The project establishes a certification-aligned, risk-driven cybersecurity foundation for secure, resilient and scalable unmanned traffic management (UTM) and U-space services across Europe. 

As drone operations grow in complexity and cross-border interoperability, cybersecurity is becoming essential for operational continuity and public trust. SecureUTM 2 embeds cybersecurity engineering into the core architecture of UTM systems, aligning with European U-space regulations, Common Criteria methodology and ENISA risk frameworks. Security is treated as a foundational design principle rather than a late-stage compliance requirement. 

Building on SecureUTM 1, SecureUTM 2 Phase I significantly expanded the cybersecurity baseline for UTM systems. Key outcomes include: 

• Refinement of a harmonized Protection Profile (PP) for UTM 
• Development of an updated Security Target (ST) for the Unifly platform 
• Structured risk assessment and certification-aligned gap analysis 
• Definition of a secure architectural baseline addressing real-world U-space complexity 
• Setup of a PoC Testbed 

Risk-based engineering roadmap

A control-by-control gap assessment translated cybersecurity requirements into a prioritised implementation roadmap. Focus areas include: 

• PNT source authentication and plausibility checks 
• Enhanced session integrity and transport protection 
• Denial-of-Service resilience 
• Device-level authentication and auditing 
• Secure storage and encryption 

This structured approach supports operational deployment and future EU cybersecurity certification readiness. 

Validated mitigations for GNSS and PNT threats

SecureUTM 2 phase I placed strong emphasis on GNSS jamming and spoofing risks increasingly observed in drone operations. Practical, layered mitigations were validated through a dedicated U-space proof-of-concept testbed with Hardware-in-the-Loop UAV simulations. 

Validated measures include: 

• On-board GNSS jamming detection 
• Fleet-level interference inference 
• Trajectory plausibility and conformance monitoring 
• OSNMA-based message verification 
• Structured anomaly logging and alerting 

The testbed enables repeatable attack simulation, KPI-based evaluation and regulator-ready evidence generation. 

Foundation for Phase II and European deployment

Phase I also delivered a structured U-space testbed blueprint, verification methodologies and digital twin foundations to support continued validation, operator training and continuous cybersecurity testing. 

SecureUTM 2 directly supports Belgium’s U-space deployment strategy and strengthens its position in secure drone integration. 

Phase II will focus on implementing prioritised controls, expanding validation capabilities and further aligning with EU certification frameworks.

GOSAS was aboard the Space Test Program’s (STP) Satellite-7, which launched at 4:33 a.m. PDT on April 7 from VandenbergU.S. Space Force (USSF) Base, California.

The other payloads are the Lasersheet Anomaly Resolution andDebris Observation (LARADO) instrument and the Gadolinium Aluminum Gallium Garnet (GAGG) Radiation Instrument (GARI-1C).

GOSAS will improve the reliability of navigation and communication systems for warfighters.

“The GOSAS is a CubeSat-compatible, programmable dual GPS receiver designed to characterize the orbital GNSS environment and produce high-quality ionospheric space weather products,” said Scott Budzien, PhD, NRL research physicist and GOSAS principal investigator. “Understanding and predicting space weather is critical for ensuring the accuracy of GPS and the integrity of military communications.”

GOSAS is a follow-on to the NRL experiment GROUP-C (GPS Radio Occultation and Ultraviolet Photometry-Collocated) experiment on the International Space Station that took place 2017-2023 and serendipitously detected GPS ground interference.

GOSAS originated in 2020 with the mission of increasing GPS accuracy for the warfighter.

News from the European Space Agency

In 2025, history was made as a navigation receiver on the Moon determined its position in real time using signals from approximately 410,000 km away. The receiver, called the Lunar GNSS Receiver Experiment (LuGRE), acquired signals from four navigation satellites orbiting Earth: two Galileo satellites and two GPS satellites.

The mission also tested Galileo’s Emergency Warning Satellite Service (EWSS) on the Moon, demonstrating the robustness and reach of the planned service.

With an increasing number of lunar missions planned by space agencies and private companies in the coming decades, accurate lunar navigation will be a key component of sustainable lunar exploration and the development of a lunar economy.

LuGRE, the joint Italian Space Agency (ASI) and NASA mission, showed that existing terrestrial satellite navigation systems can be used for positioning, navigation and timing on the Moon. Transported to the Moon by Firefly’s Blue Ghost, LuGRE was the first navigation receiver to operate beyond low Earth orbit.

After arriving at the Moon on March 2, 2025, LuGRE maintained connections with Galileo and GPS satellites, in double frequency, for a lunar day (14 Earth days) before powering down. The success of LuGRE laid a foundation for future navigation systems on the Moon by demonstrating the feasibility of using navigation satellites orbiting Earth to determine positions on the Moon.

Emergency warning on the Moon

In early March 2025, Qascom, the company that developed LuGRE for ASI, proposed an additional joint demonstration to test the Galileo EWSS on the Moon during the LuGRE mission. This demonstration involved ESA, the European Commission (EC), the European Union Agency for the Space Program (EUSPA) and the Centre National d’Etudes Spatiales SAR Galileo Data Service Provider (CNES/SGDSP).

With less than two weeks from proposal to execution, the partners swiftly coordinated their efforts to make the demonstration possible. 

On March 13, 2025, a simulated emergency warning message alerting astronauts to seek shelter due to high radiation exposure was disseminated via select Galileo satellites and received by LuGRE’s receiver on the Moon as part of the data collected and downloaded to Earth.

LuGRE was the idea candidate for this off-world test because it was designed to receive navigation signals. The emergency warning message of the EWSS is sent via the same signal frequency as satellite navigation signals, so LuGRE was also able to pick up and process the EWSS test signal.

The success of this demonstration on the Moon showcases the robustness and reach of the Galileo EWSS, which will enter service later this year. It also highlights the collaboration between European institutional and industrial partners, a strong example of cross-agency collaboration enabling innovation in global navigation services.

Stepping towards lunar navigation

With lunar exploration expected to increase in the coming years, ESA’s Moonlight program is developing navigation and telecommunications services for use on the Moon. By providing a unified lunar navigation and communication system, Moonlight will allow missions to focus on core activities, facilitating a long-term presence on the Moon and exploration of the Moon and beyond. Due to its compatibility with other planned lunar navigation systems, Moonlight will increase the future lunar service provision for many institutional and private users.

Newly approved at ESA’s Ministerial Council in 2025, NovaMoon will develop the first station on the Moon for high accuracy navigation. It will enhance the navigation services of Moonlight by providing an advanced geodetic and timing station on the Moon.

The survey, taking place April 4-12, will use modern geodetic methods and advanced GNSS technology. The surveyors will follow international standards to determine the height of the country’s highest peak above mean sea level (MSL) with centimeter-level accuracy, including latitude, longitude, and elevation.

Through the use of a newly developed geoid model, it will be possible to accurately convert ellipsoid heights obtained from GNSS receivers into mean sea level (MSL) elevations of the mountain peaks, according to the government.

The survey is expected to resolve the long-standing debate over whether Tajingdong, Keokradong or Saka Haphong is the country’s highest mountain peak.

The new portfolio includes six antenna models across two form factors: the FXP30x flexible PCB antenna series and the PC30x rigid FR4 PCB antenna series. Both families support cellular frequencies from 600 MHz to 8000 MHz, enabling global connectivity across multiple wireless standards.

The FXP30x series is built on Taoglas’ flexible polymer antenna technology, combining high radiation efficiency, ground-plane independence and ultra-thin construction suitable for installation inside compact device enclosures. The antennas feature peel-and-stick adhesive backing for secure mounting on non-metal surfaces such as plastic housings or glass, while flexible PCB construction allows installation in tight internal spaces where rigid antennas may not fit.

The PC30x series provides the same connectivity options in a rigid PCB antenna built on an FR4 substrate, offering a mechanically stable alternative for applications where the antenna can be mounted directly inside the device enclosure either by adhesive backing or plastic screws.

Each antenna is supplied with a pre-assembled cable and I-PEX MHF I connector. The cables are supplied in different colors to ensure accurate connections for variants that require longer cables, enabling straightforward integration with wireless modules.

Viavi’s Secure µPNT STL-1000 is a compact software-defined receiver designed to operate with the Viavi SecureTime altGNSS LEO services. Delivering precise timing with holdover capability, it enables tracking, authentication and assured navigation in denied, degraded and disrupted space operational environment, also known as D3SOE.

“With jamming and spoofing now a core element of cyber warfare, resilient PNT solutions are no longer optional,” said Doug Russell, senior vice president and general manager, Aerospace and Defense, Viavi. “The Secure µPNT STL-1000 enables assured, uninterrupted operations, especially in contested environments. Its compact size and low power consumption makes it ideal for applications that require an extremely small, low-power, secure, resilient embedded PNT receiver.”

“As the frequency of jamming and spoofing continues to rise, reliance on GPS/GNSS signals alone increasingly exposes both commercial and military operations to risk,” said Alastair MacLeod, CEO of Ground Control. “Integrating Viavi’s Secure µPNT STL-1000 into RockFLEET Assured delivers a trusted secondary position source, strengthening resilience for mission‑critical operations across defense, maritime and critical infrastructure environments.”

RockFLEET Assured is a marine-grade assured position, navigation and timing (A-PNT) solution designed to support maritime vessel navigation and oversight in GNSS-denied environments.

VectorNav Technologies has announced 95G and 250G accelerometer and 4000°/sec gyroscope ranges across its Tactical Series inertial measurement unit (IMU) and inertial navigation system (INS) product line.

The enhancement directly addresses urgent requirements from defense contractors and platform developers operating in high-G mission profiles.

Defense modernization priorities are accelerating procurements of interceptors, missiles, and hypersonic platforms that must operate through launch, interception, and aggressive maneuvering — often in environments where GPS is denied or degraded. In these conditions, navigation performance depends on the IMU’s ability to maintain solution integrity without saturating.

The extended-range Tactical Series is designed to meet that requirement, providing the core inertial measurements that enable resilient position, navigation, and timing (PNT) solutions to operate through mission-critical flight phases where conventional sensors fail.

“The demand signal from our customers has been unmistakable,” said Jakub Maslikowski, VP of Business Development. “As platforms become faster, more maneuverable, and face increasingly sophisticated threats, high-performance inertial navigation solutions are needed at scale to meet the evolving demand. With nearly 20 years supporting these mission profiles, we know these applications—and the extended-range gyro and accelerometer will enable faster integration and more rapid fielding of reliable systems.”

The extended-range accelerometer and gyroscope are available across the full VN-110 IMU and VN-210 / VN-310 INS product family, supporting applications including:

• high-speed interceptor platforms
• rapid-response strike systems 
• hypersonic and advanced maneuvering vehicles
• counter-UAS and air defense systems
• next-generation precision guidance

The extended-range configurations are drop-in compatible with existing platforms — no changes to form, fit or function — enabling immediate upgrades without redesign.

AE1a is a technology demonstration satellite developed to advance maritime digitalization by enabling wide-area, real-time vessel tracking and communications. The satellite adopts ArkEdge Space’s standardized 6U satellite bus in its large-antenna configuration. In addition to demonstrating a deployable antenna for VDES (VHF Data Exchange System) applications, AE1a will improve and validate core technologies for a VDES receiver.

AE1a will operate in coordination with AE1d, which began operations in January 2025, and AE3Va, which began operations in June 2025, forming a three-satellite constellation for demonstration across wide-area maritime areas.

AE3Va continues to acquire AIS signals across multiple sea areas, including waters around Japan and vessel-congested areas along critical shipping lanes. Accumulated reception data is being systematically verified and analyzed.

Going forward, the program will advance from reception-focused demonstration to two-way communications, including transmission from orbit. This will enable satellites to deliver operational information directly to vessels, expanding the scope of VDES demonstration and advancing progress toward concrete use-case validation across the maritime sector.
