Asia-Pacific Optical Satellite Observation System (APOSOS) is based on members of Asia-Pacific Space Cooperation Organization (APSCO). Its aim is to develop a regional or even global satellite tracking system basically composed of optical trackers. The system will be used to track objects of interest or space-debris for the safety of spacecraft launch mission or the intactness of operational satellites. APOSOS is composed of Asia-Pacific optical satellite observation center, APSCO member state node, sub-node and observation telescope. Asia-Pacific optical satellite observation center manage the whole observation network. Every member state node answers for the organization of observation with their country’s facility according to the observation plan released by observation center. The sub-node transmits observational data to corresponding member state node first. Then the member state node transmits the data summarized to the observation center. This paper will briefly introduce the APOSOS project first and present the design of computer communication and network in APOSOS project in detail.
