CubeSat is a nanosatellite concept emerged from a paper published by Stanford University and with their low cost nature and extreme feasibility , more started researching on nano satellites. New technology emerged , paving path to many academics and small vendors to create their own CubeSat models . This nanosatellite requires a transceiver to maintain its communication between it's systems and the ground station, which helps it navigate and collects data gained from its programmed functions. This transceiver system consists mainly of a transmitter and a receiver. The transmitter manages sending data from the satellite to ground station while the receiver captures the data and instruction sent from the ground station to the satellite. These systems were built using separate digital communication devices in the beginning, with many critical limitations with respect to the space and scalability of the modules to be attached and the programmability of hardware materials and the concept of system-on -board emerged. Meanwhile, As the size of electronic devices minimized with the research conducted, FPGA (Filed Programmable Logic Array) was introduced as an architecture to be used in various applications and research needs. The reason FPGA was mention was for the fact that it provides flexibility in the designing of transceiver ed with design and prototypes implementation at a low cost competitional electronic ware and the system -on chip Concept was introduced . This research describes the development a system-on-chip transceiver model for nanosatellites which contains a single carrier . Keywords-Single Carrier, transceiver, system C, FPGA
