Improved Design of Fluxgate Magnetometer Electronics for Geospace Observation

In the last decades, magnetometers have been an important part of scientific space explorations, giving insights in the behavior of space plasmas and how they change throughout the solar system. We plan to contribute a fluxgate magnetometer for the Plasma Observatory Mission, which is an M7 candidate of ESA for making multi-point measurements in Earth's magnetosphere. This magnetometer builds on a heritage design that was already used on missions like Rosetta, BepiColombo, and JUICE. The next design iteration of the electronics introduces improvements in the feedback loop, making feedback faster and better adjusted to the currently measured values. This poster shows how the new design works and first measurements of the new electronics.
