Abstract(s)
O Projeto de Desenvolvimento apresentado nesta Dissertação surge na sequência de
contatos realizados junto da Federação Portuguesa de Vela com o objetivo de construção
de um protótipo de boias com posicionamento automático.
O objetivo deste protótipo é, de uma forma autónoma, colocar uma boia em alto mar, e que
esta se mantenha numa posição pré-definida. Para responder a tal necessidade, procurou-se
desenvolver um sistema de posicionamento autónomo com base num recetor GPS, ou seja,
que tenha a capacidade de posicionar-se de forma independente sem qualquer tipo de
controlo remoto. Os desenvolvimentos alcançados com este projeto vão servir de base a
outros projetos de investigação atualmente a decorrer no âmbito do Centro de Investigação
Naval (CINAV).
Esta dissertação de mestrado relata os procedimentos efetuados durante o desenvolvimento
do sistema de posicionamento, construção da placa de controlo e escolha de algoritmo de
posicionamento. São também descritos os testes efetuados, em piscina e rio. Por fim, são
feitas algumas considerações e sugestões, realçando os aspetos positivos e os negativos.
The Developed Project presented in this dissertation, arises from contacts made with the Portuguese Sailing Federation, with the aim of building a prototype buoy with automatic positioning. The goal of this prototype is to place a buoy at the sea, and autonomously, remain at a predefined position. To answer this need, based on a GPS receiver, it became necessary to develop an autonomous positioning system, in other words, the buoy needed the ability to position itself without any support of a remote control. The developments achieved by this project will form the basis of other research projects currently underway within the Centro de Investigação Naval (CINAV). This dissertation describes the procedures performed during the development of the positioning systems, the building of the control board and choice of the positioning algorithm. Also described are the tests performed in pool and river. To conclude, there are some considerations and suggestions, highlighting the positive and negative aspects.
