%X This paper proposes a communication system for nanosatellite Earth observa-tion preliminary design technique as useful tools for managing and improving various aspects of regional and national resources. Under analysis was pro-posed a design process for the low Earth orbit nanosatellite communication system. In proposed paper have been formulated and solved next goals: re-viewed Earth observation systems and studied their design parameters, ana-lyzed the on-board antennas design background and provided analytical esti-mations, such as design a passband quadrature phase shift keying transmitter and receiver in Simulink, was obtained a bit error rate curves by using a Sim-ulink/MathWorks, generated an offset quadrature phase shift keying waveform and investigated their characteristics, observed and analyzed the diagrams, constellation, and the signal trajectories of quadrature phase shift keying ac-cording contemporary design concept. As a result, this allows to propose in-novative communication system design techniques applied for the nanosatel-lite category.
