The Air Force Research Laboratory (AFRL) and SpaceWERX, the innovation arm of the U.S. Space Force and a division within AFWERX, have partnered to streamline the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) processes. Their efforts focus on accelerating proposal-to-award timelines, expanding opportunities for small businesses and reducing bureaucratic overhead through continuous process improvements.

In 2018, the DAF introduced the Open Topic SBIR/STTR program to broaden its funds’ range of innovations. This initiative has paved the way for companies like TrustPoint to develop innovative capabilities contributing to national defense.

TrustPoint is developing a commercial GPS service using a C-Band low-earth orbit (LEO) satellite constellation. The system is designed to offer the high performance, security and availability required for autonomous navigation, critical infrastructure and national security.

Little is currently known about the AFRL/GA-ASI unmanned aircraft, other than indications that it has been developed under a Collaborative Combat Aircraft (CCA) program and built on a common frame, which is intended to aid the rapid development of future new variants.

AFRL has previously sponsored Kratos to develop the XQ-58A Valkyrie, which is also intended to “work in teams with manned aircraft,” as a low-cost “attributable” asset commanded by a manned flying companion. The aircraft launches by rocket assist and is recovered vertically by parachute – the new ‘trolley’ launch capability allows the jet-powered Valkyrie to take off on a regular runway.

In earlier flight testing, communications between Valkyrie and both an F-22 Raptor and an F-35 Lightening front-line manned aircraft were established, demonstrating the manned/unmanned teaming concept. With a range of roughly 3,000 mi and an operational ceiling of 44,000 ft, the Valkyrie is intended to demonstrate how an armed, low-cost UAV can bring significant additional assets into combat situations. However, the original test article is now retired and has been put on display at the National Museum of the USAF in Dayton, Ohio, so its demonstration days appear to be over.

Nevertheless, Kratos has built several other production Valkyrie UAVs, which are reportedly undergoing tests with the US Airforce, Marines and Navy. Reports indicate that an XQ-58B electronics defense suppression version has been developed and demonstrated, along with other aircraft that have demonstrated weapons release from an internal stores bay, along with an intriguing release of a small UAV from that same internal bay.

Boeing’s Aurora Flight Sciences has just launched the Skiron-XLE Class 2 UAV – Class 2 meaning that it’s small enough to fit in the back of a pick-up truck. It was derived from an earlier Skiron-X version, which had a wingspan of 16 ft, a length of 7 ft, a weight of less than 50 lb and a meager range of only 8 mi.

Aurora has now come up with a way to extend the range of the vertical take-off and landing (VTOL) UAV by up to 47 miles and increase endurance from 3 hours to more than 5 hours. This was made possible by replacing the original battery power source on the Skiron-X with a compact hydrogen fuel-cell on the XLE supplied by Intelligent Energy (IE). The Skiron-XLE can be equipped with a gimbal mount electro-optic infrared (EO/IR) sensor and is aimed at the military/security reconnaissance role.

When fuel-cells are mentioned, some people may still think of the liquid oxygen/hydrogen sphere that blew up Apollo 13. Fortunately, however, technology has moved on significantly since this less commercial design of the 1960s. As an example, according to the company’s spec sheet, the Department of Transportation (DOT) certified IE-Soar-800W fuel-cell and hydrogen regulator offers 400 w for up to 5.9 hours. Hydrogen/oxygen gasses are combined across two semi-permeable membranes to generate power — no frozen gas-slush stirring is required.

Meanwhile, progress towards eVTOL air-taxi capability took a step forward for Archer and its Midnight aircraft. Stellantis has invested an additional $55 million into Archer’s efforts to build production capacity for up to 650 aircraft per year at its planned 350,000 sq ft facility in Georgia, scheduled to be completed in 2024.

To clarify Stellantis’ background – the company includes manufacturers Fiat-Chrysler and Peugeot, which have merged to form the fourth largest vehicle company by sales behind Toyota, Volkswagen and Hyundai. Stellantis has a strategic funding agreement with Archer and the latest investment follows the milestone first test flight of Midnight where the successful transition from vertical lift to forward flight was achieved. The European conglomerate has also acquired up to $110 million in Archer shares on the open market and through this funding initiative.

Stellantis is working with Archer to bring its manufacturing expertise to the fabrication of Archer’s composite air taxi. High-volume car manufacturing and eVTOL building have a lot in common, and there is clearly common interest for a giant car company to gain access to the new eVTOL market.

To recap – GA-ASI has joined the CCA team with the first flight of the AFRL X-67A unmanned UAV, while Kratos continues with further testing of the Valkyrie CCA UAV with several U.S. forces. The latest generation of hydrogen fuel-cells is now extending the range and endurance of Aurora’s Skiron-XLE, while more investment flows in the eVTOL air taxi market.

The U.S. Air Force Research Laboratory (AFRL) and RTX, formerly Raytheon, have successfully completed a three-week field test of the CHIMERA high-power microwave (HPM) weapon at White Sands Missile Range in New Mexico. During the test, CHIMERA applied directed energy to multiple static target variations and demonstrated end-to-end fire control by acquiring and tracking UAVs and maintaining tracking for the entire flight path.

The Counter-Electronic High-Power Microwave Extended-Range Air Base Defense system, known as CHIMERA, was built to fire highly concentrated radio energy at multiple middle-to-long-range targets. The ground-based demonstration system wields more power than other HPM systems to defeat airborne threats at the speed of light, according to Raytheon.

CHIMERA is part of the Directed Energy Front-line Electromagnetic Neutralization and Defeat (DEFEND) program, which is a joint service effort to design, build and test HPM systems for front-line deployment. Raytheon is partnering with experts at the AFRL, Naval Surface Warfare Center Dahlgren Division, and the Undersecretary of Defense for Research and Engineering to complete this project.

The Navigation Technology Satellite-3 (NTS-3) Vanguard program has reached a milestone in preparation for launch of the satellite in late 2023. NTS-3 is expected to push the boundary of positioning, navigation and timing (PNT) technology, paving the way for a more flexible, robust and resilient architecture for satellite navigation.

Prime contractor L3Harris Technologies delivered the NTS-3 space vehicle to an Air Force Research Laboratory (AFRL) integration and test facility at Kirtland Air Force Base, New Mexico. The satellite integrates an agile PNT payload with a Northrop Grumman ESPAStar bus to provide a space platform for AFRL and partner organization experiments and integrated capability demonstrations.

In 2019, the U.S. Air Force designated NTS-3 one of the first three Vanguard programs to deliver innovative, game-changing capabilities to the warfighter at an accelerated pace. NTS-3 is managed by the AFRL Transformational Capabilities Office and has program partners in both the U.S. Space Force and the U.S. Air Force.

“This major milestone marks the transition from space system development at contractor’s facilities to the final stage of integration and test activities,” said Arlen Biersgreen, NTS-3 program manager. “The AFRL team will be overseeing and working closely with L3Harris and other key industry partners to apply an effective combination of contractor and government resources to successfully complete this phase of the effort.”

AFRL and L3Harris are now completing the remaining intra-payload and payload-to-bus functional and performance tests, including the first radio frequency broadcast tests of the novel PNT signals that will be demonstrated from near-geosynchronous orbit after the NTS-3 launch.

Following those activities, the team will perform standard space environment tests that simulate the launch and space environments to verify that the system is ready for the rigors of experimental operations in space. Biersgreen added that experimental performance data from ground testing will be available for sharing with program partners in the next several months.

The Global Navigation Satellite System Test Architecture, or GNSSTA, developed by the Mitre Corporation in partnership with the AFRL Sensors Directorate, is crucial for meeting end-to-end NTS-3 mission objectives. GNSSTA is a reprogrammable software-defined receiver allowing users to receive both legacy GPS and advanced signals generated by NTS-3. It lays the groundwork for future operational receivers to provide the Space Force with options to prevent and respond quickly to common threats on the battlefield, such as GPS jamming and spoofing.

Joanna Hinks, NTS-3 principal investigator, worked closely with the Sensors team on GNSSTA development and testing. “The entire team is excited that earlier this month, we successfully generated signals on the actual spacecraft and received them with our experimental GNSSTA user equipment,” Hinks said. “Showing the space segment and user segment working together like that is an important step to being ready to conduct experiments on-orbit.”

NTS-3 is the first U.S. experiment of its kind in nearly 50 years, since the Navy Research Laboratory’s NTS-1 and NTS-2 spacecraft led the way for the GPS constellation in the 1970s.

“This Vanguard not only aims to support GPS users through vital development of new technologies and techniques, but also to show how an agile and responsive U.S. satellite navigation architecture is paramount to defeating the most challenging threats to warfighter success, both today and through the coming decades,” Biersgreen said.

“We’re really excited to push the state of the art with more than 100 experiments on this little [NTS-3] spacecraft and we’re looking at ways that we can solve warfighters’ problems in the contested environment,” Maj. Gen. Heather Pringle, commander of AFRL, told reporters April 6 at the 37th Space Symposium in Colorado Springs.

Set to launch in 2023, NTS-3 is designed to push the boundary of today’s position, navigation and timing (PNT) technology to pave the way for a more flexible, robust, and resilient architecture for satellite navigation technology.

NTS-3 is a product of the Air Force Research Laboratory (AFRL) and industry, designed to test advanced techniques and technologies to detect and mitigate interference to PNT capabilities and increase system resiliency for military, civil, and commercial users.

Unlike the GPS medium-Earth-orbit satellites, NTS-3 will operate for one year in geosynchronous Earth orbit. Ultimately, NTS-3 will identify key aspects for new GPS receivers that incorporate multiple signals and readily adapt to warfighter needs.

The NTS-3 experiments will also involve ground equipment and terminals such as command and control stations and software-defined radios. Specific improvements to the ground segment will enable experimentation with automated “lights-out” operations, control station failover, and near-real time environment sensing and generation of error correction and tailored waveforms. Onboard systems will monitor clock accuracy and orbit parameters to mitigate errors and notify the user.

NTS-3 will test a new digital signal generator that can be reprogrammed on-orbit, enabling it to broadcast new signals, improve performance by avoiding and defeating interference, and adding signatures to counter spoofing.

AFRL also will explore antenna configurations to provide Earth coverage and steerable regional beams in multiple frequencies and signal codes. The NTS-3 satellite will be equipped with 110 antennas to help counter attempted GPS jamming.

Ultimately, NTS-3 is expected to provide users with enhanced signal stability, availability, integrity and accuracy.

L3Harris plans to deliver NTS-3 later this year. The company is assembling the satellite at its Palm Bay facility near Cape Canaveral, Florida. The plant was expanded in 2021 to accommodate the NTS-3 program.

The Air Force Research Laboratory’s complementary positioning, navigation and timing (PNT) AgilePod prototype achieved three important objectives in flight tests conducted at Edwards Air Force Base Nov. 1-10, 2021.

PNT AgilePod helps develop advanced navigation technology independent of GPS, according to Maj. Andrew Cottle, Air Force Strategic Development Planning and Experimentation (SDPE) office. This technology provides reliable, resilient PNT navigation signals through alternative means, increasing mission effectiveness in scenarios where access to GPS is not guaranteed.

The test team — representing a broad base of Air Force, Navy and vendor organizations — successfully executed eight sorties aboard a T-38C aircraft, which included:

• the first test of the PNT AgilePod on a high-dynamic-range platform
• the first test of fully remote interfacing and alt-PNT data transmission
• the first demonstration of overland/overwater transition performance.

He said the tests demonstrated the operational utility of a fused alt-PNT system incorporating multiple technologies within a single government-owned open-architecture prototype.

AgilePods Designed for Flexibility

AgilePods are comprised of a series of compartments and can be configured to meet a wide variety of mission requirements for many aircraft platforms. Experimenters can fill the spaces with plug-and-play sensors they need for a mission — high-definition video, electro-optical and infrared sensors, and devices with other capabilities — including PNT.

The AgilePod has an open hardware architecture. For the complementary PNT prototype, it was combined with an open software architecture that allows a wide variety of alternative PNT technology to integrate and pass information. These capabilities enable rapid integration of sensor technologies through standardized software and hardware interfaces, allowing the pod to seamlessly integrate on platforms that leverage the standard architectures.

In this way, one pod can perform hundreds of different mission sets with additional benefits of cost savings and increased sustainability, Cottle said.

The project directly supports the AFRL PNT Enterprise and the Air Force PNT Cross-Functional Team as they work to ensure reliable navigation within GPS-contested operational scenarios critical to the success of future Air and Space Force missions.

The NTS-3 experimental satellite will be launched in 2023, according to reports from C4ISRNET and Space News. The United States military will use the satellite for positioning, navigation and timing (PNT) as a supplement to GPS.

The satellite was originally set to launch in 2022.

The Air Force Research Laboratory (AFRL) plans to use the additional time to reduce risks and conduct more ground testing.

Navigation Technology Satellite 3 will help guide future GPS satellites, a priority area for the military as the technology has become easier to spoof and jam. Among other features, NTS-3 will have steerable beams for regional coverage and a software-defined payload that can be reprogrammed on orbit.

AFRL discussed the delay in a media roundtable held Wednesday, reports C4ISRNET. AFRL Commander Brig. Gen. Heather Pringle said that shift was out of the lab’s control since the satellite will launch as a rideshare with a U.S. Space Force payload, and that launch had been pushed back.

AFRL plans to experiment with the satellite in geosynchronous orbit for one year, testing PNT signals and architectures as well as ground-based command and control systems and software-defined radios. Following testing, NTS-3 will transition to the U.S. Space Force and integrate into the service’s other PNT capabilities.

In February 2020, L3Harris Technologies passed the NTS-3 project’s preliminary design review. L3Harris is the project’s prime contractor.
