There is a global craze for building low-orbit satellite Internet of Things (with status and development trends of the satellite Internet industry)

Imagine that in the future, you will never lose contact with the world no matter when or where you are. This is the disruption brought about by satellite Internet.

Satellite Internet is an Internet based on satellite communications. It forms a large-scale network by launching a certain number of satellites to radiate around the world and build a large satellite system with real-time information processing. It is an Internet that can complete the provision of broadband Internet to ground and air terminals. A new network for access and other communication services, which has the characteristics of wide coverage, low latency, broadband, and low cost.

According to orbital altitude, communication satellites mainly include LEO (low earth orbit), MEO (medium earth orbit), GEO (geostationary orbit), SSO (sun synchronous orbit) and IGSO (inclined geosynchronous orbit). Among them, low-orbit satellites are suitable for the development of satellite Internet services due to their small transmission delay, low link loss, flexible launch, rich application scenarios, and low overall manufacturing cost.

It is precisely because of the "Internet of Everything" that satellite Internet can bring that this field has become one of the important directions for international competition.

Obviously, the United States has become the leader in this field, and companies such as SpaceX and OneWeb are actively promoting satellite Internet plans. In particular, SpaceX's Starlink program has entered an intensive construction period since 2020 and has launched more than 4,100 satellites.

In recent years, the Chinese government has also attached great importance to and supported the development of the satellite Internet industry. Many departments have successively issued a series of laws, regulations and incentive policies to assist the development of the industry. Among them, in April 2020, satellite Internet was included as a key direction of national "new infrastructure" policy support for the first time as an important information infrastructure, and the development of my country's low-orbit satellite Internet ushered in major development opportunities.

Our country has successfully launched a test satellite, but has not yet implemented the satellite network for the constellation project. According to the published satellite constellation plan, the total number of satellite Internet satellites is expected to exceed 16,000.

In the future, satellite Internet will develop from high-throughput communication satellites to high-frequency bands, build air, space and ground integrated network security guarantees and help the Internet of Everything achieve full coverage of new applications.

Tianfeng Securities believes that 2023 may be the first year of my country's low-orbit satellites. The "14th Five-Year Plan" stage is expected to complete the 0-1 leap, and all levels of the industrial chain are expected to achieve significant growth.
