Communicating with Radio – Ground Control to Major CanSat | Teach with Space T11
In brief
To understand how everyday devices like mobile phones, routers and satellites work, we need to understand what radio waves are and how we can transmit information with them. Radio communication is one of the key elements in a CanSat. All the data needed for a scientific experiment will be sent from the CanSat to a ground station via radio waves once the CanSat is launched.
