1. Geolocation accuracy
KOMPSAT constellation consists of two satellites, KOMPSAT-2 and KOMPSAT-3 providing optical imagery of very high resolution. Korea Aerospace Research Institute (KARI) and SI Imaging Services (SIIS) performs regular geolocation accuracy measurements. This paper presents process and result of assessment of geolocation accuracy of KOMPSAT-2 and KOMPSAT-3 imagery.
The geolocation accuracies of KOMPSAT-2 and KOMPSAT-3 are summarized in following table. This results are valid for tilt angle less than 30 degrees and exclude terrain effects.
