China’s new-generation space-borne Internet-of-Things (IoT) project codenamed Xingyun-2 has successfully completed the communication link between the first two satellites in the network, marking a historical first in the country’s IoT space network, the Global Times learned from the developer on Thursday.
Technological testing for the laser communication payloads onboard the two satellites of the Xingyun-2 星云2 project achieved success, the project developer team with the LEOBIT Technology Co 莱奥比特科技公司 of the Wuhan-based Sanjiang Group, a subsidiary under the state-owned China Aerospace Science and Industry Corporation (CASIC).
The two satellites coded Xingyun-2 01 and 02 are the first two satellites of the network and they were launched on May 12 by the country’s Kuaizhou-1A commercial carrier rocket, which was developed by the Wuhan-based Sanjiang Group. And in-orbit tests have been in process ever since.
“Having successfully built communication link between the two satellites, all core technological tests for the spacecraft have been fully conducted,” the developer told the Global Times in an exclusive interview on Thursday.
Inter-satellite laser communication technology is to use laser beam to convey information in the forms of such as image, audio and signals, in space, in a high-speed fashion and with a strong interference-resistance capability.
By adopting such inter-satellite communication technology, the satellite constellation can reduce dependence on ground stations, saving the cost of building such ground facility, and at the same time, enabling the space-based network to cover larger areas to achieve global measuring and controlling capability.
