摘要
在低轨卫星上安装星载GPS接收机、为卫星提供位置速度与轨道参数的应用已越来越广泛。星载接收机实时定位的位置误差和速度误差会对计算出的卫星轨道根数产生影响。本文用模拟数据分析了定位误差对卫星轨道根数的影响。结果表明:速度误差对轨道根数的影响远大于位置误差对轨道根数的影响。

The errors of the ained from spaceborne GPS rec influence on satellite＇ s orbital error could be far greater than eiver would degrade the accuracy of orbital elements with simulated data. The result s that of position error on orbital elements. installed in low-orbit satellite real-time position and velocity elements. This paper analyzed howed that the effect of veloc-ity error could be far greater than that of position error on orbital elements.
