FlightMagNav: An Open Dataset and Probabilistic Map Learning and Validation Framework for Outdoor Magnetic Field-Based Positioning
This study addresses the absence of open datasets and standardized validation frameworks for geomagnetic localization of low-altitude unmanned aerial vehicles by constructing the first open-source geomagnetic benchmark dataset tailored for aerial platforms. Methodologically, multimodal data are acquired by integrating an optically pumped quantum magnetometer with an inertial navigation system, and a probabilistic framework for geomagnetic map learning and evaluation is proposed. The primary contributions of this work lie in bridging the critical data gap in interference-resilient, infrastructure-free localization, establishing new standards for evaluating geomagnetic positioning performance, and providing a reproducible benchmarking platform to facilitate future research in this domain.
