Abstract

The Communications Research Laboratory (CRL) has been carrying out research and development of a very low rate message communication system with an ultra-small earth station called the Attache Case Size Message Communication Terminal (AMCT). In order to minimize the size and power consumption of the AMCT, a transmission rate of 100 b/s is adopted. This is extremely low for satellite communications. As a result, the AMCT is similar in size to an attache case. In the base station, the fast Fourier transform (FFT) technique is used in order to search for a very narrow band signal from the AMCT and compensate for the frequency deviation of the signal. The experiments have been carried out through ETS-V satellite links to estimate the bit error rate (BER) and acquisition performance of this system. Also, the probability of completed message transmission is calculated using these experimental results. Based on these results, it is confirmed that a very low rate transmission system such as this system is applicable to satellite communications
