卫星编队飞行中的相对轨道构形 - Autonomous relative orbit determination for satellite formation flying on basis of orbit element differences
基于轨道根数差的卫星编队自主定轨研究 - Case 1 : when there is no relative measurement , each satellite uses its own on - board attitude sensors to determine its attitude , and exchange the information through the communication link between formation satellites , and then the relative attitude is determined through simple mathematical operation . case 2 : based on the range measurements of gps like sensors , using two - point measurement of the relative orbit state to establish relative orbit and attitude kinematics and measuring equations . and state estimation is achieved through the extended kalman filter technology and unscented kalman filter technology , respectively
方案一,在星间无相对测量时,由卫星自身携带的姿态敏感器实现单星高精度姿态确定,利用星间通信链路进行信息交互,通过简单的数学计算获得星间相对姿态;方案二,利用类gps相对测量,建立了编队卫星相对轨道运动和相对姿态运动模型及相对距离测量方程,推导了两点相对轨道运动模型,设计了扩展卡尔曼滤波器及uscented卡尔曼滤波器,对相对位置、速度和姿态进行估计。 - In the dynamic method , starting from the analytical solutions of the cw equations , the flying - around orbit is proved to be an ellipse centered at the reference satellite , and its description parameters are presented , hi the kinetic method , flying - around conditions and equations in kinetic form are obtained by first order approximating , and the description parameters of the relative orbit are given
动力学方法从cw方程的解析解出发，证明了绕飞轨道是以参考卫星为中心的椭圆，定义了绕飞轨道的描述参数并给出了其表达式。运动学方法通过一阶近似，得到了运动学形式的绕飞条件和绕飞方程，给出了绕飞轨道各参数的表达式。
