Musk disclosed the total parameters of the Starlink 2.0 satellite. Musk revealed that Space Exploration Technologies has built at least 65,438+0 available star chain V2.0 satellite prototypes and shipped them to the starship factory in South Texas. Musk disclosed the total parameters of the Starlink 2.0 satellite.

Musk revealed the total parameters of Starlink 2.0 satellite 1 elon musk, CEO of Space Exploration Technology Company, revealed the first technical details of the company's next-generation Starlink Gen2 satellite design, confirming that it will far exceed the current generation of satellites in almost all aspects. Musk said that Space Exploration Technologies has manufactured at least one fully functional prototype of the Starlink Gen2/V2.0 satellite and shipped it to the Starship factory in South Texas, where it is currently being stored.

More importantly, Musk did not conceal the data of these satellites at all, saying that each Starlink V2.0 satellite weighs about 1.25 tons (about 2,750 pounds) and is about 7 meters (about 23 feet) long, and its performance is one order of magnitude higher than that of all current satellites.

As early as August of 20021,I said that the biggest advantage of the space exploration technology company, Xinglian, is that it can be upgraded indefinitely, and the coverage of the whole satellite can be adjusted at any time, which is very flexible. However, the 250kg Mars Starlink and the deep space network Starlink can not meet the deployment of the entire constellation of Starlink, and will continue to upgrade in the future. It's 2.0 now, and it's estimated that the moon star league will be released at 6.0,660.

In addition, Space Exploration Technology revealed that the future starship can theoretically carry 1 10- 120 satellites, and everyone knows that the performance of the recycled starship is about 150 tons.

In this interview, Musk added that the capability of V2.0 satellite will be nearly an order of magnitude higher than that of Starlink 1. He refused to call this capability bandwidth or throughput, which is a traditional way to describe the overall performance of communication satellites, but the total bandwidth of Starlink V 1.0 satellites is 18Gbps.

Up to now, it is not clear whether Starlink V 1.5 (also a major upgrade) has increased the bandwidth, but even if V2.0 is compared with the earliest V 1.0 satellites, the bandwidth of each Starlink V2.0 satellite may reach 140- 160 Gbps.

In the final analysis, the details provided by Musk don't need specific figures to emphasize how powerful it is, but today almost all experts in the communication industry are guessing the available bandwidth of 2.0 satellites, which is conservatively estimated to be twice that of 1.0 satellites, and the total bandwidth of constellations will be even more amazing, and the bandwidth between constellations will increase exponentially.

For example, Falcon 9 will increase the instantaneous bandwidth of the constellation by about 1080 Gbps every time it launches 60 250kg Starlink V 1.0 satellites. If the Starlink V2.0 satellite of 120 1250 kg is launched by the starship, it will increase by about 19000 Gbps (19 TB per second).

Despite these great advantages, space exploration technology company is not proud at all. The FCC will soon approve its license application. Space exploration technology companies will need to launch half of the constellations within six years. Although the satellite is much larger, the launch and deployment of the starship will be very busy, but the return will also be high.

If the constellation consisting of 30,000 Starlink V2.0 satellites is evenly distributed around the earth, the total bandwidth on the land (excluding Antarctica) may reach 1.250 TB/s(TBPS) at any given moment.

In other words, even if all the satellites behind Space Exploration Technology are version 2.0, it can serve tens of millions or even hundreds of millions of users anywhere in the world. I have always said that Starlink is 6G or even 7G, and the whole solar system is interconnected. Now everything is going into space. Now even if the United States has any space fighter plans, I am not surprised, let alone communicate. This matter is too important.

By the way, now NASA is giving up its deep space network in low Earth orbit and handing it over to commercial companies. Space exploration technology company is one of them, and Starlink constellation will be of great use. In other words, Star Alliance can help Musk make money, but making money is by no means the main purpose of Star Alliance, and even 15% can't be achieved.

Musk revealed the general parameters of the Starlink 2.0 satellite on May 3 1, and rocket science blogger Tim Dodd released his latest video, showing his conversation with Elon Musk, founder and CEO of Space Exploration Technology Company.

In the process, Musk disclosed the technical details of the next generation satellite Gen2 (or V2.0) of Space Exploration Technology Company, and confirmed that the new satellite far surpassed the first generation satellite V 1.0 in almost all aspects.

Musk revealed that Space Exploration Technologies has built at least 65,438+0 available star chain V2.0 satellite prototypes and shipped them to the Starship Factory in South Texas, where they are currently stored.

More importantly, Musk also provided the design specifications for the next generation of satellites: each satellite chain V2.0 weighs about 1.25 tons (3 to 4 times more) and is about 7 meters long. Compared with the V 1.5 satellite which will be replaced eventually, the performance will be improved in an all-round way. In terms of useful data throughput, the new satellite is almost ten times that of the latter.

As early as August 20021year, it was speculated that space exploration technology company would try to optimize the design of its next-generation satellite chain, just like Falcon 9 rocket, in order to make full use of the launch performance of the starship.

In the latest satellite declaration document of satellite chain V2.0, Space Exploration Technology Company revealed that the satellite chain network optimized for starships will be improved in structural design, so that the rocket can launch satellites needed for the whole orbital plane at one time, that is, satellite rings evenly distributed around the earth.

Space Exploration Technology Company said that in the improved design, except for about 500 of the nearly 30,000 satellites (1.5%), all other satellites will be launched by spacecraft capable of carrying 1 10 or 120 satellites. In addition, the payload of the starship LEO estimated by Musk is 65,438+050 tons, which means that the weight of the optimized satellite V2 may reach 65,438+0,250 kilograms.

In this way, the weight of each star chain V2.0 satellite may be about three times that of the current V 1.5 satellite, but the throughput is five to 10 times that of V 1.5. Coupled with larger-scale mass production, this may explain the prediction in Musk's leaked memo. The memorandum implies that Star Chain V2.0 will be more sustainable and profitable than V 1.0 or V 1.5.

Musk has now made it clear that the weight of each V2.0 satellite is about 1.25 tons. The weights of satellites V 1.0 and V 1.5 are about 260 kg and 3 10 kg respectively, which means that the weight of V2.0 satellite will be about 4 times that of V 1.5, but less than 5 times that of V 1.0.

Musk also revealed that the performance of V2.0 satellite will be "one order of magnitude higher than that of V 1.0", but he refused to describe V2.0 according to the traditional method (bandwidth or throughput) to measure the performance of communication satellites, although the total bandwidth of V 1.0 satellite is considered as 18 Gbps.

So far, it is not clear whether the satellite chain V 1.5 has also increased more bandwidth. However, compared with the earliest V/KOOC-0/.0 satellite, each V2.0 satellite may increase the bandwidth of the space-based network consisting of 30,000 satellites by about/KOOC-0/40-/KOOC-0/60 Gbps. If true, this means that compared with V 1.0, satellite link V2.0 will pack about twice the available bandwidth into a given satellite quality unit.

In addition, the launch performance provided by the starship for low-earth orbit is 10 times that of Falcon 9 rocket. Theoretically, a single launch of a starship can be expanded. The total network capacity of the satellite chain is about 20 times that of Falcon 9 rocket. For example, Falcon 9 rocket launches 60 satellites weighing 260 kg at a time, which can increase the instantaneous bandwidth of satellite chain network by about 1080Gbps. Starship launches 120 star-chain V2.0 satellites weighing 1250 kg, which can increase the bandwidth by about 19000 Gbps.

Despite these great advantages, the goal of launching V2.0 satellite by Space Exploration Technology Company still faces many challenges. If the FCC approves the company's application, Space Exploration Technology will need to launch half of its satellites within six years, which is equivalent to launching 130 starships, with an average of about 22 times a year.

In contrast, since 20 10 began to fly, Falcon 9 rocket, which is ten times smaller than starship and less reusable, will not achieve the goal of 10 launching 22 times until 2020. In order to meet the launch rhythm required by V2.0 satellite, space exploration technology company must launch the largest rocket in history at a very high frequency and ensure that there is almost no failure in the launch process.

Although the challenge may be arduous, the potential return is also high. The network consisting of 30,000 V2.0 satellites can provide land (excluding Antarctica) with a total bandwidth of about 1250 Tbps at any given time. Even if the backhaul and routing need half the bandwidth, this is a huge progress compared with the total installed bandwidth of 600 Tbps of global Internet infrastructure in 2020.

At any point on the earth, the number of satellites that can be used at the same time is always the bottleneck restricting the satellite chain network, so the network can never compete with the terrestrial network with the same installed capacity. But what is certain is that if space exploration technology company can build and launch satellite chain V2.0, it will be able to serve tens of millions or even hundreds of millions of users anywhere on the earth.

Musk disclosed the total parameters of Starlink 2.0 satellite three days ago, in a video of space exploration technology company uploaded by foreign Up master EDA, Musk disclosed the technical data of Starlink V2.0 satellite with great interest.

It is reported that there are as many as 2,300 Starlink satellites currently in service in orbit, all of which were launched by Falcon 9 rocket. The latest model is v 1.5 version, with a length of less than 3 meters and a weight of less than 295kg.

According to Musk's sharing, version v2.0 of Starlink, that is, the second-generation star chain, has been produced, with a length of 7 meters, and the unit weight has actually increased to 1. 1~ 1.25 tons.

In terms of performance, Musk said that the communication capability of the second generation satellite link is almost 10 times higher than that of the first generation (v 1.0), and the beta version is almost an order of magnitude better.

At present, the highest speed measurement level of satellite links in some parts of the United States has reached 30 1Mbps, not to mention 10 times, even if it is five times higher, it will exceed gigabit. Only the current problem is that the uplink is seriously unequal and the delay is slightly higher.

Of course, whether the satellite v2.0 can be successfully deployed depends on when the Starship can be completed. It will not only undertake the task of manned landing on the moon and Mars in the future, but also be enough to deploy 400 second-generation satellite chains at one time. After all, using Falcon 9 is too inefficient.

According to the plan, Space Exploration Technology Company plans to deploy 2,200 v 1.5 satellite chains this year. Space exploration technology company Star Chain has more than 400,000 global users.
