Abstract
Catastrophic forest fires have been increasingly frequent. In Brazil, the number of fires resulting from human action has increased considerably in recent years for several reasons, including the preparation of plantations, deforestation, clearing of pastures, land disputes and social protests. When the fire is detected early, it is easier to make fire control decisions and, in this way, the use of available resources is optimized and alerts the public in general. Given the importance of using remote sensing technology by satellites for the monitoring and preservation of natural resources, the current project aimed to carry out the conceptual project of the Classic FireSat mission applied to the monitoring of forest fires in Northeast Brazil. The Space Mission Analysis and Design (SMAD) process was used to define the requirements and restrictions of the mission. Studies of the location and the ways of fire identification were carried out. In addition, the final orbit design was conceived using the STK software, it was decided to use a sun synchronous orbit. Thereby, the altitude of the satellite was established as 850 km, with an inclination of 98.82 °. A preliminary dimensioning of the propulsion subsystems, determination of attitude control, management of the onboard equipment, communications and energy was carried out. There was a need to iterate the design process several times, as the phases of the project progressed. It presented a consistent theoretical basis that allows an initial estimate for projects that aim to meet the same objectives. It was demonstrated that the proposed project is adequate and feasible for the purposes of a preliminary mission design, since the results are consistent with the literature and real applications, including components available on the market.
