摘　　要：分布式卫星群是通过一组编队飞行的小卫星协同工作来完成某一特定任务的 ,其功能和可靠性远远超过一颗单独的大卫星 ,因而具有高的性能 /价格比。这一概念于 2 0世纪 90年代中期提出后 ,引起了国内外的广泛重视 ,人们开始探索利用多颗小卫星进行编队飞行的可行性及其潜在的应用领域[1～ 3 ] 。提出了最优测高误差的轨道设计方法 ,并以 3颗编队小卫星为例 ,进行了定量分析。Distributed satellites are clusters of small satellites that cooperate to accomplish some special space missions, and their functions and reliability are far beyond a single larger satellite. Since the concept was formulated, many research efforts for seeking the possibility of using a group of small satellites to perform mission functions have been made. This paper presents a method of optimal orbit design for topographic elevation measurement, and makes quantitative analysis for three small satellites flying in formation.\;
