In order to meet requirement of real-time and high accuracy in image matching aided navigation  SSDA algorithm is used to match remote sensing image and template image coarsely  a fast and effective algorithm of remote sensing image matching based on corner detection is put forward. With the combination of rough and fine match  when the matching result is bigger than one to count absolute value sum of energy difference of characteristic point energy to realize fine match of remote sensing image and template image to locate the position of template image in remote sensing image accurately. Simulation experiment proves that the matching of a remote sensing image resolution of 1018*1530 and a template image resolution of 150*90 can be fulfilled within 2.392 second  wavelet transform is used to acquire low frequency component to realize image compression to decrease calculation work and increase matching speed. Harris corner detection algorithm is used to detect corner of remote sensing image and template image and energy of every corner is calculated  the algorithm is robust and effective  real time image navigation can be achieved. 2009 SPIE.
