FENIX Project Kicks Off: The Spanish Ministry of Defence Backs Heterogeneous UAS Swarms with Technology from UAV Navigation-Grupo Oesía and Alpha Unmanned Systems

UAV Navigation-Grupo Oesía and Alpha Unmanned Systems, together with FADA-CATEC and AICIA, will advance UAS swarming technology with the support of the Spanish Ministry of Defence’s COINCIDENTE Programme.

The advanced guidance, navigation and control systems developed by UAV Navigation-Grupo Oesía, together with Alpha Unmanned Systems’ platforms, will be deployed in the FENIX project, which aims to consolidate capabilities in heterogeneous unmanned vehicle swarms. The project is framed within the COINCIDENTE Programme, the Spanish Ministry of Defence’s National R&D Plan, which seeks innovative technological solutions of interest for defence. It will also benefit from the support of institutions such as AICIA (Association for Research and Industrial Cooperation of Andalusia, University of Seville) and FADA-CATEC (Advanced Aerospace Technologies Centre).

The main objective of FENIX is the design, development and validation through simulation and flight test campaigns of a technological demonstrator for an autonomous control and coordination system for heterogeneous unmanned aerial vehicle (UAV) swarms.

The system will build on Alpha Unmanned Systems’ existing UAV platforms, as project lead, and on the advanced autopilot technology of UAV Navigation-Grupo Oesía. Building on this foundation, new technologies will be developed to endow the swarm with collective intelligence, in alignment with military doctrine. These technologies will analyse, assess and demonstrate how the use of such systems enhances effectiveness and efficiency in surveillance and reconnaissance tasks in complex and contested environments, while also providing increased robustness.

Key developments and objectives of the project include:

· Swarm coordination and planning system: Capability for efficient, real-time replanning in response to unforeseen events.

· Cooperative perception system: Integration of multisensor data collected by the different UAVs, enhancing detection accuracy and robustness against occlusions, concealment, and adverse weather conditions.

· Advanced capabilities for critical missions: Identification and mapping of areas of interest under GNSS signal interference (jamming) or spoofing, as well as in NRBQ (CBRN) threat scenarios, and detection of specific targets in patrol, reconnaissance, target acquisition, and search and rescue missions.

The use of a heterogeneous UAV swarm will enable these missions to be carried out more effectively and efficiently, directly enhancing defence operational capabilities. The FENIX system operator will only need to define the mission to be executed by the swarm through a single human–machine interface. The system will automatically decompose the mission defined by the operator into simple tasks, optimally allocate these tasks to the UAVs within the swarm according to their capabilities and constraints, and generate and assign safe, efficient, and physically feasible trajectories for each UAV, while respecting kinematic constraints, energy limitations, communication range constraints, and other operational factors.

The FENIX Project, supported by the advanced intelligence of UAV Navigation-Grupo Oesía’s GNC systems and Alpha Unmanned Systems’ rotary-wing platforms, represents a significant step forward in the use of UAV swarms for military applications. This project provides a robust and efficient tool for inspection and reconnaissance in complex and contested environments.

The Seeker unmanned aerial system, developed by Aurea Avionics, provides advanced intelligence, surveillance and reconnaissance (ISR) capabilities for defence and security users. Talos is GMV’s artillery command and control system, while DUAL-EIMOS is Rheinmetall’s 81 mm mounted mortar system

GMV, Rheinmetall and Aurea Avionics participated in a series of operational trials with the Paratrooper Brigade (BRIPAC) on 10 April at the “Príncipe” Base in Paracuellos del Jarama (Madrid). The objective of these trials was to evaluate the integration of the Seeker UAV system into an already operational architecture based on GMV’s Talos artillery command and control system and Rheinmetall’s Dual-EIMOS mounted mortar system. Dual-EIMOS has been developed by Rheinmetall’s subsidiary Rheinmetall Expal Munitions.

Seeker is a tactical, rapidly deployable unmanned aerial vehicle (UAV) , developed by Aurea Avionics and supplied by GMV, providing intelligence, surveillance and reconnaissance capabilities. The system is one of the most effective unmanned aerial systems on the market, with an endurance of 120 minutes, a range of 15 km and a weight of 3.6 kg. This system enhances the operational capabilities of the Armed Forces by providing critical real-time information to support decision-making and ensure tactical superiority on the battlefield. The activities were carried out within the framework of collaboration between the three companies, resulting in a joint solution that enables the integration of ISR sensors with fire support systems, while ensuring interoperability between platforms.

During the trials, different functionalities related to the integration were evaluated, including the definition of observation areas for the Seeker system, coordination with fire missions, the acquisition of georeferenced imagery; and the tracking of the DUAL-EIMOS system, all of these enabled through the exchange of information with the Talos system.

The trials were conducted under representative operational conditions, allowing BRIPAC operators to interact directly with the system and assess its performance in a real environment.

The integration of Seeker within the Talos–Dual-EIMOS ecosystem represents progress in the connection between sensors, effectors and command and control systems, by facilitating more agile information exchange and more effective coordination between system elements. These

activities consolidate the collaboration between GMV, Rheinmetall and Aurea Avionics in the development of advanced solutions in the field of defence.

Iridium to Acquire Aireon, Advancing its Strategy to Lead the Future of Aviation Safety 


Iridium Communications Inc., a provider of global voice, data, and positioning, navigation and timing (PNT) satellite services, announced that it has entered into a definitive agreement to acquire Aireon LLC, operator of the world’s only space-based Automatic Dependent Surveillance-Broadcast (ADS-B) air traffic surveillance system. The acquisition of Aireon is a defining step in Iridium’s strategy to provide the foundational architecture for global aviation safety, bringing space-based surveillance, safety communications, PNT, and operational data together on a single network.

“Aireon has always been part of Iridium’s aviation safety strategy. We founded it in partnership with the world’s leading Air Navigation Service Providers (ANSPs), because we believed space-based aviation safety was a generational opportunity,” said Matt Desch, CEO, Iridium. “The aviation industry is now entering an era of growing air traffic, denser airspace, autonomous aircraft, and greater expectations for safety and resiliency. Bringing Aireon fully inside Iridium better positions us to build what’s needed to support the future of aviation, including more innovations like the future introduction of space-based VHF communications.”


A Combined Platform for Aviation Safety
The acquisition unites Aireon’s surveillance and data services, including GPS jamming and spoofing detection, with Iridium’s global satcom network and PNT services that help keep GPS-dependent systems working in contested environments. This combination creates one company providing four critical aviation industry capabilities: knowing where every aircraft is, communicating with the pilots flying them, providing the navigation and timing integrity those aircraft rely on, and translating that information into operational insights that make airspace safer and more efficient. No other satellite operator delivers this combination of capabilities on a global scale.


Today, the Aireon system, which is certified by the European Union Aviation Safety Agency (EASA), flies as a payload on the Iridium satellite constellation and tracks an average of 190,000 flights per day. Commercial aircraft broadcast information such as an aircraft’s identity, location, altitude, speed, and heading. Aireon’s space-based ADS-B payload captures this information in real time, with 100% global coverage. ANSPs covering more than 50% of the global airspace rely on Aireon data to create safer and more efficient airspace.


The world’s leading ANSPs and investors in Aireon, including NAV CANADA and NATS (United Kingdom), AirNav Ireland, ENAV (Italy), and Naviair (Denmark), each played a vital role in launching the Aireon service, proving its reliability, and establishing it as a critical part of the global air traffic control infrastructure. NAV CANADA and NATS, which together manage the most heavily trafficked oceanic airspace in the world – the North Atlantic Tracks between Europe and North America, were the first to go live with the service. In connection with the acquisition, both ANSPs will sign extended data services agreements through 2035 and beyond, with provisions for continued cooperative development of space-based VHF communications and other new capabilities.


“Aireon and Iridium have been partners since day one, and that partnership is the reason we have been able to build the world’s only space-based air traffic surveillance system and a fast-growing aviation data services business alongside it,” said Don Thoma, CEO of Aireon. “Becoming part of Iridium is a natural next step for our team, our customers, and our roadmap, particularly as our data products expand into new areas like turbulence detection and aviation data analytics. Together, we are building the foundation for the future of global aviation.”


“NAV CANADA is proud of our foundational role in establishing Aireon’s world-first technology,” said Mark Cooper, President and CEO, NAV CANADA. “This sale sharpens our focus on our core expertise: keeping Canada’s skies safe. As a fellow founding partner, Iridium is the ideal owner to guide Aireon’s continued commercial growth. We wish the entire team continued success and look forward to our ongoing relationship as a customer.”


“We have been proud to be a part of Aireon’s successes, most notably making real-time aircraft surveillance over the Atlantic a reality for the first time in history, enabling even safer operations across the North Atlantic,” said Martin Rolfe, CEO, NATS. “As a shareholder for the past eight years, it is now the right time for us to divest. We are confident Aireon is well positioned for the future and wish the team every success in the next stage of its development.”


The Next Transition: Space-Based VHF
Space-based VHF communications represent a major opportunity in air traffic management, extending pilot-to-controller VHF services into oceanic and remote airspace where ground infrastructure cannot reach, without the need for additional aircraft equipment. The model is similar to how aircraft already carry ADS-B transceivers, which enables Aireon to deliver space-based ADS-B surveillance without requiring fleet retrofits.


Aireon’s Growing Data Services Business
Beyond surveillance for ANSPs, Aireon operates a fast-expanding aviation data services business that sells real-time and historical aviation data to airlines, airports, OEMs, governments, and aerospace operators. Product lines already available or launching this year include turbulence detection, GPS jamming and spoofing detection, and safety and efficiency analytics. Additional applications are also in development to support the rapidly evolving airspace environment.

Aireon’s data business is one of its highest-growth areas today and is expected to be a meaningful contributor to the combined company’s aviation growth.

Rethinking Runoff: How Diverter Valves Protect Infrastructure, Operations, and the Environment

By: Chris Eberly, PE, Vice President Product Development at NWPX Park

Water management in commercial and industrial environments is rarely as simple as installing a drain. In outdoor wash areas, fuel loading pads, aircraft hangars, retail service zones, and data center campuses, runoff can originate from two fundamentally different sources — routine rainfall and active wash operations. Each demands a different destination. Rainwater is typically required to discharge to storm systems, while wash water containing oils, detergents, fuel residues, and debris must be routed to sanitary sewer systems or containment for treatment. Improper flow routing is not just a design flaw — it is a compliance failure that can trigger regulatory violations, environmental damage, and operational shutdowns.

Diverter valves are engineered to resolve this conflict. Installed below grade within catch basins or vault structures, these systems automatically direct runoff to the appropriate discharge point based on operating conditions. Rather than relying on manual intervention, they create a multi-path hydraulic control point between storm, sanitary, and containment pathways. This transforms runoff management from a binary decision into a configurable routing strategy aligned with site-specific risks and regulatory requirements.

For engineers, municipalities, and facility owners, this capability transforms runoff management from a compliance vulnerability into a predictable, engineered solution.

The Engineering Principles Behind Diversion Systems

At its core, a diverter valve functions as a multi-path hydraulic control point, transforming runoff management into a controlled routing system capable of directing flow between stormwater, sanitary, and containment pathways as conditions change.

When wash operations begin, the system diverts that runoff to the sanitary sewer or a designated holding tank for treatment. This hydraulic control point ensures that rainwater does not overload wastewater treatment facilities, while contaminated wash water does not enter storm systems that discharge directly into rivers, lakes, or coastal waters.

Two primary system configurations are used, depending on site conditions and surface area: Demand-Driven and First Flush.

In smaller wash zones — generally 200 square feet or less — a demand-driven configuration is often sufficient. In this design, the system senses water flow in the supply line to a pressure washer or wash system. When flow exceeds a defined threshold, typically around half a gallon per minute, the valve automatically opens to divert runoff to sanitary treatment. Once washing stops, the valve returns to its default position directing water to storm. This approach requires no manual switching and avoids the operational risk associated with human error.

For larger paved areas, the first flush principle becomes critical. This configuration builds upon the same demand-driven activation but incorporates a PLC (Programmable Logic Controller)-controlled process to capture and treat the initial runoff volume. The “first flush” refers to the initial half-inch of rainfall over a surface area—the portion most likely to mobilize accumulated oils, hydrocarbons, and debris. Engineers calculate this volume based on site area, and the system then meters and releases runoff in controlled batches, repeatedly cycling the valve until the full volume has been diverted for treatment.

In many applications, these two approaches are integrated within a single system, providing continuous protection across both operational and environmental conditions while scaling from compact retail pads to large industrial sites and airport tarmacs.

Because these systems operate below grade in moisture-prone environments, reliability is essential. Many installations employ hydraulically actuated valves rather than fully electric motorized assemblies, reducing exposure-related maintenance concerns in subterranean vaults. The result is a largely maintenance-free solution designed for long-term service.

Diversion Configurations and Application Scenarios

Diversion systems are often viewed as simple two-path controls—directing flow between stormwater and sanitary systems. In practice, however, modern infrastructure requires more flexible routing. Based on site risk, regulatory requirements, and operating conditions, systems can be configured in several ways.

Three-way diversion (common configurations):

Stormwater ↔ Sanitary Sewer
The most common configuration for washdown applications. Runoff flows to stormwater under normal conditions and is diverted to sanitary during wash events.
Applications: wash racks, dumpster/compactor areas, maintenance pads.

Sanitary Sewer ↔ Spill Containment
Used where storm discharge is not permitted. Runoff is directed to sanitary under normal conditions and to containment during spills or controlled events.
Applications: medical decontamination, hazardous wash areas, spill prevention.

Stormwater ↔ Spill Containment
Runoff is typically discharged to stormwater but diverted to containment during fueling or spill events.
Applications: fuel transfer areas, loading racks, aviation fueling or deicing.

Four-way diversion (advanced configurations):
Stormwater ↔ Sanitary Sewer ↔ Spill Containment
These systems provide maximum flexibility, allowing runoff to be routed based on real-time conditions such as rainfall, wash activity, or emergency events.
Applications: medical decontamination facilities, high-risk industrial sites, critical infrastructure.

Expanding Applications Across Infrastructure Sectors

While wash racks are a natural application, diversion systems are increasingly being specified in a wider range of facility types. Dumpster and compactor areas represent one of the most overlooked runoff challenges. Liquids generated from solid waste accumulation often mix with rainwater and discharge directly to storm systems when left unmanaged. As regulatory awareness increases, some municipalities now require diversion or pretreatment systems in dumpster enclosures. What was once viewed as a housekeeping issue is now recognized as an environmental compliance concern.

Fuel loading and unloading zones present another critical use case. Facilities handling diesel, aviation fuel, or other hydrocarbons must comply with spill prevention and discharge regulations. In these environments, diversion systems route runoff either to storm drains during normal conditions or to containment tanks when fueling activities occur. Failure to implement compliant controls can expose operators to significant financial penalties and operational risk.

Aircraft hangars equipped with aqueous firefighting foam systems require similar diversion capabilities. During suppression events, foam discharge must be routed to holding tanks rather than municipal sewer lines. The same underlying valve technology can serve these specialized scenarios.

Emerging markets are also driving adoption. Data centers, for example, rely on large-scale cooling infrastructure that often requires periodic washdown. Municipalities increasingly prohibit untreated wash water from entering storm systems. In colder climates, frost depth considerations may necessitate deeper installations, insulated vault assemblies, or integrated heating elements. These projects demonstrate that diversion systems are not static catalog products but adaptable engineering platforms capable of responding to complex site constraints.

Structural Integration and Long-Term Durability

Installation flexibility is a significant advantage of modern diversion systems. In new construction, diverter valves can be integrated directly into precast concrete vaults, delivering a complete, traffic-rated structure ready for installation. Precast construction offers proven structural integrity, long service life, and resistance to deformation. Because many wash and fueling areas are located in parking lots or high traffic zones, vaults must withstand vehicular loading, from service trucks to aircraft support equipment.

Retrofit scenarios are also common. Systems can often be installed within existing catch basins, provided separate storm and sanitary connections are available. Coordination between civil and plumbing disciplines is typically required, particularly when adding pressurized supply lines for demand activation. However, once installed, these systems operate with minimal routine maintenance.

Within the portfolio of NWPX Park, a division of NWPX Infrastructure, diverter valves are incorporated into engineered, pre-plumbed precast systems rather than supplied as isolated components. These engineered systems may integrate separators, screening components, or additional treatment elements within a unified vault assembly. Delivering a factory-assembled system reduces field complexity, improves quality control, and ensures that the diversion mechanism performs as designed.

Customization is another factor critical to performance. Whether adapting to deep frost lines in northern climates, integrating filtration for marine facilities, or designing for heavy-load runway environments, diversion systems can be scaled and configured to meet project-specific demands. This ability to refine and recombine established technologies allows engineers to respond to evolving regulatory expectations without compromising durability.

Diversion as a Strategic Compliance Tool

Environmental regulations governing stormwater discharge and wastewater treatment continue to evolve. Municipalities and state agencies are placing greater emphasis on preventing contaminated runoff from entering natural waterways. As awareness increases around the environmental impact of uncontrolled discharge, diversion systems are shifting from optional enhancements to specified infrastructure elements.

For design engineers and facility owners, the benefits extend beyond avoiding fines. Proper diversion protects municipal treatment capacity, reduces pollutant discharge to receiving waters, and demonstrates proactive environmental stewardship. It also positions facilities to adapt to tightening discharge standards without costly retrofits in the future.

Runoff will always occur. The difference lies in whether it is directed intentionally or allowed to follow the path of least resistance. Diverter valves provide a controlled, engineered solution that aligns infrastructure performance with environmental responsibility, an outcome increasingly demanded by regulators, municipalities, and project stakeholders alike.
