Abstract :
In this paper, a new developed satellite receiver for very slow data operation and an experimental SSB→FM transponder is described. The receiver is an uplink part of the transponder that is based on a new unconventional method for Doppler shift rejection by the help of FM downlink and low SSB uplink frequency with an application of FDMA. The base advantages of the slow rate PSK31 operation, the design and measurements of the receiver with respect to high reliability and low power consumption, the transponder and a practical simulation of Doppler shift influence on a transmitted message error rate is presented. This project is apart of PCSAT2 satellite project of US Naval Academy that has to be placed on ISS.
