Communication System for Nanosatellite Earth Observation

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