Abstract
When errors occur in a packet received from a satellite terminal device, a modulation and coding (MODCOD) value is calculated according to a result of the detection, and a calculated MODCOD value is transmitted to the satellite terminal device, so that packet loss is reduced based on the yield of actual traffic when the satellite terminal device transmits a return link packet. An occurrence of a packet error is detected by generating a first return link packet by sequentially assembling the plurality of return link packets from the satellite terminal device and performing a comparison analysis by comparing the first return link packet with a newly received second return link packet.
