Communication System for Nanosatellite Earth Observation

Abstract

This paper proposes a communication system for nanosatellite Earth observation preliminary design technique as useful tools for managing and improving various aspects of regional and national resources. Has been estimated and proposed a design process for the low Earth orbit nanosatellite communication system. In proposed paper on basis of structural optimization technique have been formulated and solved next goals: reviewed Earth observation systems and studied their design parameters, analyzed the on-board antennas design background and provided analytical estimations, such as design a passband quadrature phase shift keying transmitter and receiver in Simulink, was obtained a bit error rate curves by using a Simulink / 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 according contemporary design concept. All this allows to propose innovative communication system design techniques applied for the nanosatellite category.
