| Abstract: | We discuss the source of APM＇s errors. Combining with azimuth-elevation type and antenna pedestal, an error model is established and effect of different error factors on antenna pointing accuracy are analyzed. The method provides a theoretical basis for these types antenna design precision. At the same time, concepts and methods used in the study can also be used for other multi-axis error analysis, so it has certain practical significance. |
