La navegación astronómica : Método por rectas diferenciométricas tangentes y método de Dowes.

Abstract

El presente trabajo hace un repaso de los fundamentos y los conceptos básicos de la navegación astronómica y de la teoría del sextante, explicando también los diferentes ajustes que se le hacen al sextante para su correcto funcionamiento y la importancia de estos. A continuación se resuelven una serie de ejercicios realizados durante las navegaciones oceánicas por medio de 3 métodos distintos: el método de rectas de altura tradicional Saint Hilaire, el método por rectas diferenciométricas tangentes y el método de Dowes. Cada uno de ellos se trata detenidamente con un ejercicio explicativo y se incluyen 4 ejercicios resueltos. Por último se realiza un análisis de los resultados obtenidos y una comparación de los diferentes métodos. Se concluye con que, si bien cualquiera de los métodos es perfectamente válido, la mejor precisión la obtendremos con el método de las rectas diferenciométricas tangentes, ya que fue ideado con el fin de reducir los errores al mínimo. El método menos preciso es el método de Dowes, pero tiene la ventaja de que no requiere una situación de estima previa.
