[PEM12-P32] Magnetic Field Measurement in the Ionosphere by using 2U-size CubeSat
Keywords:CubeSat, Sq current system, Fluxgate magnetometer
In this study, the fluxgate magnetometer is installed in the CubeSat to observe the 3D fine structures of Sq current system. The thermal vacuum test was conducted for the fluxgate magnetometer to confirm the temperature drift of the sensor. As a result, the temperature drift of the magnetic sensor is less than 1nT/degree which is satisfy the requirement of the specification for observations of the Sq current. In addition, the fundamental feasibility studies depending on the electric power budget, orbital life time, the communication capacity, and specification of the magnetometer show that the observation of the Sq current by CubeSat is well feasible with a short duration of the development and quite low-cost.
