Zusammenfassung
We had common technical requirements for the magnetic field measurement in the ARASE(ERG) mission to study the the Earth's radiation belt and the BepiColombo mission to study the Mercury environment. We had to build very precise magnetometers which are small, light and low power-consumption as well as being tolerant of the severe radiation in the Earth's radiation belt and around Mecury. We first investigated and developed MGF-I, one of two magnetometers for the BepiColombo MIO(MMO) satellite. For MGF-I, the tolerance to the high-temperature environment was also required. Another magnetometer, MGF, with almost the same design as MGF-I, was built and installed on the ARASE satellite. ARASE was launched in 2016 and has been continuously observing the radiation belt for six years since it started regular observations in March 2017. Thereafter, BepiColombo was launched in October 2018. It has performed one Earth flyby, two Venus flybys, and two Mercury flybys until 2022. The observations by MIO are mainly performed at flyby events until the Mercury orbit insertion in 2025. Due to the strict limitations and restrictions of the data, it is not easy to evaluate precisely the in-flight performance of MGF-I on BepiColombo MIO. We are investigating the performance of MGF-I based on our knowledge and analysis of data from ARASE MGF. We report the results and discuss the perspective of the observation by BepiColombo MIO MGF-I after the insertion to the orbit around Mercury.
