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.
