The optimization methods of information transmission in satellite communication systems are passing in review. First method concludes in finding optimal length of transmitting data packet. Receiver searches errors in received data packet, for example using checksum, which contains in service part of data packet. If receiver detects at least one error, it reports command to resend data packet. Automatic error correction by decoder is not featured in this article. On one hand, the bigger length of data packet, the bigger probability of wrong transmission of at least one bit of information. On the other hand, transmission of small data packet is not effective because a quite big part of packet consists of service part. Optimal length of transmitting data packet depends of bit error ratio, technical speed of transmission and delay in receiver. Second method found on real inequality of transmitting data traffics Ground – Satellite and Satellite – Ground. In this case one of up or down lines, which are using different carrying frequencies, is not in use for some time, especially when speech traffic is transmitting in telephone conversation. Reserve of increasing performance consists of decreasing occupation time of channel by using free line to transmit the rest bigger piece of packet in second channel.
