摘要

Laser communication is an expected approach to realize a high data rate communication on small, micro and even cube satellites. Sony and Japan Aerospace Exploration Agency (JAXA) had experimentally verified fundamental functions of the small optical communication terminal with optical disk technology that is needed for miniaturization of light-weight and low power consumption laser communication terminals. To verify these functions from the optical disk technology in orbit as a laser communication system, Sony Computer Science Laboratories, Inc. (Sony CSL) and JAXA had jointly developed the small optical communication terminal called SOLISS from late 2017 that designed to be attached to the exposed facility of International Space Station (ISS) and it was successfully launched from Tanegashima in Japan on 25th September 2019. This experimentation aims to confirm 100 Mbps Ethernet-based laser communication establishment between low-Earth orbit and the ground and the availability of pointing control with the optical disk technology in-orbit. To achieve the goal, SOLISS continuously controls the accurate pointing with a coarse and fine pointing mechanism to keep the establishment of the optical link with a counterpart. In this experimentation, SOLISS successfully established the bidirectional Ethernet-based link with a PC connected to the optical ground station of National Institute of Information and Communications Technology (NICT) by its pointing mechanism. The result demonstrated the availability of the proposed pointing mechanism. This article discusses the pointing performance of SOLISS with the optical ground station.
