Nano-satellite communication subsystem design and implementation

Nano-Satellites perform many tasks that couldn´t be achieved otherwise. They have many subsystems but the communication subsystem is the most important subsystems. This report shows the design and implementation of the communication subsystem of a nano-satellite following the University of Khartoum educational nano-satellite prototype standard. The design phases followed the standard development process. Off-the-shelf components were used and the On-board computer subsystem was used to control the various transmit channels within the subsystems through logic gates. Lab tests performed using the nano-satellite prototype has shown that the communication subsystem performs correctly and the mission data were successfully sent by the communication subsystem and received using the University of Khartoum ground station.
