Quantum Science Satellite is one of the first five space science missions, slated for launch in the framework of Chinese Academy of Sciences (CAS) Strategic Priority Research Program on space science. The project aims to establish a space platform with long-distance satellite and ground quantum channel, and carry out a series of tests about fundamental quantum principles and protocols in space-based large scale. The satellite will be launched at Jiuquan and on orbit for 2 years. The orbit will be circular and Sun-synchronous with an altitude of 600km. It crosses the descending node at 00:00LT. The satellite is under early prototype development currently. 相似文献
