BAE Systems has been awarded funding from the Defense Advanced Research Projects Agency (DARPA) to integrate Machine-Learning (ML) technology into platforms that decipher radio frequency signals. Its Controllable Hardware Integration for Machine-learning Enabled Real-time Adaptivity (CHIMERA) solution provides a reconfigurable hardware platform for ML algorithm developers to make sense of Radio Frequency (RF) signals in increasingly crowded electromagnetic spectrum environments.
The up to $4.7 million contract, dependent on successful completion of milestones, includes hardware delivery along with integration and demonstration support. CHIMERA’s hardware platform will enable algorithm developers to decipher the ever-growing number of RF signals, providing commercial or military users with greater automated situational awareness of their operating environment. This contract is adjacent to the previously announced award for the development of data-driven ML algorithms under the same DARPA program (Radio Frequency Machine Learning Systems, or RFMLS).
RFMLS requires a robust, adaptable hardware solution with a multitude of control surfaces to enable improved discrimination of signals in the evolving dense spectrum environments of the future.
«CHIMERA brings the flexibility of a software solution to hardware», said Dave Logan, vice president and general manager of Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) Systems at BAE Systems. «Machine-learning is on the verge of revolutionizing signals intelligence technology, just as it has in other industries».
In an evolving threat environment, CHIMERA will enable ML software development to adapt the hardware’s RF configuration in real time to optimize mission performance. This capability has never before been available in a hardware solution. The system provides multiple control surfaces for the user, enabling on-the-fly performance trade-offs that can maximize its sensitivity, selectivity, and scalability depending on mission need. The system’s open architecture interfaces allow for third party algorithm development, making the system future-proof and easily upgradable upon deployment.
Other RF functions, including communications, radar, and electronic warfare, also can benefit from this agile hardware platform, which has a reconfigurable array, front-end, full transceiver and digital pre-processing stage. Work on these phases of the program will take place at BAE Systems’ sites in Hudson and Merrimack, New Hampshire, and Dallas, Texas.
A technology kit developed by Sikorsky, a Lockheed Martin company, was used for the first time to operate a Black Hawk helicopter with full-authority, fly-by-wire flight controls. The May 29 flight marked the official start to the flight test program for the soon-to-be optionally piloted aircraft. Follow-on flight testing aims to include envelope expansion throughout the summer leading to fully autonomous flight (zero pilots) in 2020.
«This technology brings a whole new dimension of safety, reliability and capability to existing and future helicopters and to those who depend on them to complete their missions», said Chris Van Buiten, Vice President, Sikorsky Innovations. «We’re excited to be transforming a once mechanically controlled aircraft into one with fly-by-wire controls. This flight demonstrates the next step in making optionally piloted – and optimally piloted – aircraft, a reality».
This is the first full authority fly-by-wire retrofit kit developed by Sikorsky that has completely removed mechanical flight controls from the aircraft.
Through DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program, Sikorsky is developing an OPV approach it describes as pilot directed autonomy to give operators the confidence to fly aircraft safely, reliably and affordably in optimally piloted modes enabling flight with two, one or zero crew. The program aims to improve operator decision aiding for manned operations while also enabling both unmanned and reduced crew operations.
Sikorsky has been demonstrating its MATRIX Technology on a modified S-76B called the Sikorsky Autonomy Research Aircraft (SARA). The aircraft, which has been in test since 2013, has more than 300 hours of autonomous flight.
Sikorsky announced in March that its S-92 helicopter fleet update will include the introduction of phase one MATRIX Technology that will bring advanced computing power to the platform. This foundation enables adoption of autonomous landing technology.
Raytheon Company successfully tested a hot fire rocket motor for DARPA’s Multi-Azimuth Defense Fast Intercept Round Engagement System, or MAD-FIRES.
The MAD-FIRES interceptor is designed to provide a robust and affordable self-defense capability that defeats multiple waves of anti-ship missiles, unmanned aerial vehicles, as well as other threats.
«The Navy is asking for leading-edge capabilities that can take out rapidly approaching targets, and Raytheon’s interceptor for the MAD-FIRES program will deliver», said Doctor Thomas Bussing, Raytheon Advanced Missile Systems vice president. «This test shows Raytheon is right on track to provide an affordable, advanced technology to the fleet».
If fielded, this capability will combine the speed, rapid fire and depth of a gun weapon system with the precision and accuracy of guided missiles.
The Defense Advanced Research Projects Agency (DARPA) Biological Technology Office selected Northrop Grumman Corporation to prototype sensing capabilities using undersea organisms to assist in passively detecting and tracking undersea threats.
As part of the Persistent Aquatic Living Sensors (PALS) program, Northrop Grumman will develop biological sensing hardware that has increased sensitivity for certain sensor modalities, achieving greater range. Artificial intelligence will be applied to observe patterns in the marine environment to help classify targets. Northrop Grumman is partnered with Coda Octopus, Duke University, University of Maryland, Baltimore County and the University of Memphis.
«The detection, classification and tracking of undersea objects is a critical military capability and we are excited to work with DARPA to develop this next generation approach», said Mike Meaney, vice president, advanced missions, Northrop Grumman.
Raytheon Company won a $63.3 million DARPA contract to further develop the Tactical Boost Glide hypersonic weapons program. The joint DARPA and U.S. Air Force effort includes a critical design review, a key step in fielding the technology.
«This latest contract adds to Raytheon’s growing number of hypersonic weapons programs», said Doctor Thomas Bussing, Raytheon Advanced Missile Systems vice president. «Raytheon is working closely with our customers to quickly field these advanced weapon systems and provide our nation’s military with the tools they need to stay ahead of the escalating threat».
Hypersonic weapons will enable the U.S. military to engage from longer ranges with shorter response times and enhanced effectiveness compared to current weapon systems.
Systems that operate at hypersonic speeds – five times the speed of sound (Mach 5) and beyond – offer the potential for military operations from longer ranges with shorter response times and enhanced effectiveness compared to current military systems. Such systems could provide significant payoff for future U.S. offensive strike operations, particularly as adversaries’ capabilities advance.
The Tactical Boost Glide (TBG) program is a joint DARPA/U.S. Air Force (USAF) effort that aims to develop and demonstrate technologies to enable future air-launched, tactical-range hypersonic boost glide systems. In a boost glide system, a rocket accelerates its payload to high speeds. The payload then separates from the rocket and glides unpowered to its destination.
The TBG program plans to focus on three primary objectives:
Vehicle Feasibility – Vehicle concepts possessing the required aerodynamic and aerothermal performance, controllability and robustness for a wide operational envelope;
Effectiveness – System attributes and subsystems required to be effective in relevant operational environments;
Affordability – Approaches to reducing cost and increasing value for both the demonstration system and future operational systems.
TBG is a two-phase effort that plans to include ground and flight testing to mature critical technologies, and aims to demonstrate the system performance achievable through the integration of those technologies. The program is using a disciplined systems engineering approach to define demonstration system objectives and identify enabling technologies needed for future systems. The TBG program is exploiting the technical knowledge and lessons derived from development and flight testing of previous boost glide systems, including the Hypersonic Technology Vehicle 2 (HTV-2).
Airbus Defense and Space Inc. has been awarded a contract from the Defense Advanced Research Projects Agency (DARPA) to develop a satellite bus in support of the Blackjack program.
DARPA describes the Blackjack program as an architecture demonstration intending to show the military utility of global low-earth orbit constellations and mesh networks of lower size, weight and cost. DARPA wants to buy commercial satellite buses and pair them with military sensors and payloads. The bus drives each satellite by generating power, controlling attitude, providing propulsion, transmitting spacecraft telemetry, and providing general payload accommodation including mounting locations for the military sensors.
«Airbus has previously co-invested hundreds of millions of dollars in high-rate manufacturing technology and supply chain logistics to build large constellations of small satellites», said Tim Deaver, Director of U.S. Space Programs at Airbus Defense and Space, Inc. «Airbus is committed to growing manufacturing capability in the U.S. and our government customers can leverage this commercial capability to develop low-earth orbit constellations to complement large existing systems».
This contract positions Airbus Defense and Space, Inc., of Herndon, Virginia, and its strategic joint venture partner, OneWeb Satellites, of Exploration Park, Florida, as the ideal service providers for Blackjack.
High production rates and design-to-cost management techniques enable OneWeb Satellites to offer low cost constellation solutions for the U.S. government and current customers. Constellations of inexpensive satellites permit wide scale disaggregated architectures enhancing survivability across many different mission areas.
OneWeb Satellites is pioneering new value propositions in space. They are leading the design and manufacturing of ultra-high performing satellites at high-volumes.
«We have created a game changer with our overall design, supply chain and production system», said Tony Gingiss, CEO, OneWeb Satellites. «Our team is transforming the space industry and we are in the midst of demonstrating we can deliver on our promises».
OneWeb Satellites brings to bear capabilities which dramatically lower the cost and shorten acquisition timelines for customers thanks to a modular design and agile serial production of satellites.
The OneWeb Satellites satellite manufacturing facility in Florida is the latest step in Airbus’ continued and long-standing commitment to growth in U.S. manufacturing, job creation and investment.
This facility, which will ultimately support thousands of jobs and follows the opening of our U.S. Manufacturing Facility for A320 aircraft in Mobile, Alabama, from which we delivered our first aircraft in 2016. An A220 assembly line on the same site in Alabama will break ground in January of 2019.
With our extensive network of U.S. suppliers, Airbus is the largest consumer of U.S. aerospace and defense goods in the world – buying more than any other company or even country. Airbus invested $16.5 billion with U.S. companies in 2017, supporting 275,000 American jobs.
U.S. Army pilots exercised supervised autonomy to direct an Optionally-Piloted Helicopter (OPV) through a series of missions to demonstrate technology developed by Sikorsky, a Lockheed Martin company and the Defense Advanced Research Projects Agency (DARPA). The series of flights marked the first time that non-Sikorsky pilots operated the Sikorsky Autonomy Research Aircraft (SARA), a modified S-76B commercial helicopter, as an OPV aircraft.
«Future vertical lift aircraft will require robust autonomous and optimally-piloted systems to complete missions and improve safety», said Chris Van Buiten, vice president, Sikorsky Innovations. «We could not be more thrilled to welcome Army aviators to the cockpit to experience first-hand the reliability of optimally-piloted technology developed by the innovative engineers at Sikorsky and DARPA. These aviators experienced the same technology that we are installing and testing on a Black Hawk that will take its first flight over the next several months».
SARA, which has more than 300 hours of autonomous flight, successfully demonstrated the advanced capabilities developed as part of the third phase of DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program. The aircraft was operated at different times by pilots on board and pilots on the ground. Sikorsky’s MATRIX Technology autonomous software and hardware, which is installed on SARA, executed various scenarios including:
Automated Take Off and Landing: The helicopter autonomously executed take-off, traveled to its destination, and autonomously landed;
Obstacle Avoidance: The helicopter’s LIDAR and cameras enabled it to detect and avoid unknown objects such as wires, towers and moving vehicles;
Automatic Landing Zone Selection: The helicopter’s LIDAR sensors determined a safe landing zone;
Contour Flight: The helicopter flew low to the ground and behind trees.
The recent Mission Software Flight Demonstration was a collaboration with the U.S. Army’s Aviation Development Directorate, Sikorsky and DARPA. The Army and DARPA are working with Sikorsky to improve and expand ALIAS capabilities developed as a tailorable autonomy kit for installation in both fixed wing airplanes and helicopters.
Over the next few months, Sikorsky will for the first time fly a Black Hawk equipped with ALIAS. The company is working closely with the Federal Aviation Administration to certify ALIAS/MATRIX technology so that it will be available on current and future commercial and military aircraft.
«We’re demonstrating a certifiable autonomy solution that is going to drastically change the way pilots fly», said Mark Ward, Sikorsky Chief Pilot, Stratford, Conn. Flight Test Center. «We’re confident that MATRIX Technology will allow pilots to focus on their missions. This technology will ultimately decrease instances of the number one cause of helicopter crashes: Controlled Flight Into Terrain (CFIT)».
Through the DARPA ALIAS program, Sikorsky is developing an OPV approach it describes as pilot directed autonomy that will give operators the confidence to fly aircraft safely, reliably and affordably in optimally piloted modes enabling flight with two, one or zero crew. The program will improve operator decision aiding for manned operations while also enabling both unmanned and reduced crew operations.
Northrop Grumman Corporation and the Defense Advanced Research Projects Agency (DARPA) have set a new standard for wireless transmission by operating a data link at 100 gigabits per second (Gbps) over a distance of 20 kilometers/12.4 miles in a city environment.
The two-way data link, which featured active pointing and tracking, was demonstrated January 19, 2018 in Los Angeles.
The blazing data rate is fast enough to download a 50 Gigabyte blue ray video in four seconds. The demonstration marked the successful completion of Northrop Grumman’s Phase 2 contract for DARPA’s 100 Gbps (100G) RF Backbone program.
The 100G system is capable of rate adaptation on a frame by frame basis from 9 Gbps to 102 Gbps to maximize data rate throughout dynamic channel variations. Extensive link characterization demonstrated short-term error-free performance from 9 to 91 Gbps, and a maximum data rate of 102 Gbps with 1 erroneous bit received per ten thousand bits transmitted.
The successful data link results from the integration of several key technologies. The link operates at millimeter wave frequencies (in this case, 71-76 gigahertz and 81-86 gigahertz) with 5 gigahertz of bandwidth, or data carrying capacity, and uses a bandwidth efficient signal modulation technique to transmit 25 Gbps data streams on each 5 gigahertz channel. To double the rate within the fixed bandwidth, the data link transmits dual orthogonally polarized signals from each antenna. Additionally, the link transmits from two antennas simultaneously (spatial multiplexing) and uses Multiple-Input-Multiple-Output (MIMO) signal processing techniques to separate the signals at two receiving antennas, thus again doubling the data rate within the fixed bandwidth.
According to Louis Christen, director, research and technology, Northrop Grumman, «This dramatic improvement in data transmission performance could significantly increase the volume of airborne sensor data that can be gathered and reduce the time needed to exploit sensor data».
«Next generation sensors such as hyperspectral imagers typically collect data faster, and in larger quantity than most air-to-ground data links can comfortably transmit», said Christen. «Without such a high data rate link data would need to be reviewed and analyzed after the aircraft lands».
By contrast, a 100G data link could transmit high-rate data directly from the aircraft to commanders on the ground in near real time, allowing them to respond more quickly to dynamic operations.
The successful 100G ground demonstration sets the stage for the flight test phase of the 100G RF Backbone program. This next phase, which started in June, demonstrates the 100G air-to-ground link up to 100 Gbps over a 100 km/62.1 miles range and extended ranges with lower data rates. The 100G hardware will be flown aboard the Proteus demonstration aircraft developed by Northrop Grumman subsidiary Scaled Composites.
Northrop Grumman’s 100G industry team includes Raytheon, which developed the millimeter wave antennas and related RF electronics and Silvus Technologies, which provides the key spatial multiplexing and MIMO signal processing technologies.
Lockheed Martin Skunk Works and the Defense Advanced Research Projects Agency (DARPA) recently performed a series of flight tests demonstrating how a System of Systems (SoS) approach enables seamless – and rapid – integration across air, space, land, sea and cyber in contested environments.
The demonstrations held at the Naval Air Warfare Center in China Lake, California, were part of a five-year DARPA program called System of Systems Integration Technology and Experimentation (SoSITE). The flight tests demonstrated interoperability between a ground station, flying test bed, a C-12 and flight test aircraft, and proved the ability to transmit data between those systems using STITCHES, a novel integration technology.
The test used the Skunk Works developed Enterprise Open System Architecture Mission Computer version 2 (EMC2), known as the «Einstein Box», as the open computing environment, providing security protections between systems. The Einstein Box enables rapid and secure experimentation before deploying the capability to operational systems. The team successfully demonstrated four key capabilities:
The ability to automatically compose and transmit messages between systems, including those using legacy datalinks;
The first use of Non-Enterprise Data Links to create new, rich information exchanges in-flight through Link-16, enabling greater speed, agility, modernization and effectiveness;
The ability to link ground-based cockpit simulators with live aircraft systems in real time to demonstrate how a SoS approach reduces the data-to-decision timeline;
Integration between the APG-81 radar, currently used on the F-35, and DARPA’s Automatic Target Recognition software to reduce operator workload and to create a comprehensive picture of the battlespace.
Demonstrating rapid and affordable integration of mission systems into existing and new architectures, SoSITE will help U.S. forces maintain their advantage in today’s dynamic world.
«The successful demonstrations focused on advancing integration technologies to increase capabilities of systems in operation today, enabling our warfighters to use those systems in unexpected ways», said Justin Taylor, Lockheed Martin Skunk Works Mission Systems Roadmaps director. «The SoS approach is essential for allowing U.S. forces to rapidly reconfigure systems and prevail over any threat».
The project was led by Lockheed Martin Skunk Works in partnership with the U.S. Air Force and support from industry partners Apogee Research, Northrop Grumman, Lockheed Martin Missiles and Fire Control, BAE Systems, Phoenix Flight Test, General Dynamics and Rockwell Collins.
Skunk Works’ expertise in open system architecture spans more than a decade. The success of SoSITE is a critical step to enabling multi-domain operations and maintaining superiority in the future battlespace. In its 75th year, Lockheed Martin Skunk Works is proud to advance SoS integration in partnership with DARPA as they celebrate 60 years of creating breakthrough technologies and capabilities for national security.
DARPA’s Ground X-Vehicle Technologies (GXV-T) program aims to improve mobility, survivability, safety, and effectiveness of future combat vehicles without piling on armor. Several Phase 2 contract awardees recently demonstrated advances on a variety of potentially groundbreaking technologies to meet the program’s goals.
«We’re looking at how to enhance survivability by buttoning up the cockpit and augmenting the crew through driver-assistance aids», said Major Amber Walker, the program manager for GXV-T in DARPA’s Tactical Technology Office. «For mobility, we’ve taken a radically different approach by avoiding armor and developing options to move quickly and be agile over all terrain».
Demonstrations, such as one in May at Aberdeen Test Center, have given potential military service transition partners an opportunity to observe technical progress on the GXV-T program, including:
Radically Enhanced Mobility
GXV-T envisions future combat vehicles that could traverse up to 95 percent of off-road terrain, including slopes and various elevations. Capabilities include revolutionary wheel-to-track and suspension technologies that would enable access and faster travel both on- and off-road, compared to existing ground vehicles.
Reconfigurable Wheel-Track (RWT)
Wheels permit fast travel on hard surfaces while tracks perform better on soft surfaces. A team from Carnegie Mellon University National Robotics Engineering Center (CMU NREC) demonstrated shape-shifting wheel-track mechanisms that transition from a round wheel to a triangular track and back again while the vehicle is on the move, for instant improvements to tactical mobility and maneuverability on diverse terrains.
Electric In-hub Motor
Putting motors directly inside the wheels offers numerous potential benefits for combat vehicles, such as heightened acceleration and maneuverability with optimal torque, traction, power, and speed over rough or smooth terrain. In an earlier demonstration, QinetiQ demonstrated a unique approach, incorporating three gear stages and a complex thermal management design into a system small enough to fit a standard military 20-inch/51-cm rim.
Multi-mode Extreme Travel Suspension (METS)
Pratt & Miller’s METS system aims to enable high-speed travel over rough terrain while keeping the vehicle upright and minimizing occupant discomfort. The vehicle demonstrator incorporates standard military 20-inch/51-cm wheels, advanced short-travel suspension of four-to-six inches, and a novel high-travel suspension that extends up to six feet – 42 inches/106.7 cm upward and 30 inches/76.2 cm downward. The demonstration in May showed off its ability to tackle steep slopes and grades by actively and independently adjusting the hydraulic suspension on each wheel of the vehicle.
Traditional combat vehicle designs have small windows that improve protection, but limit visibility. GXV-T sought solutions with multiple onboard sensors and technologies to provide high-resolution, 360-degree situational awareness while keeping the vehicle enclosed.
Enhanced 360-degree Awareness with Virtual Windows
Honeywell International demonstrated its windowless cockpit in an All-Terrain Vehicle (ATV) with an opaque canopy. The 3-D near-to-eye goggles, optical head-tracker and wrap-around Active Window Display screens provide real-time, high-resolution views outside the vehicle. In off-road courses, drivers have completed numerous tests using the system in roughly the same time as drivers in All Terrain Vehicles with full visibility.
A tactical vehicle offers limited visibility and data for decision-making, especially when moving rapidly through unfamiliar territory. Raytheon BBN Technologies’ V-PANE technology demonstrator fuses data from multiple vehicle-mounted video and LiDAR cameras to create a real-time 3-D model of the vehicle and its nearby surroundings. In a final Phase 2 demonstration, drivers and commanders in a windowless recreational vehicle successfully switched among multiple virtual perspectives to accurately maneuver the vehicle and detect targets of interest during both low- and high-speed travel.
Off-Road Crew Augmentation (ORCA)
A second CMU NREC technology demonstration, ORCA aims to predict in real time the safest and fastest route and when necessary, enable a vehicle to drive itself off-road – even around obstacles. In Phase 2 testing, drivers using the ORCA aids and visual overlays traveled faster between waypoints and eliminated nearly all pauses to determine their routes. The team found autonomy improved either vehicle speed or risk posture, and sometimes both.
Walker said GXV-T performers are pursuing a variety of transition paths for the new technologies.
«DARPA’s excited about the progress made to date on the GXV-T program and we look forward to working with the Services to transition these technologies into ground vehicle technologies of the future», said Walker.
DARPA’s Ground X-Vehicle Technologies (GXV-T) program demonstrations show progress on technologies for traveling quickly over varied terrain and improving situational awareness and ease of operation
