The Suomi NPP launched on 28 October 2011 hosts the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor. The VIIRS sensor includes a Day-Night-Band (DNB) which is unique in its ability to maintain near constant ground footprint across the entire swath. In this paper, we will demonstrate the performance of the DNB geolocation. We will show how the corrections to DNB geolocation parameters are derived, the estimated accuracy before and after the application of various geolocation corrections to the operational data processing system and the long term trend in DNB geolocation accuracy.
