%X Based on the quantitative analysis ofthe major errorsources for NOAAAVHRRdata ,this paper presents a new navigation method .In this method ,correction oftime driftonboard and adjustmentofthe ephemeris datais carried out atthe criteria ofconstraint Least Mean Square Error;andthe spacecraftattitude deviationsis also estimated and cor rected .This navigation methodiscomprehensively considered with othercriticalelementsoflocation ,such asorbitcalcu lation ofsatellite,determination ofthe positioninformation ofeach pixel,and preciseimageregistration betweenreference image andslaveimage.By using high resolution 1 :1 ,000 ,000 digital map dataand LANDSATTMdatatoidentify GCPs (Ground Control Points) ,the geolocation accuracy ofselected GCPs can be improved . With these accurate GCPs,the geolocation accuracy of navigation for NOAAAVHRRdata can be improved to 1km in the whole image,and lessthan 1km at nadir.
