SATUM-modulul de captare, procesare digitală şi transmisiune în bandă ultra largă a imaginilor Terrei

Abstract

The main units of image capturer, error-correcting coder and digital phase shiftkeying modulator of the university nano-satellite, called SATUM, are presented and described in this article. This SATUM subsystem is implemented on 3 printed circuit boards of 100-by-100 mm size. It allows to capture the Terra color images of 4,2 Mpx size and transmit them in real time to the ground station by one image per second. The ISM-band unlicensed frequencies are used for images transmission.
