Results of the development of an automatic navigation method for AVHRR/3 images obtained during a full receiving session of the European MetOp satellites are presented. The method is based on SGP4 orbital motion model (with propagation TLE telegrams) and a mathematical model of MetOp/AVHRR physical image formation. The last model takes into account the main attitude control mode of the MetOp satellite platform (yaw steering) and scanning geometry of the Earth surface. Using the method of ground control points (GCPs), FOV (Field Of View) nominal values were refined for AVHRR/3 radiometers mounted on MetOp-A and MetOp-B satellites. Pixel navigation accuracy is achieved by computing satellite attitude angles (roll, pitch and yaw) based on GCPs that are automatically defined in an image. If the GCPs configuration on the image does not allow restoring a full set of navigation correction parameters, then navigation attitude forecasting is performed. An approach to navigation forecasting is suggested based on the calculated MetOp attitude angles dependence on the track location of satellite orbits. The approbation results of the new navigation method are presented and discussed for long series of MetOp/AVHRR data received at the Center for Regional Satellite Monitoring of Environment of the Far-Eastern Branch of the Russian Academy of Sciences (CRSME FEB RAS). The navigation results by the proposed method are presented in an RGB-image gallery at the CRSME FEB RAS website (
