Validation of satellite image positioning accuracy is the basis of supporting the satellite operation and application.This paper carries out a test of the positioning accuracy of level 2 panchromatic image and multi spectral image with GF-1 satellite PMS sensor. The test results show that the averate positioning accuracy of PMS sensor panchromatic image is 27.9m, of which the highest accuracy of test images in plain and moun-tain area is 16.4m and 53m respectively. The average positioning accuracy of multi spectral images is 23.2m, of which the highest accuracy of test images in plain and mountain area is10m and 49.7m respectively. GF-1 sat-ellite PMS camera PAN and MSS level 2 products meet the 1?100 000 scale topographic map update require-ment, of which the precision of level 2 products with plain area can meet the 1?50 000 scale topographic map update requirement.
