The appearance of advanced satellites with high power and the cost reduction of earth stations enabled universities to conduct experiments using actual satellites. Taking account of this situation, the University^<, >s Joint Study Group for Digital Satellite Communications (UnSAT JSG) has been established, in which more than forty universities in Japan, two universities each in Korea and China join and about thirty universities are actually carrying out experiments using their own earth stations via Ku-band satellite. The experiments cover a variety of study fields such as radio propagation characteristics, communications scheme, network structure between universities, transmission and security of video, image and computer data. Considering that satellites have an inherent potential to provide borderless communications, it is expected by the international cooperation that the experiments via satellite will widely spread over the Asia-Pacific region in the near future.

高功率先进卫星的出现和地面站成本的降低使大学能够利用实际卫星进行实验。考虑到这种情况，日本40多所大学、韩国和中国各2所大学和30多所大学组成了“数字卫星通信联合研究组（UnSAT JSG）”，正在通过ku波段卫星利用各自的地面站进行实验。实验内容涵盖无线电传播特性、通信方案、高校间网络结构、视频、图像和计算机数据的传输与安全等多个研究领域。考虑到卫星具有提供无边界通信的内在潜力，国际合作预计，通过卫星进行的实验将在不久的将来在亚太地区广泛推广。
