The Allan variance methodology is a statistic approach, which can be used for the analysis of the noise processes. It can be used for the noise type determination of inertial sensors without the need of any transformations. Although as the Allan variance is a time domain measure, the article deals with the methodology of how to reveal the periodical interference during the noise analysis of magnetic sensors. Subsequently the methodology based on the dynamic Allan variance is applied for the cases, when the periodical interference is non-stationary and varies in time. The noise analysis determining the noise specific types is inter alia very beneficial for the in-site or in-flight magnetometer calibration.
