APPARATUS AND METHOD OF GENERATING NETWORK CLOCK REFERENCE (NCR) PACKET FOR ACQUIRING NETWORK SYNCHRONIZATION IN TWO-WAY SATELLITE COMMUNICATION SYSTEM

摘要

An apparatus for generating a network clock reference (NCR) packet for acquiring network synchronization between satellite communication devices in two-way satellite communication system, the apparatus including a clock reference determiner configured to determine an NCR based on a trigger signal with respect to a start of a first frame, a synchronization compensator configured to determine a synchronization compensation value by reflecting frame variable length information from the first frame to a second frame into which an NCR packet is to be inserted, and a packet generator configured to generate the NCR packet by combining the NCR and the synchronization compensation value, is provided.
