PLANETARY SYSTEM STUDYING TOOLS CAPABLE OF SIMULTANEOUSLY MEASURING TINE, SEASONS AND ALTITUDE OF SUN

摘要

PURPOSE: celestial body teaching aid is provided to the time consistently measured, term, and height and passes through the projection in consistently holding crosspoint. ;CONSTITUTION: reference surface (10) opens its hemispherical on the upper side and lower side. The timeline (21) of indicating unit instruction, line (22) solar term, the plane of reference of altitude line (23). A kind of expanding unit (30) is amplified on the outside of the upper end of the plane of reference. Projecting unit (40) is removably mounted on the expanding unit of 4 minutes outdoor scene teams. ;The 2011 of copyright KIPO submissions
