[GeekWire website reported on July 5th] Amazon is requesting that the Federal Communications Commission (FCC) approve its name "Kuiper Project’s satellite broadband project, and the synergy with Amazon Web Services (AWS) is a major selling point.

GeekWire first reported in April “Project Kuiper.” Amazon disclosed its plan to deploy more than 3,200 satellites in low-Earth orbit to achieve global broadband coverage. The content of that disclosure was included in a document it submitted to the ITU. July 4 Kuiper Systems, a wholly-owned subsidiary of Amazon, reported some new materials to the FCC. These materials confirmed that the project will be networked by 3236 satellites distributed on 98 orbital surfaces, with an orbital height of 590 to 630 kilometers. Between.

The declaration materials stated, “Amazon’sIt is the most customer-centric company on the planet, and the "Kuiper System" is one of our ambitious projects to achieve this goal"; "The "Kuiper System" will provide services to hundreds of millions of consumers and consumers who lack services in the United States and around the world. Companies provide satellite broadband communications services.” Kuiper Systems cited relevant research results in its submissions. These studies show that 3.8 billion people worldwide lack reliable broadband services, while in the United States, 21.3 million people do not have access to fixed broadband. Service.

At the first public machine learning, automation, robotics and space exploration (re:MARS) conference hosted by Amazon last month, Amazon was the first Zos emphasized the reason for this high-risk project in a fireside conversation. He said that the purpose of the project is to spread broadband to every corner.

Kuiper Systems’ application materials stated that the satellite system will make full use of the expertise of Amazon, the Seattle technology giant in providing consumer services, and the foundation already built for “Amazon Web Services” facility. The application materials said: "Amazon currently sells products and services to hundreds of millions of customers through physical stores and online stores, entertainment content streaming, consumer electronics design and manufacturing, and leading cloud computing network services. Amazon also owns'Kuiper The system's global terrestrial network and computing infrastructure, including intercontinental fiber optic cables, data centers, computing/edge computing capabilities, and the tools, technologies and know-how needed to transmit data safely and efficiently."

The application materials stated that “Amazon will make full use of its resources and capabilities to developThe development, implementation and interconnection of the'Kuiper system' and terrestrial network". Such a statement seems to imply that "Kuiper" and the company's other businesses including online sales, cloud services and video streaming There is a connection.

In addition to Amazon, some other companies also have ambitious satellite broadband ambitions. For example, the space exploration company’s "Starlink" broadband constellation project has begun to move to the lowlands. Orbit deployment satellites. The company’s chief executive, Musk, said earlier this year that Starlink’s annual revenue is expected to reach 30 billion U.S. dollars or more. One network company, telecom satellite company and low-orbit satellite technology company also have low-orbit satellites. Plans to provide broadband services. This makes some experts wonder how many giant broadband constellations are needed in the world and how many satellites can be accommodated in the night sky.

In fact, the materials submitted to the FCC acknowledged that the satellites of Project Kuiper must get along well with other companies’ satellites in terms of broadcasting spectrum sharing and avoiding interference. "Kuiper" intends to use Ka-band frequencies, including part of the spectrum already in use by Iridium's next-generation communications satellite constellation. Kuiper Systems pointed out in the submission that the FCC has formulated a method for sharing spectrum by different companies, so the project is requesting the FCC to grant relevant exemptions to promote the adoption of systems and methods that will solve the interference problem. It also requested an exemption from compliance with the FCC's requirement to allow services to cover the entire United States and its territories, on the grounds that parts of Alaska are geographically too far north to receive satellite signals from the Kuiper constellation.

Kuiper SystemsAccording to the technical analysis, it can start providing satellite broadband services after putting 578 satellites into the correct orbit, thus ending the first phase of the five-phase deployment. Like Space Exploration's Starlink satellites, Kuiper Systems' satellites will first be sent to a lower orbit and will be upgraded after inspection.

The submitted materials did not specify the satellite design, but said that these satellites will use phased array antennas to form "direction-controllable and shape-plastic" beams. For safety reasons, these satellites will use "unpressurized, non-explosive propellants." In order to alleviate concerns about orbital debris, these satellites will be designed to de-orbit on their own in less than 10 years, even if they lose contact with the ground control department.

reportThe delivery materials did not mention when the satellite will be launched and which company will launch it. The Blue Origin company under Bezos's own name will logically take on this job, but this will become tricky because Amazon as a public company must avoid conflicts of interest.

The submitted materials confirm that Rajiv Bhatiyar, a satellite engineer who had led the space exploration company’s Starlink project, was reportedly fired last year. President and manager of Kuiper Systems.
