Abstract
In order to meet the requirements of the antenna beam pointing and the reformation of antenna coverage pattern in orbit, more and more satellites are equipped with the function of the antenna beam pointing adjustment. This paper discusses one kind of fine adjustment antenna pointing mechanism. Firstly, the life of this mechanism is evaluated by the accumulative wear out method, and then the life test of this mechanism is proposed by using the thermal vacuum accelerated life test method.关键词
