Unhackable Horizons: New Tech Steers Ships in a GPS-Denied World

SANTA CLARA, CA – April 20, 2026 – In a move that directly confronts the growing threat of electronic warfare at sea, ANELLO Photonics and BlackSea Technologies have announced a landmark partnership. ANELLO's high-precision inertial navigation system will be integrated into BlackSea's Chaser uncrewed surface vessel (USV), creating an autonomous maritime platform designed to operate effectively even when GPS signals are jammed, spoofed, or entirely unavailable.

The collaboration equips the state-of-the-art drone ships with a navigation solution built on ANELLO's proprietary Silicon Photonics Optical Gyroscope (SiPhOG™), a technology that promises to maintain course and positioning with extreme accuracy, independent of external satellite signals. This addresses a critical vulnerability for modern naval and commercial fleets, ensuring that autonomous systems can complete their missions in increasingly contested global waterways.

The Unseen Battle on the Airwaves

For years, the Global Navigation Satellite System (GNSS), most commonly known as GPS, has been the invisible bedrock of global logistics and military operations. However, its unencrypted signals are a soft target. In recent months, reports of widespread GPS jamming and spoofing have escalated dramatically. In March 2026, over 1,100 ships in the Middle East Gulf experienced severe disruptions, with navigation systems erroneously placing them miles inland or at nearby airports.

These incidents are not isolated. From the Baltic Sea to the Strait of Hormuz and the Black Sea, electronic warfare has become a staple of modern conflict and geopolitical tension. Adversaries use sophisticated jammers to create navigational chaos, mask illicit activities, or gain a tactical advantage. For an uncrewed vessel reliant solely on GPS, such an attack can be mission-ending, causing it to go off-course, abort its task, or become lost at sea. This erosion of trust in satellite navigation has created an urgent demand for resilient, self-contained positioning, navigation, and timing (PNT) solutions.

"Reliable navigation is fundamental to autonomy, safety, and mission assurance," said Dr. Mario Paniccia, Co-Founder and CEO of ANELLO Photonics. "With the ANELLO Maritime INS now integrated into the Chaser platform, we are delivering proven, high-performance inertial navigation that maintains precise positioning and heading even in GPS-denied environments."

A Gyroscope on a Chip

At the heart of the new partnership is ANELLO's SiPhOG™ technology. Traditional high-performance navigation systems often rely on bulky and expensive Fiber Optic Gyroscopes (FOGs). ANELLO has miniaturized this concept, etching a complex optical gyroscope onto a silicon chip roughly the size of a grain of rice, measuring just 2 by 5 millimeters. This integrated photonic system-on-chip has no moving parts and consumes about one-tenth the power of older FOGs, making it ideal for deployment on autonomous platforms where space, weight, and power are at a premium.

The system works by measuring rotation using light. By detecting minuscule changes in the phase of light traveling through microscopic on-chip waveguides, the SiPhOG™ provides a continuous, high-fidelity stream of orientation and movement data. This allows the vessel to calculate its position through dead reckoning with exceptionally low drift—less than 0.5 degrees per hour. Furthermore, ANELLO’s system incorporates an AI-based sensor fusion engine designed to intelligently detect GNSS spoofing attempts and integrate data from multiple sensors, ensuring the vessel maintains a clear picture of its location and heading at all times.

This breakthrough bridges the gap between costly, defense-grade FOGs and less-capable MEMS sensors, offering fiber-optic-class performance at a price point that enables deployment at scale across entire fleets of autonomous vehicles.

The Autonomous Tip of the Spear

The technology is being integrated into a platform already proven in the field. BlackSea Technologies' Chaser USV is the next-generation evolution of its Global Autonomous Reconnaissance Craft (GARC), a platform of which over 350 units have been delivered to the U.S. Navy. These vessels have logged tens of thousands of operational hours in real-world deployments, providing a battle-tested foundation for the new Chaser model.

Designed for tactical autonomy at scale, the Chaser is a modular platform capable of a wide range of missions, including maritime surveillance, intelligence gathering, contested logistics, and acting as a communications relay. Its ability to operate persistently in complex environments makes it a cornerstone of the U.S. Navy's vision for a larger, more distributed fleet. The integration of ANELLO's resilient PNT solution is a critical force multiplier.

"Our collaboration with ANELLO enables a new level of navigation resilience for maritime autonomy," said Timothy O'Connor, CSO at BlackSea Technologies. "By incorporating ANELLO's advanced inertial navigation technology, we are strengthening the reliability and mission capability of the Chaser platform for our customers."

Redefining the Market for Maritime Autonomy

The partnership between the Silicon Valley tech firm and the Baltimore-based defense platform developer highlights a major shift in the defense market. The global USV market, valued at over $1 billion in 2025, is projected to nearly double by 2030, driven primarily by defense spending and the strategic imperative to counter threats in contested domains. While established defense giants like Northrop Grumman and Honeywell offer robust navigation systems, the ANELLO-BlackSea collaboration is positioned to disrupt the market by integrating a next-generation, cost-effective solution directly into a platform that is being produced at scale.

This move is about more than just a single contract; it represents a new standard for autonomous systems. As nations race to build out their fleets of drone ships, submarines, and aircraft, the ability to operate reliably without GPS is no longer a luxury but a fundamental requirement. This partnership provides a clear solution, accelerating the modernization of naval fleets and setting a new benchmark for resilience and mission assurance in the era of autonomous warfare.
