Device for measuring geographical distances for use in detecting movement of the Earth's crust and continental plates is based on a simple portable arrangement of a 3 meter high rod with a 4 meter long base

摘要

Device for measuring geographical separations and heights consists of a 3 meter high rod and a 4 meter high base with the two elements at right angles to each other. The device can be used to determine the position of the sun and then used to determine the distance between two points or the difference in altitude between two points. Calculations are based on super-potentials.
