Abstract: PURPOSE: A forward link adaptive transmission device and a method thereof for satellite communication are provided to increase availability of a forward link by determining a modulation and a code rate suitable for channel of each terminal using forward link SNR(Signal to Noise Ratio) information. CONSTITUTION: A transmission device(100) includes a channel estimation unit(110), a control unit(120), a routing unit(130), and a modulation unit(140). The channel estimation unit estimates a channel state by terminal by receiving an SNR from terminals. The control unit confirms predetermined modulation and code rates corresponding to a predetermined section according to the channel state and confirms the modulation and code rate according to the channel state by terminal. The routing unit receives traffic data, confirms a receiving target of the traffic data and classifies the traffic data by the modulation and code rate. The modulation unit modulates the traffic data classified by the predetermined modulation and code rate with a modulation method corresponding to the each modulation and code rate.

Abstract: The present invention relates to a satellite communication system and method based on a digital video broadcasting-return channel via satellite (DVB-RCS), which includes a district center and at least one very small aperture terminal having a first satellite very small aperture terminal and a second very small aperture terminal. When the district center receives a logon request from the second very small aperture terminal, the district center determines whether the first very small aperture terminal operates in a normal condition and permits the second very small aperture terminal to logon if the first very small aperture terminal does not operate in normal condition.
