Abstract :
The block diagrams of the digital image processing and transmission subsystem are presented. CMOS-sensor for image capture is used. The matroid correcting codes and coded modulation are applied. Simulink-model of the imager is elaborated, which allows determining the coding gain, equal to 5.4 dB, for admissible error probability, equal to 10-6. This coding gain allows decreasing the power consumption of the high-frequency transmitter of micro-satellite in 3.46 times.
