As an intern at Embraer I participated in the development of a simulation environment in C that paired different secure endpoints, with the objective of establishing communication between a ground control station(GVS) and an unmanned aerial vehicle(UAV) using different radios and satellites.Through this we were able to add a tool for future simulation applications for the company. Learning about the protocol of security of both the computer side and aircrafts side was a great experience and helped me understand furthermore the workings of a successful company such as Embraer.
