AGL: A UWB Technology for Precise Positioning and Navigation in the Edge Spaces

This paper introduces the Agilica Geo-Location (AGL) system, an Ultra-wideband (UWB) technology-based solution designed for precise positioning and tracking in challenging edge spaces. In these environments, traditional Global Navigation Satellite System (GNSS) coverage is often obstructed or unavailable, leading to inadequate positioning accuracy. Such scenarios are critical, especially for applications like autonomous drone landing on sea vessels, where onboard structures can obstruct a large part of the sky during the landing phase. Unlike many other UWB-based solutions, AGL supports both network-centric asset tracking and device-centric navigation simultaneously, enabling scalability and adaptability. The system’s auto-calibration mechanism and robust signal processing ensure reliable performance even in challenging RF channel environments. AGL offers decimeter-level accuracy, making it suitable for robotics, unmanned vehicles, and asset tracking. Key aspects of the AGL system implementation are presented, emphasizing the importance of tight time-synchronization and addressing the impact of non-line-of-sight (NLOS) propagation. The main goal of this study is to validate the AGL system’s performance, showcasing its efficacy through benchmarking studies. The results demonstrate the AGL system capability in delivering decimeter-level accuracy, even in dynamic and high multipath scenarios.
