Optimising in-flight calibration approach for the magnetometer experiment on the ESA JUICE mission

In this study the main aim has been to analyse and improve some important aspects of the in-flight calibration process for the three Earth fly-bys planned for the ESA JUICE space mission. In fact it has been developed a calibration script that is capable to correct uncalibrated data from the misallignment and scaling errors towards the expected values of magnetic field from IGRF13 model. Also the experimental process of reproduction of the magnetic field data from JUICE Earth fly-bys prooved the efficiency of the script to control the instrumentation for the gain control during the in-flight calibration. It has also been proved the low influece of the Soft Iron effect on the intrumentation, helping then to reduce the errors associated to misallignments and to the sensors offsets.
