Abstract
JAXA has made an effort to build the next generation space data relay network. The inter-orbit optical links are essential segments for such a network in order to fulfill requirements of high resolution earth observation satellite applications and humaned space flight mission. In this paper, JAXA's R&D activities towards realizing advanced optical communication terminals are introduced. The target of the terminals is to establish the optical data relay link between LEO and GEO up to 2.5 Gbps of data-rate. The space data relay network with the terminals will provide seamless and high rate data downlink service for user spacecrafts in LEO.
