本文采用系统工程设计概念评比自旋稳定通信卫星和三轴稳定通信卫星总体方案的综合性能。文中以功能、费用、时间、可靠性和适应性五个目标函数组成多目标函数作为评比准则。为了获得定量分析结果,文中以设计一颗具有十六部通信转发器的国内通信卫星为例,计算了两种方案的多目标函数。通过比较,得出了三轴稳定卫星方案优于自旋稳定卫星方案的结论,为总体方案选择提供了依据。
In this paper, the overall performance of the overall program of the spin-stable communication satellite and the three-axis stable communication satellite is evaluated using the concepts of system engineering design. In this paper, the multi-objective function is composed of five objective functions: function, cost, time, reliability and adaptability. In order to get the result of quantitative analysis, a multi-objective function of two schemes is calculated by taking a domestic communication satellite with 16 transponders as an example. Through the comparison, the conclusion that the three-axis stable satellite scheme is superior to the spin-stable satellite scheme is obtained, which provides the basis for the overall scheme selection.
