Abstract: Automatic image navigation for remote sensing satellite is used to determine each image pixel’s latitude and longitude automatically.Now this method has been widely used in meteorological,oceanic,resources,environment research fields and thus contribute great social and economic benefits.In this paper,a new automatic image navigation method is introduced for remote sensing satellite based on maximum cross correlation.First,the problem description is presented.Secondly,the whole dataflow for image navigation is introduced.Thirdly,the automatic navigation adjustment model based on maximum cross correlation which is the key step of the whole image navigation is designed and implemented.Finally,the performance is given by testing data through which this method is proved to be effective and of high accuracy.

Key words: remote sensing satellite, automatic image navigation, automatic navigation adjustment model
