摘要
论述空天环境仿真时间和空间基准,并对利用JPL历表计算行星位置和速度的方法进行详细阐述;对空天环境仿真关键技术进行深入研究,从空天环境仿真内容方面将其分为星空背景仿真、行星仿真和空天环境要素仿真3个方面,并分别进行研究加以实现。仿真效果逼真、实时性强,为研究和利用空天环境提供参考依据。
It discusses the criterion of time and space to the space environment and expatiates the method of utilizing JPL ephemeris to calculate the position and velocity of planet .And it makes a deep research of the key technology of the space environment simulation .According to the content of the space environment simulation ,it divides the space environment simulation into three parts , including space background simulation ,planet simulation and the space environment element simulation ,and realizes separately .The effect of simulation is vivid and timely ,which will provide a reference for researching and utilizing the space environment .
