摘要： 气象航天系统是由一个或多个航天器组成的气象系统,其基本任务是向用户提供地区性或世界范围内的气象观测信息;为了估计从气象航天系统获得信息的可靠性,文章分别对从一个或多个航天器上获得信息的可靠性进行估计,并且得到信息估计矩阵;最后,讨论了信息可靠性的下限估计值。

Abstract: Meteorological astronautical system is a meteorological systemwhich consists of one or several spacecraft.Meteorological astronautical systemprovides meteorological observation information in regions or in the world forusers.In order to estimate reliability of information obtained from meteorologicalastronautical system,reliability of information obtained from one or several spa-cecraft has been estimated respectively in this article,meanwhile informationestimation matrixes have been obtained.Finally,the estimated value of lowerlimit of credibility is discussed.
