摘要: 摘要: 针对基于星间相对测量的相对导航算法中由测量方程将相对轨道拟平根数转化为相对位置过程导致的模型非线性,提出一种基于约化相对轨道拟平根数的卫星编队导航方法.该方法通过编队卫星之间一段时间的切向漂移估计半长轴偏差,合理处理半长轴偏差对双星相对动力学的影响,克服了模型线性化造成的误差,能够实现长期稳定的高精度卫星编队导航.

Abstract: Abstract:Based on intersatellite measurement and reduced relative orbit elements of satellites, an improved approach of formation navigation is investigated. The traditional navigation algorithm transforms the relative orbit elements into the relative position by measuring equations, which results in nonlinearity of the navigation model. In the improved approach, the difference of semiaxis is estimated via the excursion in alongtrack. The problem of linearization error can be solved by using the difference of semiaxis, which has an important influence on relative dynamic of satellites. The method can realize a longterm stable and highprecision navigation of satellites formation.

Key words: Keywords:satellites formation, longterm stabilization;relative navigation, reduced relative orbit elements, difference of semiaxis
