About
Magson’s Science Magnetometer is a high-performance, space-qualified fluxgate magnetometer instrument designed for use as a scientific payload on spacecraft. It has been designed, manufactured, and qualified in accordance with common space standards (ECSS) to satisfy demanding mission requirements and constraints. The instrument is built around a vector-compensated ringcore sensor with three pickup coil pairs for the X, Y, and Z components, plus a compensating feedback coil system, ensuring temperature-independent axis alignment and long-term measurement stability. Excitation circuitry, preamplifier, feedback current sources, and precision ADC/DAC electronics are combined with FPGA-based digital signal processing. Magson science magnetometers have flown on numerous ESA, DLR, and international missions including BepiColombo (MMO/MPO), JUICE (JMAG-IB), Rosetta Lander, Venus Express, Themis, Double Star, and MASCOT on Hayabusa2, providing precise magnetic field vector measurements for planetary and heliophysics science.
