Does an Analemma visualize the Earth's actual orbit around the sun?

[QUOTE="tech99, post: 6549527, member: 477979"] The analemma shows the Equation of Time and the Declination of the Sun through the year. It can be considered as portraying the slow movement of the Sun's Geographical position on the Earth's surface each day. By knowing the Sun's GP and by measuring its altitude with a sextant, we can draw a circle passing through our (unknown) position. By repeating this measurement a few hours later we can obtain another circle, and where they cross is our position. This is the basic principle of position finding when not at noon. [/QUOTE]
