High-Precision Local Positioning System for GPS-Denied Drones & Robotics

Why It Matters

By providing GPS‑independent navigation, AGL unlocks reliable autonomous operations in contested or GPS‑denied zones, a critical capability for defense, logistics and emerging eVTOL services.

Key Takeaways

• Centimeter-level accuracy using UWB time-of-flight
• Operates without GPS, resistant to jamming
• Scalable mesh supports thousands of tags
• Passive tags low SWaP, output NMEA data
• Enables indoor/outdoor, maritime, eVTOL drone operations

Pulse Analysis

The rise of GPS‑denied scenarios—whether due to intentional jamming, urban canyon effects, or indoor missions—has driven the need for alternative navigation methods. Ultra‑wideband (UWB) technology, with its short‑range pulses and precise time‑of‑flight measurements, offers a robust foundation for local positioning. Agilica’s Geolocation (AGL) system builds on this premise, creating a self‑contained coordinate grid through fixed anchor nodes that synchronize to sub‑nanosecond precision, enabling drones to determine their location with 10‑centimeter fidelity regardless of satellite availability.

Beyond raw accuracy, AGL’s architecture emphasizes scalability and low impact on payload. The passive tags are engineered for minimal size, weight, and power (SWaP) while delivering industry‑standard NMEA streams via UART, CANbus, or USB, simplifying integration with existing flight controllers. Mesh networking allows an unlimited number of tags to coexist, supporting large‑scale swarms or mixed fleets of aerial and ground assets. Moreover, the system’s interference‑resistant design mitigates multipath and RF noise, making it suitable for complex environments such as ship decks, warehouses, and dense urban corridors.

Strategically, the availability of a GPS‑independent positioning platform reshapes several market segments. Defense operators gain a resilient navigation layer for reconnaissance and strike missions where GNSS signals are contested. Commercial logistics can deploy autonomous drones for indoor inventory checks or last‑mile delivery in cities without fearing signal loss. Emerging eVTOL and droneport concepts also benefit from precise take‑off and landing on moving platforms. As regulatory frameworks evolve to accommodate beyond‑visual‑line‑of‑sight operations, solutions like AGL will become pivotal in ensuring safety, reliability, and scalability across the unmanned ecosystem.
