The GOCE mission is a dedicated gravity field mission. Since the satellite carries three fluxgate magnetometers, these have been calibrated and characterized for pertubations. The standard deviation of geomagnetic quiet time residual with high-performance geomagnetic field model (CHAOS7) is below 13 nT.
