oneNav’s Artificial Intelligence (AI) engine can improve deep urban GNSS accuracy by 2-3x

Sunnyvale, California, 29 August 2022
– Silicon Valley, California-based technology company oneNav today released field test data demonstrating the current release of its Artificial Intelligence (AI) engine improving deep urban GNSS position accuracy by 2-3x at a 95% confidence level. The pureL5 GNSS receiver customer evaluation system (CES) on average produced 5-meter or better accuracy in San Francisco financial district driving tests. The pureL5 CES demonstrates only L5 code phase to show baseline accuracy, directly acquiring the L5 signal without relying on L1. Adding the use of carrier phase will improve accuracy and adding additional sensors will smooth performance even further.

Multipath signal bounces comprise a significant portion of GNSS positioning errors in difficult signal environments, such as urban canyons, because they traditionally are difficult to correct. oneNav’s trained AI engine can produce Excess Path Length (EPL) corrections to improve position accuracy in these types of environments. An AI engine which uses L5 signals is better than a similar engine using L1 signals, because the L5 signal is able to resolve non-overlapping reflections that L1 cannot.

oneNav pureL5 GNSS CES field tests currently are in process with major OEMs and silicon companies in South Korea, China, Europe and throughout California. Are you interested in evaluating the world’s only direct acquisition L5 for mobile, wearables, and IoT devices? Please email Ellen Kirk at – we’ll talk.
