摘要
Abstract
For the problem of multi-beam antenna pointing for GEO satellite, a method of precise measurement of multi⁃beam antenna pointing has been studied. In the case that the inherent coupling interference exists among transmitting channels of satellite, the principle and formula for measurement of satellite antenna pointing are deduced in detail, where orthogonal beacon signals are sent from the geosynchronous satellite to ground stations. Then the influence of various error sources on precise measurement is discussed system⁃atically. Finally the validity and feasibility of this method are demonstrated by simulations, where some streamline recommendations are also proposed to provide theoretical reference for engineering applications.关键词
