On the basis of mean orbit concept, a fast algorithm for the prediction of LEO satellite passes and image opportunity is presented.
在引入平均轨道概念的基础上，提出了一种针对低轨道卫星的过顶与成像区域时间的快速预报算法。
I mean, isn't it more sensible to think that a smaller heavenly body would orbit a larger one, rather than the opposite?
我的意思是，如果一个更小的天体会绕一个更大的天体运行，而不是大的围着小的转，不是更合理吗？
It orbits its star every 4.7 days, in a moderately elliptical orbit at a mean distance of only 0.04 AU (one tenth of Mercury's distance from the sun).
它每4.7天环绕恒星一周，其轨道为一个适度的椭圆，平均距离仅0.04个天文单位(为水星距太阳的十分之一)。
If we take "space" to mean a low Earth orbit such as the one traveled by the space Shuttle roughly 160 to 350 miles above Earth, the Great Wall claim fails twice.
如果我们把“太空”定义为较低的地球轨道，比如大概距地面高度160至350公里航天飞机飞行的轨道，有两点可以揭穿长城传言。
But no, this doesn't mean that Earth's inclination has changed or that we are off our orbit or that the Sun has changed its position.
不过这并不意味着地球的偏角发生了变化，也不意味着我们偏离了轨道，更不意味着太阳挪地方了。
Building one would mean lowering a cable from a satellite in a geosynchronous orbit above the Earth's equator while deploying a counterbalancing cable out into space.
建造这样一个设备将意味着，会架设一条在地球同步轨道卫星下方，地球赤道上方的电缆，同时还可以在太空中有效利用这个对重平衡电缆。
On the basis of analytical orbit theory, the state transition matrix from mean to transient orbit errors was put forward.
在解析轨道理论基础上，给出了平均轨道要素偏差到瞬时轨道要素偏差的状态转移矩阵。
One worry is that constellations of nanosats will mean a big increase in space junk; but, operating in low-Earth orbit, they burn up on re-entry after a year or so.
其中一个担忧是一群微型卫星就意味着太空垃圾大量增加，但是，如果在近地轨道运行，这些卫星就会烧掉或者一年后重新进入轨道。
As shown, the earth's mean radius is about 6378 km, while the altitude and orbit radius of a GSO satellite is approximately equal to 35786 km and 42164 km respectively.
由静止卫星的轨道位置示意图可见，地球的平均半径约为6378公里，静止卫星的轨道高度约为35786公里，轨道半径约为42,164公里。
The same code can also be used to compute spin-orbit coupling using a effective one-electron so Hamiltonian and so called Atomic Mean Field Integrals (AMFI).
相同的代码也可以用来计算自旋轨道耦合的有效利用单电子哈密顿和所谓的SO原子平均场积分(AMFI)。
