Tacking Mode (Calculation mode and Sun sensor mode)

Skyradiometer can track sun position with auto-switching calculation and sun sensor mode. Based on the data
(latitude, longitude, time) it can keep sun tracking. This is the so called calculation mode. In addition, skyradiometer
increase tracking accuracy with using sun sensor. Sun sensor can respond if it receive sun light within 5 degree.

During sun sensor receive threshold value, skyradiometer keep tracking with sun sensor mode. In other words user
is required tracker is mounted at direction within at least 5 degree from real sun position. Like next picture if user

cover sun sensor by hand and skyradiometer move position, it means there is room to improve the accuracy between
calculation mode and sun sensor mode. In this case user is required to bring up the tracker base and turn little its
direction clockwise or counterclockwise so that tracker changes its tracking point with very few angle.
