When the satellite was swinging and taking lateral imaging
the TDI CCD pixel photovoltaic charge purses transferred velocity not matched with the image motion velocity. According to the requirement of high-resolution satellite which was taking lateral imaging at a low orbit
the factors that bring about the unmatched phenomenon were analysed
inclusive of the Earth's rotation
the Earth curvature
satellite attitude change
measurement error and the installation error
etc. Image motion errors caused by various factors were analysed and solved
and the different characters of image motion errors were synthesized. Finally
the total errors on the impact of imaging system MTF was analyzed. 2009 IEEE.

In order to ascertain the effects of main errors of alt-alt photoelectric telescope on measurement accuracy
orientation error is analyzed.For analyzing optical
mechanical and electrical errors from measured target to telescope picture
we construct 7 coordinates such as:the earth's core coordinate
alt-alt coordinate
etc.
carry through 21 times coordinate transformation
form measuring equation with 26 variables. and we utilize Monte Carlo method to calculate the orientation error
analyze the effects of errors upon pointing. The result indicates that the measuring error standard deviation of alt-alt telescope is minimum value about 10? at the zenith zone. and the deviation increases with the rotation angles of longitude and latitude axes. The model and the method not only can analyze and synthesize the main errors
but also provide a reference to the whole design. 2009 SPIE.
