Prospect of the successful launch of nebula-2 with one arrow and two stars

On May 12, Xingyun-2 was successfully launched with one arrow and two stars, which once again confirmed the rapid development of China's space industry. What is the significance and prospect of the successful launch of a binary star? Then let's reveal the constellation knowledge for you! Let's have a look!

One arrow and two stars successfully launched Nebula II. At 9: 00 on May 12, China successfully launched Nebula II 0102 at Jiuquan Satellite Launch Center. The satellite entered the scheduled orbit and the launch was a complete success. The 0102 launch of Xingyun II will carry out on-orbit verification of space-based Internet of Things communication technology, inter-satellite laser communication technology and low-cost commercial satellite platform technology, and initially carry out demonstration applications of the Internet of Things.

It is planned to establish a space-based Internet of Things constellation consisting of 80 satellites. China Aerospace Science and Technology Corporation's "Five Clouds and One Car" commercial aerospace project has been released for three years. Through technological innovation, business model innovation and management innovation, the commercial aerospace industry has been vigorously developed and a series of achievements have been made. Project Nebula is one of them. As the first space-based Internet of Things constellation in China to announce its independent investment, the "Nebula Project" plans to build a space-based Internet of Things constellation consisting of 80 low-orbit communication satellites around 2023 to solve the problem of "communication blind area" caused by the serious lack of cellular communication network coverage in the current terrestrial Internet of Things business. It is understood that "Xingyun II" 0102 adopted the inter-satellite laser link technology for the first time in low-orbit constellations in China, that is, the satellites in orbit can realize long-distance communication through laser communication technology, which can not rely on the transmission of ground stations, thus improving the real-time performance of communication services. In addition, the two satellites used the onboard digital multi-beam communication payload for the first time in China, and realized massive short data access through advanced communication protocols, becoming the earliest constellation system in China to realize the integration of operation, management and service. The successful launch of 0102 "Xingyun II" also means the successful completion of the phased construction task.

Space technology has changed life, and satellite applications have broad prospects. At present, the applications of communication satellites, remote sensing satellites and navigation satellites are everywhere, and space technology is playing a role in all walks of life, benefiting human life. The successfully launched "Xingyun II" satellite 0102 will provide communication technical support for its self-developed on-orbit series modules and product terminals, and can provide digital, networked, intelligent and real-time data communication and transmission services. According to reports, the dual-mode container supervision terminal independently developed by Xingyun can also provide timely, digital and intelligent supervision services such as location information, trajectory tracking, status monitoring and drug safety. Used for cold chain logistics supervision of sea or land containers, logistics vehicles and so on. For owners, owners, supervisors, etc. The position information and safety information status of cold chain items can be grasped in real time. The future market application prospect will be very broad.
