Mastering the Skies in the Age of Electronic Warfare

The modern battlefield is increasingly defined by the invisible war of the electromagnetic spectrum. GPS signals are jammed, radio communications are disrupted, and traditional drone operations, once a tactical advantage, can be rendered useless. In this challenging environment, a new breed of defense technology is emerging, one that prioritizes resilience, autonomy, and affordability. At the forefront of this revolution is Lendurai, an Estonian startup that is fundamentally changing how unmanned aerial vehicles (UAVs) operate in contested spaces.

Lendurai isn’t just building drones; they’re developing the brains that allow drones to think for themselves, to navigate without satellite signals, and to communicate even when traditional radio links are cut. Their focus on “GNSS-denied and radio-jammed environments” speaks directly to the most pressing challenges faced by modern militaries. By leveraging cutting-edge computer vision and machine learning, Lendurai is empowering drones to operate autonomously, reducing reliance on vulnerable external signals and significantly enhancing their survivability and effectiveness in the most demanding scenarios.

Born from Experience, Forged in Necessity

Lendurai, founded in 2024 and based in Tallinn, Estonia, is the brainchild of a team with deep roots in AI, autonomy, and commercially scaled hardware. Siim Maivel, the CEO, previously led AI development at Bolt, a European mobility unicorn. Mark Cowan, the CTO, brings experience as a lead software engineer from Open Cosmos, a space technology company. Sergii Kharagorgiiev, Head of AI Research, was the computer vision lead at Starship Technologies, known for its autonomous delivery robots. This fusion of diverse, high-level expertise from various tech sectors is a significant differentiator, allowing Lendurai to approach defense challenges with innovative solutions not always found in traditional defense contractors.

Their genesis is rooted in the recognition of a critical gap in existing drone technology. While First-Person View (FPV) drones offer a low unit cost, their operational overhead is substantial. They typically require a team of four operators in the field, plus an additional eight support staff for preparation and maintenance. Even with this extensive support, a staggering 70% of FPV UAVs can fail in the field due to radio jamming. Lendurai set out to solve this, not by simply building a better drone, but by creating an entirely new paradigm for drone autonomy.

The urgency of their mission is underscored by CEO Siim Maivel’s poignant observation: “European defense can’t wait.” This statement reflects a keen awareness of the geopolitical landscape, particularly along Europe’s eastern frontier, where electronic warfare and GPS jamming have become routine. Lendurai’s commitment to manufacturing its products in Estonia using European components further reinforces their dedication to European technological sovereignty and ensures their solutions meet stringent NATO standards for military procurement.

The Core Technology: Autonomy Unshackled

Lendurai’s flagship offering is its proprietary autonomy stack – a dual-use platform designed for both military and public sector clients. This on-board solution delivers advanced autonomous navigation capabilities that are independent of Global Navigation Satellite Systems (GNSS) and traditional radio control. This is where their expertise in computer vision and machine learning truly shines.

Imagine a drone flying a reconnaissance mission over enemy territory. Suddenly, GPS signals are jammed, and radio communication with the operator is lost. For a traditional drone, this is often a mission-ending event, potentially leading to the loss of a valuable asset and critical intelligence. A Lendurai-powered drone, however, continues to operate. Its on-board AI, utilizing advanced computer vision, processes visual data from its environment in real-time, allowing it to:

• Navigate autonomously: By analyzing landmarks, terrain features, and object recognition, the drone can maintain its course and complete its mission without relying on external positioning signals.
• Avoid obstacles: The AI can detect and react to obstacles, adjusting its flight path to prevent collisions, even in complex or cluttered environments.
• Adapt to changing conditions: The system can dynamically adjust to variations in lighting, weather, and unexpected environmental changes.
• Execute complex maneuvers: From precise inspections to payload deployment, the AI enables the drone to perform intricate tasks with high accuracy, even without continuous human input.

This on-board autonomy drastically reduces the total cost of ownership by minimizing personnel requirements and increasing mission success rates. Instead of weeks of intensive training for FPV drone operators, Lendurai’s UAVs reportedly require less than two days of operator training – a remarkable leap in deployability and accessibility for advanced drone technology. This ease of use and reduced reliance on large support teams make Lendurai’s solutions significantly more agile and cost-effective for deployment in the field.

Dual-Use Capabilities: From Battlefield to Beyond

While Lendurai’s immediate focus is on military and defense applications, their technology is inherently dual-use. This means the same core autonomy stack that allows a military drone to operate in a jammed environment can also be applied to civilian use cases. For instance:

• Infrastructure Inspection: Drones can autonomously inspect power lines, pipelines, and bridges, even in remote areas where GPS signals might be weak or intermittent.
• Agriculture: Autonomous drones can monitor crops, assess soil health, and apply precision treatments, optimizing yield and reducing resource waste.
• Energy Monitoring: Inspection of wind turbines, solar farms, and other energy infrastructure can be performed efficiently and safely without human proximity.
• Search and Rescue: Drones can autonomously search vast areas for missing persons or disaster victims, even in challenging terrain or poor visibility.

This dual-use approach offers several advantages. It allows Lendurai to tap into a broader market, fostering rapid development and scaling of their technology. Furthermore, the rigorous demands of military applications often lead to more robust and reliable solutions that then benefit civilian applications, creating a powerful feedback loop for innovation.

The Defense Implications: Resilience and Strategic Advantage

Lendurai’s technology holds profound implications for the defense sector, particularly in the context of:

• Electronic Warfare (EW) Resilience: In an era where adversaries actively seek to disrupt GPS and radio communications, Lendurai’s ability to operate independently provides a critical tactical advantage. It ensures that reconnaissance, targeting, and other vital drone-enabled missions can continue even under severe jamming conditions.
• Reduced Vulnerability: By minimizing reliance on external signals, the drones become less susceptible to sophisticated EW attacks, improving their survivability and mission success rates.
• Enhanced Operational Flexibility: The reduced training requirements and the ability to operate with fewer personnel on the ground mean military units can deploy and utilize advanced drone capabilities more rapidly and efficiently. This flexibility is crucial for adapting to fast-evolving battlefield situations.
• Cost-Effectiveness: While delivering high-end autonomy, Lendurai aims to achieve this at a fraction of the cost of traditional systems. This affordability is achieved by scaling technology precisely to mission requirements and using mass-produced, readily available hardware, making advanced drone capabilities more accessible to a wider range of defense forces, including those with more constrained budgets.
• Interchangeable Payloads: Lendurai’s dual-use platform supports interchangeable payloads, increasing the versatility and survivability of their drones. This means a single drone platform can be rapidly reconfigured for different missions, from surveillance to direct action, enhancing adaptability in complex operational environments.
• Sovereignty by Design: Manufacturing in Estonia with European components ensures that Lendurai’s products are compliant with NATO standards and offer a sovereign solution, reducing reliance on non-allied supply chains for critical defense technology.

Mikolaj Firlej, Co-Founder and General Partner of Expeditions Fund, an investor in Lendurai, encapsulates this advantage: “Often, end-users must choose between cost efficiency and high performance. Lendurai stands apart by delivering advanced computer vision for GNSS-denied environments at a fraction of the market price.”
