Detailed sequence of intelligent pointing. After completion of the preceding observation, the line of the sight (LOS) is steered to the next scheduled observation point. After the steering was stopped completely, after about 250 ms of the start of the steering, the image around the scheduled observation point is taken by the monitor camera (about 150 ms duration of). Then, the image is transferred to the processing part; the clouds are detected with about 50 ms duration). Based on these results, the cloud-free area is determined. The LOS is steered to that area (about 50 ms duration of). The next measurement starts at 650 ms after completion of the preceding observation
