摘要:

为了模拟同步卫星在外太空的飞行状态,建设先进的同步卫星模拟仿真系统对于卫星的研制与性能分析有着重要的意义；由于卫星是在特定的轨道上飞行,所以对卫星轨道的绘制建模是卫星模拟仿真系统开发中关键的一环；在这篇文章中介绍了同步卫星与地面观察站通信过程中的扫描视锥与同步卫星运行轨道的绘制算法,重点探讨了基于OpenGL基本矢量图元的绘制以及利用世界坐标系和向量的方法对在绘制过程中所需数据的求解过程；分析了根据同步卫星的运行姿态与其所在轨道的位置来确定同步卫星扫描视锥的角度；最后通过一个虚拟世界的3D引擎验证算法的可行性与绘制效果。

Abstract:

In order to simulate the flight status of synchronous satellites in outer space,developing an advanced simulation system of synchronous satellite for the research and performance analysis of satellite has important significance;Because the satellite is flying in a certain orbit,the modeling and rendering of the satellite orbit is a kay link in the development of the satellite simulation system;In this paper, we introduce the mapping algorithm of the scanning cone and the running track of the remote sensing satellite in the communication between the remote sensing satellite and the ground station; Based on the OpenGL basic vector graphics rendering and the use of the world coordinate system and vector method in the drawing process of the required data; Analysis of the angle of the remote sensing satellite scanning cone angle based on the position of the remote sensing satellite;Finally,the feasibility and rendering results of the algorithm are verified by a virtual world 3D engine.
