Magnetometer Array

Magnetometer arrays are collections of magnetic field sensors used to improve the accuracy and robustness of various applications, from navigation and mapping to mineral exploration. Current research focuses on improving calibration techniques, often integrating them directly into simultaneous localization and mapping (SLAM) algorithms using methods like particle filters and Gaussian process regression to handle noisy data and dynamic environments. These advancements are significant because they enable more reliable and efficient localization in challenging conditions, such as underwater environments or indoor spaces with significant magnetic disturbances, and improve the accuracy of data acquisition in fields like mineral exploration and robotics.
