The interactions between orbit altitude and the maximum revisit time are analyzed.

分析了轨道高度与最大访问间隔时间之间的关系。

At that low altitude, this orbit will not last very long, and the satellite will reenter into the Earth's atmosphere.

在低空，轨道，无法维持太久，卫星会重新进入地球大气。

Together, these incidents increased the number of objects in orbit at an altitude of 700-1, 000km by a third (see chart).

这些事故及事件使离地700 - 1000公里的轨道上运行的太空物增加了三分之一(见图表)。

The probe entered a special low-altitude orbit for about five months to allow the GRAND instrument to analyze emissions from Vesta's surface that result from collisions between cosmic ray particles and elements in the asteroid's dirt.

Alongside the HTC-made handset are an altitude and orbit control system, two propulsion setups and a Linux-based computer with a "high-speed" processor.
