We present a qualitative analysis in a phase space to determine the longitudinal equilibrium positions on the planetary stationary orbits by applying an analytical model that considers linear gravitational perturbations. We discuss how these longitudes are related with the orientation of the planetary principal inertia axes with respect to their Prime Meridians, and then we use this determination to derive their positions with respect to the International Celestial Reference Frame. Finally, a numerical analysis of the non-linear effects of the gravitational fields on the equilibrium point locations is developed and their correlation with gravity field anomalies shown. 相似文献

随着反舰导弹武器系统的快速发展,舰船反导拦截系统迫切需要对其进行追踪与防御。而作为近程防御探测设备,红外探测器需要为拦截系统提供目标指示。研究了反舰导弹的红外视景仿真,使用Creator软件完成对导弹弹体的几何建模;使用Vega Prime软件完成视景配置;通过C++语言应用程序接口API调用ACF文件完成红外图像的生成;构建了导弹飞行驱动模块、尾焰模块、红外图像生成模块和气象仿真模块,并生成了典型导弹攻击航路的红外图像序列,为目标指示、识别和跟踪提供了仿真技术思路,在红外视景仿真开发实现上具有一定实用性。 相似文献
