摘　　要：随着航天技术水平的不断提高，卫星平台逐步向小型化、低成本发展，卫星编队飞行技术在该过程中日益成熟，通过卫星编队可以实现较多复杂功能。国外在此领域已有多个成功案例，如美德合作研制的重力和气候实验卫星（GRACE—1，2）、德国Tandem—TerraSAR编队卫星等；国内也取得了较快发展，如天宫二号伴随小卫星试验等。本文基于CW方程对卫星编队飞行相对运动关系，进行了定量和定性研究，分析了CW方程的使用约束条件及解的初始条件对编队卫星形成稳定状态构形的影响情况，并通过实例进行了结果验证，取得了较好结果。With the improvement of aerospace technology, satellite platform becomes smaller and low-cost. In the process, satellite formation flying technology has been increasingly maturer and able to perform more complicated functions. Some success- ful examples in this field have been furnished by foreign countries, such as the gravity and climate experimental satellites GRACEd and 2 developed by United States and Germany, and Tandem-Terra SAR satellites developed by Germany. China has also made some achievements, taking the small companion satellite formation flying exercise of Tiangong-2 space laboratory as an example. In this paper, the relative motion relationship of satellite formation is studied quantitatively and qualitatively based on CW equations, and the constraint conditions of equations and the influence of initial conditions of the solution on the stability of formation satellite are analyzed. The results are verified by an example and turn out to be fairly good.
