摘　　要：太空中卫星和天体在各种引力的作用下都在一定的轨道中周期转动着,但实际的轨道是很复杂的。两行轨道数据(TLE,Two-Line-Orbital Element)由美国celestrak发明创立,用于描述太空飞行体位置和速度的表达式。卫星星历以开普勒定律的6个轨道参数之间的数学关系确定飞行体的时间、坐标、方位、速度等各项参数,具有极高的精度。卫星星历能精确计算、预测、描绘、跟踪卫星等飞行体的时间、位置、速度等运行状态,能表达天体、卫星、航天器、导弹、太空垃圾等飞行体的精确参数。Satellites and celestial bodies in space rotate periodically in a certain orbit under the action of various gravitational forces,but the actual orbit is very complicated.Two-line orbital data(TLE,Two-Line-Orbital Element)was invented and created by Celestrak in the United States to describe the expression of the position and velocity of spacecraft.The satellite ephemeris uses the mathematical relationship between the six orbital parameters of Kepler's law to determine the time,coordinates,azimuth,speed and other parameters of the fl ying body,with extremely high accuracy.The satellite ephemeris can accurately calculate,predict,describe,and track the time,position,and speed of satellites and fl ying objects;it can express the precise parameters of celestial bodies,satellites,spacecraft,missiles,and space junk.
