Design and simulation of Demodulator Based BELL-202 standard for NanoSatellite Communication Sub-system

In recent years a trend of using CubeSat-class nanosatellites for commercial and scientific missions has taken the lead; this is due to the advantage of the available and low-cost products on the market without need for a large development and infrastructure investments. On our behalf, the advanced approach is to build a CubeSat platform dedicated to academic and engineering training on the different satellite subsystems, including development of a transponder based on products and software/hardware solutions accessible to the research and academic community in order to promote its use to engage in cross-team development on the basis of this platform and allowing the aggregation of a know-how. In this context, the work presented in this paper, handles partly the problematic by a proposal of the communication system design, intended to be integrated on our platform; with a particular focus on the implementation of an FSK modulator based on the Bell 202 standard. The reported development project will include simulations, implantation and the validation tests performed to achieve our first prototype.
