Navegação astronômica: valor histórico e aplicações

Abstract

This work was developed in order to disseminate knowledge about Celestial Navigation, showing applications of past knowledge and hundreds of years of study. The path of astronomical navigation studies came shortly after the dissemination of knowledge of astronomy in a rudimentary form, of course, but that's how the manbegan to look at the sky and wonder about issues hitherto not covered by mysticism. All this history is in chronological order. In this paper they are exposed made of various names of physics, mathematicsand astronomy. Among them, it highlights that Eratosthenes calculated simply and very accurate Earth's radius and Pedro Nunes, even without having stepped aboard a ship, contributed, and for how to navigate we have today. Several nautical instruments are cited, mentioning their functions, origin and importance, some of them very creation of Pedro Nunes. This work was also awarded with the participation of Professor LázaroCoutinho who talks about his experiences aboard the Merchant Navy ships and cites the importance of astronomical navigation knowledge, making the reader feel closer to the subject matter.
