What is the Musk Star Chain?

Musk's Star Chain is a project founded by elon musk, an American entrepreneur. It aims to build a network of thousands of satellites to provide high-speed and low-latency Internet services.

Star Link is the world's first constellation satellite and the largest constellation satellite that provides Internet services to users around the world by using satellites in low Earth orbit. It can support streaming media, online games and video calls.

The plan was first proposed by the United States (Elon Musk) on 20 15 and 1. The project plans to launch a space "star chain" consisting of about 12000 satellites into low-earth orbit from 20 19 to 2024, and the project has been put into use in some countries or regions since 2020.

"Star Chain" provides high-speed Internet services to users around the world through low-orbit communication satellites. In March 2022, the average download speed of 15 national satellite link exceeded 100Mbps, and on May 22 of the same year, the highest download speed of satellite Internet service in satellite link reached 30 1Mbps. As of March 2022, the Star Chain Project has provided Internet access services to more than 250,000 users worldwide.

Introduction to the technology and difficulties involved in the Musk Star Chain Project;

1. satellite communication technology: the traditional satellite communication system needs to build a large antenna station, which is expensive and cannot cover the whole world, so it needs large-scale distributed deployment of small satellites. Musk's solution is to develop self-designed Ku/Ka band Qualcomm satellite communication technology, which can realize high-speed data transmission and low delay.

2. Launch and operation and maintenance: As thousands of small satellites need to be deployed in orbit, the launch cost, operation and maintenance difficulty and failure rate are extremely high. In order to reduce costs and risks, Musk adopted the technology of quickly recycling reusable rockets, and used technologies such as robotics, artificial intelligence and blockchain to independently manage and maintain satellites.

3. Space-based network security: The establishment of a global Internet network needs to consider security issues. Musk envisions using technologies such as end-to-end encryption and virtual private network (VPN) to protect user data privacy and network security.
