Abstract An automatic AVHRR navigation method has been tested using ARGOS or TBUS orbital elements as input data. Satisfactory results have been obtained on 16 NOAA-9 and NOAA-10 orbits between 19 June 1988 and 26 September 1988: a mean error of 3·5km and a standard deviation of this error of 1·2km with ARGOS, a mean error of 2·3km and a standard deviation of 0·6km with TBUS. The positioning error consists of a pixelerror which is systematic for each satellite (−1·6 pixels for NOAA-9 and 2·0 pixels for NOAA-10) and a variable line error which is mainly due to the positioning error of the satellite on its trajectory.
