Study of time- and distance-dependent degradations of network RTK performance at high latitudes in Norway

Abstract

Article highlights Professional satellite positioning services in the vicinity of the auroral oval region are frequently degraded during night-time. The distance between the user and the closest network receiver site is an important factor for the severity of the degradations, even at distances of only a few km. The cause of the disturbances are likely ionospheric structures related to activity in the auroral oval region.
