  "abstract": "Electronic spin systems with S>1/2 are usefull for DC vector magnetometery, since the conventional electron spin resonance spectra at a given magnetic field reflect not only the field strength but also the orientation in the presence of strong spin-spin interactions. S=1 spins, e.g. the nitrogen-vacancy centers in diamond, have been intensively investigated for such a purpose. In this report we compare S=1 and S=3/2 spins, and discuss how one can make use of high spin systems as a vector magnetometer. We find analytical solutions which allow reconstruction of magnetic field strength and polar angle using the observed resonance transitions if an uniaxial symmetry exists. We also find that ambiguity on determining the field parameters may arise due to unique properties of S=3/2 systems, and present solutions utilizing additional transitions in the low field region. The electronic spins of the silicon vacancy in silicon carbide is introduced as a model for the S=3/2 DC vector magnetometer and the practical usage of it including magic-angle spinning type methods is presented too.",
