太阳帆航天器的轨道动力学和轨道控制研究

研究了太阳帆轨道动力学和利用太阳帆推进实现非开普勒轨道的太阳帆控制问题 ，推导了Gauss形式的太阳帆探测器密切轨道六要素微分方程，分析了太阳帆的轨道控制设 计方法，描述了适合太阳帆姿态控制的执行机构。在此理论基础上以SPORT计划作为设计实 例，并进行了设计与仿真，实现了任务要求的目标轨道。

Study on Orbit Dynamics and Control of Solar-Sail Spacecraft

In this paper, solar-sail orbit dynamics and contorl of solar-sall spacecraft which uses solar-sail propulsion method for the non-Kepler orbit were studied. Method of solar sailing trajectory design had been analyzed according to Gauss's form of the variational equations given by the thesis. The solar-sail attitude control system was described. The Solar Polar Orbit Radio Telescope misson had been designed and simulated as an example. Result of simulations shows that the desired solar polar orbit for SPORT is realizable.
