Short summary
The paper discusses the accuracy of the scalar magnetometer on board the scientific satellite mission Jupiter Icy Moons Explorer of the European Space Agency. A novel method is described which utilises experiments, performed with a coil system in a geomagnetic observatory, and a mathematical data processing approach to separate the systematic errors of the coil system from the systematic error of the magnetometer. With this, the paper shows that the instrument’s accuracy is below 0.2 nT (1σ).
