heavens-above网站上有了神六的轨道根数了

是的，我也看到了，比我的预测晚了两个小时呢。

楼主那有轨道根数！只是坐标而已！
骗我！

你知不知道什么是轨道根数啊？是倾角、偏心率等数据！

The orbit data is extracted from the following two-line orbital elements,

1 28879U 05040A   05285.74103987  .00051367  00000-0  28191-3 0    34
2 28879 042.4132 023.4657 0006242 184.9829 305.2717 15.78913919    79

Epoch (UTC):  5:47:06 PM, Wednesday, October 12, 2005
Eccentricity:  0.0006242
Inclination:  042.4132°
Perigee Height:  329 km
Apogee Height:  338 km
Right Ascension of Ascending Node:  023.4657°
Argument of Perigee:  184.9829°
Revolutions per Day:  15.78913919
Mean Anomaly at Epoch:  305.2717°
Orbit Number at Epoch:  7


The dashed part of the orbit path shows where the satellite is in the earth's shadow, and the full part is where it is sunlit.

我只看懂这几个：

Eccentricity:  0.0006242
Inclination:  042.4132°
Perigee Height:  329 km
Apogee Height:  338 km

偏心率：0.0006242
轨道倾角：042.4132°
近地点高度：329 km
远地点高度：338 km

靠！不全啊！少了很多数据！

好东西
