DAF-MIT AIA Flight Data: Magnetic Navigation Sensor Readings

Flight data collected by Sander Geophysics Ltd. near Ottawa, Canada, supports research on airborne magnetic anomaly navigation (MagNav). The dataset contains scalar and vector magnetic field measurements from nine magnetometers, alongside GPS, inertial navigation, and aircraft system data. Purposeful in-flight disturbances and varied flight patterns provide a diverse testbed for signal enhancement algorithms.

Use Cases

• Developing signal enhancement algorithms for magnetic navigation based on noisy in-aircraft and clean tail-boom magnetometer readings.
• Training machine learning models to correct aircraft-induced magnetic interference using data from controlled disturbance events.
• Benchmarking sensor fusion techniques that combine magnetic, inertial, and GPS data for precise positioning.
• Studying the characteristics of the Earth's magnetic field and temporal anomalies from airborne platform measurements.

Strengths

• Includes a clean magnetic reference signal from a tail stinger, enabling supervised learning for noise correction.
• Contains data from purposeful temporal disturbances (e.g., control surface movements, fuel pump cycles) to model interference.
• Covers two years of collection (2020-2021) with varied flight patterns and altitudes, providing operational diversity.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided in the available descriptions.
• The exact date of the last update is unknown, which may affect perceived data freshness.
• Documentation appears to be spread across datasheets and flight-specific readmes, which may require effort to navigate.
