DeWine, Lt. Governor Jon Husted and Major General William Cooley, commander of the Air Force Research Laboratory (AFRL) made the announcement April 26 at Wright Patterson Air Force Base.
Skyvision was developed in a collaboration between AFRL and the State of Ohio. AFRL and a delegation of Ohio UAS industry experts will showcase the SkyVision system at AUVSI Xponential in Chicago April 30 to May 2 (Booth 4226).
The SkyVision technology safely, accurately and effectively allows drones to detect and avoid other aircraft while in flight. SkyVision can be described as an air traffic control system for drones.

The validation of this aviation technology led the FAA to grant AFRL a certificate of authorization to test defense-related drone technology without reliance on a visual observer or chase aircraft.
Typically, drones can only fly within the uninterrupted line of sight of the person operating the UAS, but this special waiver allows AFRL and the Ohio UAS Center, which is part of the Ohio Department of Transportation’s DriveOhio Initiative, to use SkyVision to test drones beyond the visual line of sight (BVLOS) within a 200-square-mile parcel of unrestricted airspace near the Springfield-Beckley Municipal Airport.
“As our country steps more and more into the unmanned age of flight, this technology is on the forefront of the aviation frontier, making Ohio a critical national asset for the research and development of UAS technology,” said Governor DeWine. “This also opens the door for commercial companies to work with Ohio, AFRL, and the FAA to test their own UAS-related
technology using our SkyVision detection system. This is a major step in revolutionizing the transportation industry, with Ohio leading the way in aerospace, defense, and aviation innovation.”
“This is an important development in the progression of unmanned aircraft,” said Major General William Cooley, Commander of AFRL at Wright-Patterson Air Force Base. “This waiver provides the latitude to test beyond-line-of-sight keeping AFRL on the leading edge of world-class research and accelerates the delivery of technology that makes a difference to the warfighter.”
“By enabling our lower-altitude airspace for advanced modes of transportation, we’ll be able to facilitate new opportunities around advanced autonomous aircraft research and development,” said Lt. Governor Husted. “This will bring investment to Ohio and solidifies Ohio’s position as a world- recognized leader in aviation technology.”
Ohio’s SkyVision detection system could potentially be used by the state to develop and test UAS technology to assist citizens in the event of a natural disaster or to significantly enhance the capability of search and rescue teams to find missing persons in time-critical situations. Commercial companies, such as those looking to use drones to survey damaged infrastructure or hoping to launch drone commerce operations, will also now have incentive to move to Ohio to test their own UAS technology.
VyrtX, a company based out of Dayton, is among the first companies that has committed to expand into Springfield to work with AFRL and the Ohio UAS Center. VyrtX is currently developing technology for the potential transport of organ donations between hospitals for transplant surgeries.
UAS test flights will take place at heights ranging from 1,000 feet above ground to 10,000 feet mean sea level. Air traffic control experts from the Ohio UAS Center will operate SkyVision during each flight. The SkyVision detection system is located within a mobile unit so that it can be flexibly placed in optimum positions for each flight.
“Today’s announcement comes after years of hard work and collaboration among an incredible group of partners,” said Jeff Hoagland, President and CEO of the Dayton Development Coalition. “AFRL and Ohio had a bold vision to bring UAS into the national airspace for true beyond-visual- line-of-sight flight. The work done here will shape the industry for years to come.”
The State of Ohio and AFRL both invested a combined $5 million for the research and development of SkyVision.
Supported by the Ohio Department of Transportation, DriveOhio works to ensure Ohio’s regulatory environment and public policies are conducive to the development of the infrastructure and technologies needed for smart mobility.
Grand Sky Business and Aviation Park and Harris Corp. have joined forces to enable the country’s first and largest unmanned aerial system (UAS) airspace to support beyond visual line of sight (BVLOS) flight operations and UAS Traffic Management (UTM) research.
Stretching up to 100 miles, this BVLOS “super corridor” is the most technologically sophisticated UAS airspace supported by multiple and redundant systems for cooperative and non-cooperative surveillance.
These surveillance capabilities make possible a wide range of UAS BVLOS applications in precision farming, oil and gas, infrastructure inspection, public safety, package deliveries, and others.
“Customers of Grand Sky will have access to a truly unique UAS operational capability, in addition to better facilities, comprehensive airspace surveillance, and wide operational areas,” Grand Sky Development Co. President Thomas Swoyer Jr., said. “We all benefit from efficient and safe BVLOS flight operations and a larger corridor with proven FAA collaboration and flight authorizations.”
The surveillance system combines data feeds from a network of advanced sensors and towers. Two long-range primary radars located at Grand Forks Air Force Base and at Hillsboro, North Dakota, provide detection of non-cooperative aircraft.
The Federal Aviation Administration (FAA) secondary radars and ADS-B network in the region, as well as local Harris ADS-B Xtend sensors, add additional layers of visibility for cooperative aircrafts in the airspace.
Aviation-grade displays help pilots and electronic observers monitor the airspace environment over the BVLOS corridor and safely steer UAS from approaching manned aircraft.
The combination of best practices in aviation safety management, proven technologies and experience with BVLOS regulatory approvals will make it easy for users of the airspace to advance UAS technology commercialization and routine, efficient flight operations.
UAS operators can work with Grand Sky and Harris to develop, test, and refine a variety of complex BVLOS concepts of operations and secure waivers from the FAA for large-scale use.
A full range of UAS operations can be supported for all types and sizes of unmanned aerial vehicles along the BVLOS corridor including a variety of airspace classes and execution of diverse defense, civil and commercial applications.
“This is another first for Grand Sky and North Dakota in leading the UAS Industry,” Harris Vice President and General Manager of Commercial UAS Solutions George Kirov said. “The size and complexity of the airspace opened to UAS BVLOS operations is unmatched in the UAS industry. The sophistication of the Harris BVLOS system at Grand Sky is also unprecedented — linking Harris’ most advanced suite of surveillance and detect-and-avoid services with a variety of surveillance assets that, together, ensure the highest level of UAS aviation safety.”
This partnership lays the foundation for larger and more capable surveillance corridors to enable UAS “highways” across the state of North Dakota and in support of expanding the variety of commercial UAS operations across the United States.
Few commercial UAV operations would be able to inspect transmissions lines, pipelines or train tracks without beyond visual line-of-sight (BVLOS) capability, but these key pieces of infrastructure often situate close to or transit across population centers. Further, many population centers have airports and low-level air traffic. Any tools to keep drones away from air traffic during BVLOS operations will significantly inspection companies. We review three promising solutions here.
Pipeline Inspection
Kongsberg Geospatial in Ottawa, Canada has developed location visualization software tools that are used for air-traffic control, command and control, and air defense applications. The company has several decades of experience in these applications. Its IRIS software was used to support recent UAV oil pipeline inspection operations in Nigeria, providing safety critical airspace deconfliction, supervised by the Nigerian Civil Aviation Authority (NCAA).
The pipeline project was undertaken by Aerial Robotix, a UAS services provider in Nigeria, who used adapted Kongsberg software in its control center to demonstrate safe BVLOS operations, and was then able to obtain the necessary permits. A Schiebel Camcopter S-100 UAV with a 200-kilometer BVLOS capability was used for flight inspection, operating both day and night, with real time high-definition payload imagery sent back to the control station.

Nigeria has a major problem with gasoline theft from pipelines similar to those lines inspected during this project. Recently, 105 people perished in a blast from a ruptured pipe 30 miles north of the city of Umuahia, possibly during scavenging for leaking fuel. It has been claimed that the pipeline had been ruptured by saboteurs earlier, and for the following six weeks villagers had been collecting fuel. Pipeline vandalism is common in Nigeria, even given the risk of fire or explosion, or the risk of prosecution, or even the possibility of being shot on sight.
Unmanned Companion Fighter Aircraft
Boeing just unveiled a concept UAV which is apparently aimed at providing an airborne team-partner for manned aircraft.The concept was introduced at the Australian International Airshow by the Australian Minister for Defense, the Hon. Christopher Pyne MP. The project is slated for a significant R&D investment by the Australian Government and Boeing Australia.

The concept model has fighter aircraft lines with a projected 2,000-mile range, autonomous capability, and significant intelligence, surveillance and reconnaissance sensor capability. Flying alongside manned fighter/attack aircraft with artificial intelligence simplifying control, the Airpower Teaming System is designed as a low-cost force multiplier.
The concept includes a pitch for international collaboration offering significant customization so countries can add local content, a key element for any aircraft program designed for off-shore sales.

A day or so after the Airshow (maybe not wanting to be upstaged by Boeing’s announcement?) a release showed up about the first flight of the previously secret XQ-58A Valkyrie demonstrator. This is apparently a program by the US Air Force Research Laboratory (AFRL) partnered with Kratos Unmanned Aerial Systems to develop a UAS which looks to have very similar capabilities to that of the Boeing concept, perhaps at a significantly further advanced stage, with a much more mil-spec UAV sounding name.
The AFRL indicated that the XQ-58A is part of a Low Cost Attritable Aircraft Technology (LCAAT) (guess that means they don’t much mind losing a few) effort to come up with low-cost force multipliers which can be built quickly using commercial technology and operating from unprepared runways.
(From the Air Force: “The thought is to develop an inexpensive, configurable and producible on demand air vehicle. A number of military applications can be envisioned for an air vehicle with such a capability. One potential application is to use hundreds or thousands of such units in a campaign to overwhelm an enemy’s air defenses and “punch a hole” to enable higher value, less replaceable [aircraft] to engage or monitor enemy systems. Another potential application is to augment the capabilities of high-value intelligence, surveillance and reconnaissance, systems which may be limited in a specific campaign by distances, quantities, or threats. For all applications, the weapon system is expected to be an air vehicle that would return to base or to a separate location to be recovered. However, because of the mission and because of the low cost, the air vehicle would be attritable, meaning the Air Force would expect and could afford to lose many of the assets.”)
The current program took 2½ years to get to this flying prototype, which still seems pretty lengthy in terms of today’s commercial UAVs. The first flight from Yuma Proving Grounds in Arizona lasted an hour and a quarter and all went as expected. Five test flights are planned to check out functionality, aerodynamics, and launch and recovery systems. Kratos is perhaps better known for its family of target drones which have been in use by the US and internationally for some time.

Kratos Defense & Security Solutions, Inc. announced in early March that its BQM-177A Subsonic Aerial Target (SSAT) has achieved Initial Operational Capability as reported by the US Navy. A Navy statement said “The first site the BQM-177A will be operated from is Pt Mugu, California. The target is capable of speeds in excess of 0.9 Mach and a sea-skimming altitude as low as 10 feet which provides sea-skimming anti-ship cruise missile threat emulation for the US Navy.”
Parachute System for DJI Phantom 4
Recent testing of the descent rate of a Phantom 4 equipped with a SafeAir parachute system indicated that this UAV/parachute combination may well meet the FAA’s recently published draft rules for flight over people. The parachute system uses on-board indicators to trigger parachute deployment. ParaZero (manufacturer of the SafeAir UAV parachute system) has developed standards, and promises to provide customers with certification data to support waiver applications for flight over people.
Wrap-up
So now we have intuitive software using terrain data and sensor inputs which can provide a visual overlay to supports BVLOS flights, concepts designs and prototypes to support the ‘Loyal Wingman’ approach – flying UAVs alongside existing defense aircraft as force multipliers – and advances towards UAV flight over people using certified parachute safety systems. Just a flavor of the flurry of recent new developments in the world of unmanned aircraft.
In Halle, Germany, Microdrones worked with construction company Strabag to fly the mdMapper1000DG above Highway A33 to create a point cloud and orthophoto of a 12-kilometer stretch of the Autobahn.
The drone was equipped with special transponders to make it visible to German Air Traffic Control, enabling beyond-visual-line-of-sight (BVLOS) flight. BVLOS allows for longer flights that cover more area and capture more data.
Using the drone for corridor mapping of the Autobahn enables closer inspection and visualization of the highway to find pavement imperfections, road wear and tear, and other potential safety hazards, Microdrones said.
Drone Rescue will present its parachute systems DRS-5 and DRS-10 to the professional public for the first time at Intergeo, at stand 12.0B.112 in Hall 12, Oct. 16-18.
Parachute rescue system DRS-5 is designed for multicopters with a total weight of up to 8 kg. The system consists of a carbon cage in which the parachute is stored, as well as the associated electronics.
The electronics, including the sensors, monitor the flight status of a drone independent of the flight controller. A sophisticated algorithm merges this sensor data, through which an automatic crash detection can be realized, the company said. In an emergency, the pilot no longer needs to react and press an eject button. (Often, this is technically no longer possible anyway, such as with a failure of the radio link.)
Furthermore, the algorithm reacts faster than the pilot: the system ejects the parachute itself. All flight data and movements are recorded in a black box. In an emergency, these can be read out at the request of the customer and made available to insurance companies or authorities.
“Our goal is to ensure that even in an emergency beyond visual line of sight the drone can be safely intercepted. With our parachute system, that is always possible, due to the electronics that are completely separate and independent of the flight controller,” said Andreas Ploier, CEO and co-founder of Drone Rescue. “In addition, our system has the advantage that it manages completely without explosive, pyrotechnical solutions. Consequently we have a system that is considerably lighter, and functions even in a worst-case scenario.”

The reliability of the system has been verified in extensive tests by Joanneum Aeronautics in Graz, Austria. In the framework of the tests, 100 flights were conducted during which the parachute system was ejected.
Half of the flights were conducted with a DJI F550 weighing 1.6 kg. The rest of the tests were performed with the 3.8 kg Vulture, which was developed by the FH Joanneum.
In both cases, the DRS-5 was attached to the side of the main body of the drone. In each of the tests the parachute was ejected at a height of 30 meters. Every test was documented.
Furthermore, the data were saved both in the flight controller as well as in the DRS-5 sensor system. After every 10th test, the parachute system was subjected to a visual examination and checked for possible damage or wear.
“After conclusion of the tests, it can be recorded that all 100 flights were successfully completed,” Ploier said. “In every test the multicopter landed safely. Thereby, the kinetic energy was significantly below the limit of 79 J. All requirements specified by the European Aviation Safety Agency (EASA) were observed.”
Besides the DRS-5, the structurally identical parachute system DRS-10, which is designed for multicopters with a total weight between 5 and 20 kg, will also be presented at Intergeo 2018. “The DRS-10 system functions exactly the same as the DRS-5 and falls back on the same components. These are constructed identically, just oriented for a higher payload. The functioning method of both parachute systems is identical,” Ploier said.
With flight tests for the DRS-5 completed in late summer, the first systems will be delivered to end customers in winter 2018.

With a small footprint and a strong, bolt-mount aluminum base, the Multimax FV family provides protection against natural hazards threatening vehicles, including vibration, ice, salt, car washes and tree sweeps. The high-gain antennas deliver a large cellular footprint alongside high-rejection GNSS technology (GPS, GLONASS, Galileo and BeiDou).
For Beyond Visual Line-of-Sight (BVLOS) flight operations
Arctic UAV has adopted Kongsberg Geospatial’s IRIS UAS Airspace Awareness application for BVLOS operations within Canada’s Arctic. IRIS provides simultaneous monitoring of multiple drones. It offers real-time calculation of aircraft separation and communications line-of-sight, real-time visualization of track and weather data.
M.A.D.S detects and identifies commercial drones within a 5+ kilometer range, providing GPS positioning of both drone and pilot together with the drone’s speed and heading. Once a drone threat is established, the system enables a 500-meter electronic exclusion zone to be created around the yacht. Should the drone approach this exclusion zone, its control/video signal is blocked, initiating a fail-safe mode and forcing a landing or return to operator.

The Esri book GIS for Surface Water: Using the National Hydrography Dataset by Jeff Simley details how to use geographic information system (GIS) technology to visualize and analyze data sets. Simley is an award-winning cartographer and the former lead of the hydrography program at the United States Geological Survey (USGS). The book examines the complexities of surface water systems and shows readers how to use the Esri ArcGIS software with government water data sets to better study and manage the United States’ vast water system.
EOMAP has opened a commercial online store for global shallow-water bathymetry derived from satellite data. At the store, EOStore Bathymetry, customers can search for and request high-quality data. Satellite-derived bathymetry (SDB) is a valuable tool for the surveying, planning and management of coastal and offshore sites. SDB can provide shallow-water bathymetric data worldwide without the need for a physical presence in the area of interest. EOMAP developed the bathymetry store in response to industry feedback. EOStore Bathymetry offers different horizontal spatial resolutions of the bathymetric grid of 2 to 15 meters, making the data suitable for surveying as well as planning and modeling purposes.
The UX11 is a lightweight, beyond-visual-line-of-sight (BVLOS)-ready fixed-wing mapping drone.
The combination of on-board processing capabilities, real-time control and centimeter-level precision make it a cost-effective solution for large area surveying and mapping, Delair said.

By employing the latest high-specification photographic, sensor and communications elements, Delair has kept the weight of the UX11 — including payload — down to 1.4 kilograms (3.1 pounds). Among other design innovations, this allows the UX11 to cover 200 hectares (500 acres) in a single one-hour flight, delivering mapping with ground sample distances below 1 centimeter per pixel (0.4 in/px) with accuracy down to 1.27 cm (0.5 in).
A 3G/4G network link to the UX11 allows the operator to assess in real time the quality and overlap of images during flight and make any necessary adjustments to the settings of the integrated camera. This enables operators to collect as much aerial intelligence as possible in a minimum number of flights.
The UAV also features BTOL (bird-like take-off and landing) for steep-climb take offs and descents in confined areas.
The AsteRx-m2 delivers high-precision multi-frequency quad-constellation GNSS measurements for PPK (post-processed kinematic) for only 28 grams, and consumes very little power.
The combination of high-quality camera images and GNSS measurements from the AsteRx-m2 allows Delair to offer its users PPK survey-grade ground precision down to 1 centimeter. With Delair’s PPK software, powered by Septentrio’s GeoTagZ PPK library, users only pay for the precision they need and on a flexible pay-as-you-go basis.
“With the AsteRx-m2, we can offer wide-area coverage at ultra-high precision,” said Chase Fly, geospatial product manager at Delair. “The Delair UX11 sets a new standard of efficiency, cost and quality in a long-range UAV platform. The drone itself is truly state-of-the-art in its design and construction, and it enables industry-leading performance and flight range, as well as streamlined maintenance, advantages that all reduce costs.
“The integrated processing capabilities are able to ensure image quality in real time and provide users with accurate results that shape critical operational decisions and strategies,” Fly said. “And it’s designed for flexible use in a variety of conditions and use models, further lowering TCO.”
The AsteRx-m2 features Septentrio’s proprietary GNSS+ suite of positioning algorithms to convert difficult environments into good positioning:
LOCK+ technology to maintain tracking during the heavy dynamic vibration typical of UAV flights
APME+ to combat multipath
IONO+ technology to ensure position accuracy during periods of elevated ionospheric activity.
The AsteRx-m2 also features AIM+ interference mitigation and monitoring system that can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers.
AIM+ can diagnose self-interference from other electrical or electronic devices onboard the UAV as well as mitigating external interference during operational flights.
“Driven by the explosion in the number and variety of drone applications, drone technology has advanced leaps and bounds in recent years and Delair have been right at the heart of the action. With their focus on innovation and a commitment to providing the very highest quality products, Delair and Septentrio are true kindred spirits and we’re proud to be part of the UX11 project,” said Gustavo Lopez, product manager at Septentrio.
