At any point, if the sun elevation or sun azimuth errors or the momentum vector error exceeds tolerances, the ACS will return to an appropriate mode in order to correct the problem.
在任何时间点，如果太阳仰角或是太阳方位角的错误或是动量向量的错误超过容忍度时，那么ACS将会为了修正此问题而回到适当的模式。
System directly calculate any point at a given moment in the sun elevation Angle, solar azimuth, solar declination Angle, the day of sunshine, year round sunshine and average annual sunshine time.
系统直接计算出任意一点在给定时刻的太阳高度角、太阳方位角、太阳赤纬角、当天日照时间、全年日照时间以及年平均日照时间等。
As expected, the measured brightness temperatures change with view zenith angle, view azimuth angle, and the Sun position.
地面亮度温度的测量值随观测天顶角、方位角和太阳位置而改变。
