Verification of the JUICE Spacecraft Magnetic Cleanliness and Emitted Field Modelling

This paper presents the magnetic verification of the JUICE spacecraft, aiming to verify its magnetic cleanliness in a frequency range up to 20 kHz. The approach includes con-ducting tests with synchronous measurements using multiple magnetometers and modelling the emitted field through a multipole expansion method. The field is extrapolated from the sensor positions to the points where the magnetic requirements are specified. The test results demonstrate that the JUICE spacecraft is magnetically very clean, and provide valuable information for the design and operation of future spacecrafts.
