Paper Abstract

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.
