8 Simulator Design Simulator Design Instituto Nacional de Pesquisas Espaciais 6/ 23 The software must simulate the space environment and the required subsystems in such a manner that the designers can easily see the overall operation concept of the mission, improving the level of confidence in the proposed solution. It also must show the information in a friendly way for the stakeholders. It must be adaptable to be used in different missions with minor adjustments only. It must use only free software tools, since we are planning to release the entire simulator source code to the general public. The design must be simple to build and to maintain in order to avoid high utilization of manpower.

13 Simulator Design Simulator Design Instituto Nacional de Pesquisas Espaciais 7/ 23 The simulator was divided in two parts: the simulation core and the GUI. The core is responsible to simulate everything: the space environment, the satellite subsystems, etc. The GUI is responsible to receive the information from the core and show it for the user in a friendly way.

17 Simulation Core Simulator Design Instituto Nacional de Pesquisas Espaciais 9/ 23 The simulation core was entirely coded in julia language. But, why julia? It looks like an interpreted language (Matlab users will not be afraid). It performs like a compiled language (sometimes just like C/C++). It supports metaprogramming. It can be easily embedded into C/C++ softwares. It runs on Linux, OS X, FreeBSD, and Windows. It is free.
