2012年12月13日,嫦娥二号卫星近距离飞越近地小行星“图塔蒂斯”并获取清晰影像,至此,嫦娥二号卫星在成功完成工程任务的基础上,圆满完成了4个阶段拓展任务,为我国深空探测领域的发展积累了丰富的理论和工程经验,同时使我国成为第4个具有小行星探测能力的国家.嫦娥二号飞行控制支持系统对卫星飞控策略的制定、仿真验证、效果预示和设计方案优化起到了关键作用.本文介绍了基于数字仿真的嫦娥二号地面飞控支持系统的设计思路和整体功能,并对其中自适应轨道动力学模型、星敏感器星图构型分析和视景仿真等关键技术进行了介绍,针对卫星飞控难度大、不可实时测控、任务窗口唯一等特点,提出了一种地面仿真支持技术方法.
On December 13, 2012, Chang’e II satellite flew over the near-Earth asteroid “Tu Tatisi” at a close distance and obtained a clear image. At this point, Chang’e II satellite successfully completed its successful completion of the engineering mission 4 stages of development tasks for the development of deep space exploration in our country has accumulated rich theoretical and engineering experience, while making our country as the fourth asteroid exploration capability of the country. Chang’e II flight control support system for satellite flight control strategy The simulation verification, the effect prediction and the optimization of the design scheme play a key role.This paper introduces the design and overall function of the Chang’e II ground flight control system based on digital simulation, and introduces the adaptive orbit dynamics model, the star Sensor star chart configuration analysis and visual simulation and other key technologies are introduced. Aimed at the difficulty of satellite flight control, the real-time measurement and control is not available and the task window is unique, a ground support simulation method is proposed.
