Abstract
In this work a method is presented for the navigation of National Oceanographic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA AVHRR) images based on an orbital model and on the use of control points. The orbital model assumes a circular orbit whose parameters are derived using the TBUS messages and one or more ground control points. The errors caused by these simplifications are corrected by means of linear functions which relate the coordinates measured in the image and obtained by applying the orbital model to a series of control points of known geographical coordinates. This procedure offers results which have an error of around one pixel.
