“…Later, the SIMCS simulator was built to comply with the CBERS-1 (China-Brazil Earth Resource Satellite), used to support operators' training activities and operations details, such as attitude and orbit control telecommands. The FBMSIM simulator was designed to support operations team training for the French-Brazilian scientific micro-satellite [5] where one of the challenges consisted into specifying how the satellite behavior is represented in the final software product. It is hard to find a common language, understandable and acceptable by every stakeholder, and yet powerful enough to describe the satellite behavior [6].…”

Due to its large territory, Brazil relies on space systems to perform a myriad of supporting activities. Space systems design requires strong modeling and simulations techniques for achieving high performance. This article describes the development of a goal-driven user interface (UI) for spacecraft distributed simulations using a service oriented paradigm and supporting different space missions. From usability problems with traditional simulators UIs, described by satellite subsystem design engineers, this work proposes three dimensional visualization, natural interaction techniques, virtual and augmented reality as well as interaction with touch-screen and gesture recognitions. This research uses an open source C/C++ toolkit, designed to provide interactivity, networking and scripting capabilities for simulator developers, this facilitates in providing specific input or output driver engines. Finally, some further developments are described for future work.

On-board software is one of the most important developers use a graphical environment enabling them to parts of satellite. It composed of software modules which design software structure with graphical components Instead of are responsible of meeting the satellite functionalities. In writing source code. Then the tool can create related source addition there is an OS which provides software and code and user can develop and debug it. The software hardware resources for the software modules through generated in TEV can be transferred to real platforms with services. This paper deals with simulating one of these OS Virtuoso OS. The main Emphasis of this tool is using a visual called virtuoso. It introduces a new simulated environment environment for design, implementation and test of sample allow us to run the Software on PC as a general purpose software. Therefore it is very useful for educational purpose. hardware. We called this VirSim.

“…In this work, we are interested in a software tool that supports the operations phase of satellites, called Operational Simulator (OS). This simulator can be used before the launch of the satellite, to validate the ground control system, to train the ground operators and to test the operation plans, before applying them to the real system in orbit [2][3][4].…”

In space systems engineering, the Operational Simulator (OS) is a computational tool that can be used to test and validate the ground control system, to train the flight control operators, and to support the operation of spacecrafts. In order to accomplish these tasks, the OS must produce data of all the spacecraft subsystems in real-time. Among these subsystems, the thermal control subsystem is one of the most demanding in terms of computational cost. In this work we use Artificial Neural Networks (ANN) to learn the thermal behavior of a simple CubeSat model, generated by a thermal analysis software, and then apply it to reproduce that behavior and to generalize for scenarios not presented during training. The results show that the ANNs can simulate the temperatures of the CubeSat with good fidelity and very low computational cost.
