An electrical unit used to control the interim process of step scan mirror (SSM) in Atmosphere Temperature Profile Sounder (ATPS) of meteorological satellites is propounded.The control method solves the view field variation of each optical channel in its measurement period and ensures identity of 20 optical channels of ATPS in the scan measurement minor frame period of 100 msec.
