摘要
利用IGS精密星历提供的GPS卫星坐标,采用切比雪夫多项式对GPS卫星坐标进行拟合,最终在MFC的环境中运用OpenGL实现对GPS卫星轨道的三维可视化。通过对GPS卫星轨道的可视化,为GPS卫星状态的监测提供了更加直观的工具,对以后卫星导航定位的研究具有重要的意义。
In this paper, we use Chebyshev polynomial to fit the GPS satellites＇ coordinates provided by IGS precise ephemeris. Finally, we use OpenGL for visualizing the GPS satellites＇ orbit in the environment of MFC. Visualizing the GPS satellites＇ orbit provides a more intuitive tool for monitoring GPS satellites＇ states and has great significance to GPS navigation later.
