About KMAG
KMAG, developed by Kyung Hee University, is a magnetic field measurement instrument that consists of 3 magnetometers (MAGs) inside a 1.2-meter boom structure. Each MAG is a triaxial fluxgate designed to measure a ±1000 nT range of DC magnetic fields with 0.2 nT resolution [1]. The scientific objectives are the investigation of the lunar magnetic field and near-Moon space environment.

: In the BLT cruise phase, KMAG on-orbit calibration processes were performed successfully. The level 1 data processing pipeline has been verified and confirmed by way of comparison with DSCOVR. But there still remain some issues such as spatial distortion effect of spacecraft body, removing unwanted disturbances by artificial events and long-term stability. Because KMAG has three fluxgate magnetometers in the boom and one AMR sensor inside the spacecraft body, we are analyzing the data to distinguish the noise signal with a multi-sensing method. For a more reliable quality of data products, we are studying more delicate calibration with ICA numerical methods and machine learning etc.
