Figure 1 - orbits of geostationary satellites and polar - orbiting satellites 图一地球同步气象卫星和极地轨道气象卫星的轨迹。
As they move , they obtain images of different parts of the earth 极地轨道卫星经两极上空环绕地球运行，期间不断拍摄地球上不同的地区。
Images from polar - orbiting weather satellites are also useful in discerning sandstorm and dust 极地轨道天气卫星的图像对辨识沙尘暴很有帮助。

Table 1 comparison of the mode of operation between polar - orbiting weather satellites and geostationary weather satellites 表一极地轨道天气卫星与地球同步天气卫星运作模式的比较
Terra and aqua are polar - orbiting satellites of the earth observing system operated by the u . s . national aeronautics and space administration nasa Terra及aqua属于美国太空总署地球观测系统的两颗极地轨道卫星。
Polar - orbiting satellites are low - flying satellites circling the earth in a nearly north - south orbit , at several hundred kilometers above the earth 极地轨道气象卫星以大致南北方向环绕地球运行。它的轨迹离地面约数百公里。
