This is a solar geometry training platform. Precise alignment is achieved using touch dials and sliders via quadrant, lunar illumination, noon analemma, station latitude, shadow rod, eclipse alignment, as well as azimuth, day length, twilight, declination, and angle-related questions. Each instrument comes with theoretical aids and formula explanations; completing the training unlocks the principle card and writes the observation log.
