27 Jul 22. UAV Navigation’s Flight Control System Integrates Advanced Detect & Avoid capabilities. UAV Navigation has recently enhanced its long-term collaboration with both Sagetech Avionics, Inc. and Iris Automation for the integration of transponders and real-time computer vision to improve the sense and avoid capabilities of its flight control solutions.
Sagetech’s MX family of transponders and Iris Automation’s innovative detect and avoid Casia systems provide the VECTOR autopilot with the capability to detect uncooperative crewed and uncrewed aircraft in its airspace and autonomously or manually take corrective action, avoiding potential collisions.
Transponders are devices that transmit position and attitude parameters from an aircraft in flight to a local control tower or compatible receiver. Sagetech’s FAA Certified ADS-B IN/OUT transponder feeds the UAV Navigation flight control system with real-time information about a suitably equipped aircraft in flight so that it can be displayed directly within Visionair, the ground control station software.
Iris Automation’s Casia computer vision systems leverage AI and deep learning algorithms to detect surrounding air traffic, , facilitating automated or manual deconfliction and the prevention of collisions.
These integrations enhance the operational safety of aircraft using UAV Navigation’s system and create a benchmark for the detection and avoidance of cooperative and non-cooperative air traffic in the UAV sector.
UAV Navigation is keenly aware that one of the most significant challenges facing the aviation industry is the coexistence of numerous crewed and uncrewed platforms within a single airspace. This collaboration enables direct compatibility with the products from the three companies and allows straightforward integration within a single, intuitive interface from which the UAV operator can monitor and control the mission.

27 Jul 22. Innovation With the Additive Advantage. Combining cutting-edge technology with additive manufacturing redefines the limits set within traditional manufacturing and delivers innovation in places you might not expect
While companies across the world rise to the challenges affecting supply chains, a transformation in technology and innovation is shifting the manufacturing paradigm. Additive manufacturing (AM), more commonly known as 3D printing, is an innovative process where objects are created one layer at a time. Shapes and designs that were once thought impossible and too complex are now possible to produce. The range of design is expanded, and its potential is limitless.
Northrop Grumman is reshaping how it approaches design and manufacturing processes, like using 3D printing to support missions in new ways,” said Matt Bromberg, corporate vice president, global operations, Northrop Grumman.
Northrop Grumman has been at the forefront of adopting this compelling design and build method. AM delivers agility, consolidation and savings on lead-times, costs and resources. Products are produced faster and cheaper through its capabilities. Northrop Grumman continues to innovate using AM and has helped facilitate this transformation across several platform-types, ranging from radio frequency sensors, engines, hypersonic weapons and aerospace structures.
3D Printing in Action
From 3D printing rocket motors to using advanced materials to produce aircraft parts, the company uses AM across the enterprise.
Northrop Grumman has also advanced AM applications to space. For NASA’s Artemis I mission, Northrop Grumman designed twin solid rocket boosters to propel the Space Launch System (SLS) rocket. In 2020, Northrop Grumman shipped 10 rocket motor segments from Promontory, Utah, to the Kennedy Space Center, where the motor segments were assembled into two separate solid rocket boosters. The assembly of these boosters relied in part on 3D printing and computer modeling to modify heritage component designs from the shuttle program and to create new components that are compatible with heritage assembly ones in use.
In 2019, Made In Space (MIS) selected Northrop Grumman to support NASA’s Space Technology Mission Directorate (STMD) demonstration of the autonomous robotic manufacturing and assembly platform, Archinaut. The objective of Archinaut’s flight demonstration mission is to construct two 10-meter solar arrays, on orbit, to power a small Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) satellite. Once on orbit, Archinaut will employ its extended structure AM capabilities and advanced robotics to manufacture and assemble the satellite’s power generation system.
“Demonstrating additive manufacturing in space will open up new doors in the design and construction of space structures that to date have been limited by the volume of a launch vehicle,” said Richard Stapp, vice president and chief technology officer, Northrop Grumman. “Effectively building structures in space is one of the next big steps in our continuous journey of space exploration.”
Investing in the Transformation of Manufacturing
Northrop Grumman has invested more than $70 m in AM with more than 5,000 AM parts currently integrated into the company’s aeronautic platforms, all produced by small- and medium-sized suppliers and partners. The company also currently collaborates with several universities and colleges.
In 2019, Northrop Grumman awarded the U.S. Naval Academy (USNA) Foundation a $150,000 grant to support AM in the Academy’s Division of Engineering & Weapons. The grant funded the growth of the USNA MakerSpace, a student-faculty 3D printing laboratory, and its associated engineering programs.
“Advancements in additive manufacturing are enabling the rapid development of next-generation materials and hardware with reduced life-cycle costs and cycle times to give our warfighters the tactical advantage against emerging threats in complex combat environments,” says Larry Ferranto, vice president, maritime/land systems and sensors operations,
27 Jul 22. iXblue, ECA systems demonstrate subsea asset tracking in shallow water. The trials were conducted for Polish Naval Academy and US NAVSUP attendees of current year. iXblue in collaboration with ECA Group have successfully carried out subsea asset tracking demonstration in the shallow waters. The demonstration was conducted for the US Naval Supply Systems Command (NAVSUP) and the Polish Naval Academy’s attendees.
Hosted by a Polish defence sector company THESTA, this demonstration involved iXblue’s Gaps M7 ultra short baseline (USBL) positioning system and ECA Group’s new R7 remotely operated vehicle (ROV).
During the demonstration, R7 ROV was deployed to investigate objects submerged in shallow waters of the Baltic Sea region in Gdynia harbour.
The acoustic positioning system Gaps M7 USBL was responsible for geolocating R7 ROV and correcting its trajectory in real time.
The trials were conducted in 7m to 10m deep waters, surrounded by several docks and vessels causing significant acoustic echoes.
Besides, a fixed transponder that was placed 5m deep and hundreds of meters away from the vessel.
It aimed to showcase that it is possible to locate the precise position of underwater targets in a fast-approaching and potentially hostile environment, in coastal regions with limited access.
THESTA technical director Cezary Majchrowicz said: “The R7 ROV along with Gaps M7 USBL acoustic positioning system is able to transmit information accurately, even in noisy and difficult acoustic environments.
“They both enable fast operation as well as regular and quick position updates, even in very shallow waters, which is a definite asset for the navies, given their need for a fast, clear and concise picture of the battlespace to quickly manoeuvre naval forces in the field.”
According to iXblue, the ROV inspection was successful even in low visibility.
It was possible with the help of HD acoustic inspection camera that provided high-resolution data with superior localisation precision.
