510			_aSatellites have become the most predominant part of modern information transmission systems. They have played a pivotal role in development and advancement of technologies such as GPS Navigation, Disaster Management Systems, Telemedicine services, Tele-education services, TV Broadcasting services etc. With advancements in these technologies there is a need for robust communication system that is capable of delivering stable and reliable data continually with constraints in hardware resources, communication bandwidth, transmission power and channel nonlinearity. To meet these requirements selection of precise modulation scheme is essential. This paper proposes the design and implementation of a reconfigurable modulator which is capable of performing modulation schemes that can effectively counter the limitations listed above. The proposed modulator can perform modulation schemes such as Frequency Shift Keying (FSK), Minimum Shift Keying (MSK), Offset Quadrature Phase Shift Keying (OQPSK
