Correction of Spacecraft Magnetic Field Noise: Initial Korean Pathfinder Lunar Orbiter MAGnetometer Observation in Solar Wind

Junhyun Lee,
Ho Jin,
Khan-Hyuk Kim
et al.

Abstract: The Korean Pathfinder Lunar Orbiter (KPLO)-MAGnetometer (KMAG) consists of three triaxial fluxgate sensors (MAG1, MAG2, and MAG3) that measure the magnetic field around the Moon. The three sensors are mounted in the order MAG3, MAG2, and MAG1 inside a 1.2 m long boom, away from the satellite body. Before it arrived on the Moon, we compared the magnetic field measurements taken by DSCOVR and KPLO in solar wind to verify the measurement performance of the KMAG instrument. We found that there were artificial dist… Show more

“…However, magnetic cleanliness is not always feasible, especially for low cost or mass produced spacecraft such as CubeSats. The second method is gradiometry, which uses two or more magnetometers to estimate and remove the interference signals (Jo et al, 2023;Kivelson et al, 2023;Lee et al, 2023). Ness et al (1971) proposed a gradiometry algorithm that assumes the spacecraft magnetic field as a dipole and removes it using the gradient between two magnetometers placed collinearly on a boom.…”
