TO FIND THE TRUE DIRECTION TO A DISTANT PLACE (OBJECT) BY THE OBSERVATION OF THE SUN AT A PRE-DETERMINED TIME FOR THE DAY OF OBSERVATION

摘要

In matters of finding the direction from one place to another having a very long distancein between them, we can use several methods including compasses, maps and our senses.But the directions found in this manner will be approximate ones only, and may not givethe true direction because of the earth's spherical shape. In such a situation, we can use avery reliable object, the sun, for the purpose of finding the direction as accurately as wewant by having calculated the times of observation related to the corresponding dates,knowing the latitudes and longitudes of the places concerned.
