There is a hypothetical necessity of Brazilian National Defense as for the implementation of RPAS (Remotely Piloted Aircraft Systems), commonly known as drones, in their tactical and strategic operations. Even the RPAS providing countless applications and even replacing the use of conventional aircraft, piloted by onboard pilots, was identified a l...
Conference Paper
The earlier phases of any product development greatly influence its life cycle, especially in the aerospace field. Therefore, precise requirements are critical for good acquisition/development contract execution. Firstly, this study has made use of OPM (Object Process Methodology) to model the current Brazilian Air Force Policy for aerospace produc...

The development of a system begins with the comprehension of its mission and the gathering of the expectations and needs of all involved parties. Transforming these into a set of complete and coherent requirements is essential for the mission's success. That is even more true in the space systems' context due to the high costs associated with tardi...

How did two planets of the Solar System with similar sizes, density, and distance to the Sun take so different ways of evolution? The contribution of this work consists in the analysis of the nominal Venus observation orbits and SAR techniques that can be applied for VERITAS (NASA) and Envision mission (ESA) to optimize the acquired data.

This paper aims to describe the structure of a framework for an automated pico and nanosatellite model validation, using commercial tools. It was proposed that the models are as granular as in the verification plans (it is not possible to test internal behaviors from a black box artifact), so, each model represent an element in a unique file and a...

This work describes an initiative to a serious game-like user interface used for an operational satellite simulator. The simulator is part of a simulation architecture intended to provide a richer behavior analysis tool set to the real artefact, as a source of possible behaviors scenarios. In order to interact with the underlying behaviour, the use...
