| Abstract: | In order to meet the growing demand for big data and higher data rates, many space agencies including NASA, ESA, JAXA, are all engaged in developing laser communication technology. These space agencies are devoting themselves in proving the in-orbit performance of laser communication terminal of GEO-LEO, LEO-LEO, and LEO-Ground. This paper illustrates the development of laser communication technology demonstration experiments carried out by such space agencies, such as deep space laser communication and inter-satellite laser communication technology, with the analysis of the future trends in this field, and with an effort to give its value for domestic laser communication technology development. |
