Two satellites for China's space-based Internet-of-Things (IoT) project have completed phase-1 tests in orbit, sources with the China Aerospace Science and Industry Corporation said.

The satellites, Xingyun-2 01 and 02, were launched by a Kuaizhou-1A carrier rocket on May 12 from the Jiuquan Satellite Launch Center.

Engineers tested the satellite platforms, payloads, and key technologies such as inter-satellite links. The results were in line with expectations, the corporation said.

Additional in-orbit tests will be continued for the completion of the Xingyun project, China's first self-developed, space-based IoT constellation.

The project is anticipated to solve problems detected in the IoT businesses' communication blind-zone, as a result of deficient coverage of cellular wireless communication networks.

By around 2023, the Xingyun project will have completed construction of the space-based IoT constellation with 80 low-orbit communication satellites.

The Xingyun-2 01 and 02 satellites employ the technology of inter-satellite laser links, which enables the in-orbit satellites to communicate over long distances and hence upgrade the real-time performance of communication services.

Scientists propose data encoding method for the 6G standard
Saint Petersburg, Russia (SPX) Jun 15, 2020
Researchers around the world are working on ways to transfer data in the terahertz (THz) range, which would make it possible to send and receive information much faster than what is allowed by today's technology. But the issue they're facing is that it is much more difficult to encode data in the THz range than in the GHz range, which is currently used by 5G tech. A group of scientists from ITMO University have demonstrated the possibility of modifying terahertz pulses in order to use them for dat ... read more
