On November 21, according to foreign media reports, Amazon's satellite enterprise Kuiper systems is planning to build a satellite internet service called "project Kuiper". However, the company will not launch satellites using blue origin's rockets, and will not start internet services until 578 satellites are launched p> < p > < / P > < p > the Kuiper plan may be the latest example of the trend of building "giant Satellite Internet", and the star chain under SpaceX can be said to open the prelude to this trend. As early as early as 2019, when SpaceX was first launched, there were only about 5000 satellites orbiting the earth. At the time of writing, SpaceX had nearly 1800 satellites in orbit, accounting for about a quarter of the total number of satellites in orbit p> < p > as it becomes easier to enter space, these satellite networks can accommodate more satellites, they are closer to the ground and launch faster than ever before. However, as potential customers wait longer and longer for SpaceX to ship, many people have cancelled their orders. Maybe they can turn to the Kuiper plan p> < p > the maximum network speed is 400Mbps < / P > < p > Kuiper systems plans to send 3236 satellites into low earth orbit. Its goal is to provide people with insufficient traditional broadband services with high-speed, low delay and low-cost broadband Internet. According to its application to the FCC in 2019, the orbital altitude of these satellites will be between 590 and 630km p> < p > Dave limp, senior vice president of Amazon, said in a statement: "we have recently heard a lot of stories about people who can't finish their work or study because they don't have a reliable internet at home. There are still too many places where broadband access is unreliable or doesn't exist, and project Kuiper will help change this situation." < / P > < p > Kuiper systems will use the "low-cost customer terminal" to provide services to consumers. The satellite antenna has a diameter of 12 inches and a network speed of 400Mbps. Moreover, Amazon also said: "in the next iteration, performance and speed will continue to improve." < / P > < p > at present, it is not clear about the use fee of the satellite internet service of Kuiper systems, but Amazon has previously promised to invest more than $10 billion in this project. < / P > < p > in contrast, SpaceX star chain Internet charges $499 for the initial installation kit, followed by a service fee of $99 per month. Customers must pay a deposit of $99 to receive the kit The fee can be deducted from the final price of the installation package because Kuiper Systems describes its service as "affordable" , its price is expected to be competitive with the star chain Internet. < / P > < p > launch the prototype satellite at the end of 2022. < / P > < p > Kuiper systems has not announced the launch time of its satellite internet service. In November 2021, Amazon announced that it plans to launch two prototype satellites kuipersat-1 and kuipersat-2 for the project. By the fourth quarter of 2022, these two satellites will take the RS1 fire of ABL systems The arrow was launched from Cape Canaveral Air Force Base in Florida. < / P > < p > Amazon will use these satellites to test the prototype antenna in Texas five times a day with a maximum connection time of 4 minutes. After the mission is completed, Amazon plans to take these satellites out of orbit. In contrast, SpaceX launched two prototype satellites called Tintin A and Tintin B in 2018. SpaceX It was not until two years later that it began to provide testing services to customers. < / P > < p > it was recently reported that Amazon would not provide satellite Internet services until 578 satellites were put into orbit. In April this year, Amazon announced that it had obtained nine Atlas V launch opportunities for Kuiper systems, and these launch services would be provided by the joint launch Alliance (ULA) Available. < / P > < p > although Jeff Bezos He is the co-founder of Amazon and blue origin, but the former does not seem to use the blue origin rocket in the initial launch. Lin Pu once said in December 2020 that there is still great uncertainty in the satellite launch of Kuiper systems, and the team may recruit any available launch suppliers. < / P > < p > Kuiper plans to PK star chain < / P > < p > the operation altitude of the star chain satellite is slightly lower, which is the highest on earth The space is 550 kilometers. However, SpaceX has also applied for a license to launch 42000 satellites. In the test phase, the speed of the satellite chain can reach up to 200Mbps per second. In the long run, SpaceX's goal is to reach 10Gbps. < / P > < p > by the time Kuiper systems launched two test satellites, the satellite chain had provided two years of service. Amazon shelled SpaceX to try to reduce its satellite chain At orbital altitude, Elon Musk, CEO of SpaceX, publicly criticized Amazon's deployment plan. Amazon and other companies expressed concern that lower altitudes would interfere with other satellite networks. < / P > < p > in January 2021, musk wrote on Twitter: "Today, in order to put Amazon Satellite Internet system into operation in a few years at the earliest, it is not in the public interest to hinder the development of the satellite chain." < / P > < p > in response, Amazon issued a statement saying: "The fact is simple. We designed the Kuiper satellite system to avoid interfering with the satellite chain, and SpaceX now wants to change its system design. These changes not only increase the risk of space collision, but also increase radio interference to customers. Although SpaceX argued on twitter, its proposed changes will hinder the competition between satellite systems. Obviously, it will stifle the competition in the cradle Competition is more in the interests of SpaceX, but it is certainly not in the interests of the public. "< / P > < p > Bezos also clashed with musk over NASA's award of the SpaceX lunar lander contract, which will be used for the upcoming Artemis Return to the moon mission and send astronauts to the lunar surface. < / P > < p > now it seems that the Kuiper project is becoming another battlefield for the two billionaires.
