“…To study the intercorrelation between the EEJ and EIA, the Ionospheric Anomaly Monitoring by Magnetometer And Plasma-probe (hereafter, IAMMAP) was proposed and selected as a scientific instrument for use on the Compact Advanced Satellite 500-3 (CAS 500-3), which is planned to be launched by the KSLV (Korean Space Launch Vehicle) in 2025. The IAMMAP includes a Langmuir probe and an impedance probe, the design and test results of which were reported in [9]. Here, we report on a set of temperature-tolerant high-precision fluxgate magnetometers, named AIMAG (Adaptive In-phase MAGnetometer), which is employed as a part of the IAMMAP instrument suite to study the complicated current system in the ionosphere and magnetosphere, especially in relation to the EEJ.…”

Ionospheric Anomaly Monitoring by Magnetometer And Plasma-probe (IAMMAP) is a suite of scientific instruments used in the Compact Advanced Satellite 500-3 (CAS 500-3), which is planned to be launched by the KSLV (Korean Space Launch Vehicle) in 2025. The main scientific objective of IAMMAP is to understand the complicated correlation between the equatorial electrojet (EEJ) and the equatorial ionization anomaly (EIA), both of which play important roles in the dynamics of ionospheric plasma in the dayside equator region. The magnetic field generated by the EEJ is tiny (~several nT) compared to the background geomagnetic field (~30,000 nT); thus, a high-resolution magnetometer with a wide dynamic range is required to investigate its correlation with the EIA. To achieve this required resolution, IAMMAP includes a set of improved fluxgate magnetometers named the AIMAG (Adaptive In-phase MAGnetometer), which was developed by adopting new technologies. Here, we report the analysis results of the manufactured AIMAG performance based on trade-off studies for optimizing the circuit and sensor configurations. The results support that the AIMAG sensor and electronic circuits with new concepts and technologies will lead to successful observations of EEJ signatures in the ionosphere.
