Our satelite was down, ok?

我们的卫星被打掉了，好么？

Each of the satelite is contantly sending out the signals.

每个卫星都能单独发射讯号。

The satelite was launched into the orbit around the earth.

卫星被发射到围绕地球运转的轨道。

The map looks like an overlay, not an image, so is this the satelite moving then being corrected?

这个图看起来像是叠加的，而不是一个图片，所以这是因为卫星在移动中（出了一个小差错）然后又被修正了吗？

There are lots of mixed pixels in the low spatial resolution remote sensing images due to the limitation of the resolution of the satelite sensor.

由于传感器的分辨率的限制，在低空间分辨率遥感图像中存在着大量的混合像元。
