Kplo-MAGnetometer (KMAG) is one of the scientific instruments of Korea Pathfinder Lunar Orbiter (KPLO) set to be launched in 2022. Its objectives are magnetic field investigation and technical demonstration near the surface of the Moon. Specifically, it will investigate the lithospheric magnetism of the Moon and measure the electromagnetic wave properties near the lunar surface. It consists of three fluxgate magnetometers on a 1.2 m long boom, which is relatively shorter than the boom used in other missions. The three magnetometers are included for scientific measurements, redundancy checks, and multi-sensor technical investigation. The magnetometers and an inner Anisotropic Magneto-Resistive sensor perform simultaneous sampling to correct for the magnetic field interference caused by the spacecraft. The fully integrated flight model assembly showed that the magnetometer noise level was less than 30 pT Hz^−1/2 at 1 Hz and stability was within 0.2 nT at the 10 Hz sampling rate. This paper describes the configuration and performance of the KMAG using the multi-sensing method. KPLO, THEMIS-ARTEMIS spacecraft, and Commercial Lunar Payload Service modules will be in their operational phase simultaneously. Therefore, the KMAG will be able to contribute to multi-site in-situ measurements of the lunar magnetic field. We expect that the KMAG will provide an up-to-date lunar observation data set and an opportunity to perform the multi-sensor observation.

Kplo-磁力（KMAG）是在2022年推出它的目标是磁场调查和技术论证月球表面附近的韩国探路月球轨道器（KPLO）设置的科学仪器之一。具体而言，将调查月球岩石圈磁性和测量月球表面附近的电磁波特性。它由在1.2米长的悬臂，这比在其它任务中使用的起重臂相对较短的3个磁通门磁力计。这三个磁力仪包括了科学测量，冗余校验，以及多传感器技术的调查。磁强计和内各向异性磁阻传感器进行同步采样，以校正由航天器的磁场的干扰。^-1/2在1Hz和稳定性是在10赫兹的采样率0.2 NT内。本文描述了使用多感测方法的所述KMAG的配置和性能。KPLO，THEMIS-ARTEMIS航天器，与商业月球净荷服务模块将在其操作阶段同时进行。因此，KMAG将能够有助于月球磁场的多站点现场测量。我们预计，KMAG将提供了最新的月球观测数据集，并进行多传感器观测的机会。
