Abstract

In a process for filtering the consecutive results yi of a north-seeking gyroscope which are ooverridden by interference signals, the difference between the extreme measured values within a time window is determined. Only if this difference is less than a given maximum deviation y is the means value of the measurements in this time window given as the corrected direction of north.
