  • STK基础知识(1)——轨道六根数 - 知乎
    第五个参数,RAAN(right ascension of the ascending node), 升交点赤经。 也可翻译成 longitude of ascending node。 指的是卫星轨道的升交点与春分点之间的角距,通常用Ω表示,升交点赤经是在赤道面。 春分点的定义为太阳沿黄道运行中,自南向北穿越赤道时的交点。
  • Longitude of the ascending node - Wikipedia
    The angle is measured eastwards (or, as seen from the north, counterclockwise) from the FPA to the node [2][3] An alternative orbital element to the RAAN is the local time of the ascending node (LTAN), defined as the local mean time at which the spacecraft crosses the equator traveling northward

  • 升交点经度_百度百科
    升交点经度(英文:longitude of ascending node)是天文学和航天动力学中常用的轨道要素之一 [7]。 其常用缩写为 RAAN(Right Ascension of the Ascending Node),中文常译作“ 升交点赤经 ” [3-5] [8]。 在台湾地区,常称作“升交點經度” [7]。

    RAAN: Right Ascension of the Ascending Node 理解:实际上是发射到轨道升交点的,也就是Y界面画云的时候轨道上的小白点。 太阳帆很多时候一射上去就会急转弯,从垂直于轨道变成沿着轨道运行。

    The Right Ascension of the Ascending Node (RAAN) is the longitude of the point where the spacecraft crosses the equatorial plane moving from south to north The descending node is where the spacecraft drops through the equatorial plane, moving from the Northern Hemisphere to the Southern Hemisphere
