In a method for the operation of a magnetic resonance apparatus, wherein a positional change of a region of an examination subject to be imaged relative to an imaging volume of the apparatus is acquired with orbital navigator echos, at least one reference dataset with data points is generated, the data points in the k-space, at least on a partial surface of a spherical surface, being arranged to occupy the partial surface in surface-covering fashion, and the partial surface extending at least around a great circle of the spherical surface corresponding to a maximally expected angular range of the positional change. For acquiring the positional change, a dataset of at least one of the navigator echos is compared to the reference dataset.
