Metodologia para desenvolvimento de subsistemas de TT&C em CubeSats

The CubeSats concept began in 1999 as a collaboration between California Polytechnic State University and Stanford University, and today it is an accessible and widely used by educational institutions and the private sector for the development of small satellites. As these small satellites are unmanned, the Telemetry Tracking and Remote Control (TT&C) system is one of the most critical to the mission, as their failure results in its premature end. This work presents a study of the main concepts related to the TT&C system, especially with regard to minimum power and transmission speed to ensure correct and complete transmission of payload data. Posteriorly, using the concepts presented, a set of needs is elaborated for its good functioning and good integration with the other systems of a CubeSat
