摘　　要：当面质比不同的主从卫星在近地轨道上作编队飞行时,大气阻力摄动和J2项摄动就成为影响编队队形的两个最主要的因素,这样描述相对运动的状态转移方程必须考虑这两项摄动。该文利用相对轨道要素法推导了包含J2项摄动和大气阻力摄动参考轨道为椭圆的卫星编队相对运动较精确的状态转移方程。当主从卫星的面质比相等时大气阻力摄动对卫星编队队形的影响很小而可以忽略,这样上面的状态转移方程可以化为更简单的形式。仿真结果表明该状态转移方程能较精确的预测编队飞行的相对运动。When satellites within a formation are of different geometry and mass, drag and J2 become the most important perturbations which effect the satellite formation. The state transition equation for the relative motion that includes the effects caused by the drag and J2 is developed using the geometry method. When satellites within a formation are of the same geometry and mass, the effects caused by drag on satellite formation become so small that it can be ignored. In this case, the state transition equation can become concisero The simulation results show that the state transition equation can predict the relative motion of satellite formation flying precisely.
