A breaking news on October 4 caught everyone off guard. Musk, who has been spared no effort to support Ukraine, launched a vote on his Twitter. The key is that the rule setting of this vote seems to be completely one-sided to Russia. The general content is as follows:- Voting is

On October 10, 2022, an Twitter account with ID @Terror_Alarm posted a tweet saying that Musk's starlink signal suddenly weakened in the hot spots that Ukraine needs most. At present, Ukraine suspected that the Ukrainian people's excessive remarks angered Musk.

I believe everyone is very curious about this unexpected trend. How did Musk, who has always supported Ukraine, annoyed the Ukrainian people? And how did starlink become the most urgent need in Ukraine? Let’s briefly summarize the following.

pro-Russian remarks fermented: Musk successfully annoyed the Ukrainian people

A breaking news on October 4 caught everyone off guard. Musk, who has been spared to support Ukraine, launched a vote on his Twitter. The key is that the rule setting of this vote seems to be completely one-sided to Russia. The general content is as follows:

  1. - Re-vote under the supervision of United Nations . If this is the will of the people, the Russians will leave;
  2. - Crimea is part of Russia, and has been like this since 1783 (until Khrushchev makes a mistake);
  3. - Ensure the supply of water to Crimea;
  4. -
  5. - Ukraine remains neutral; there are only these four prerequisites for

, and the voting options are YES or NO. Guess what the voting result is? In the end, there were a total of 2748,378 valid votes, of which 40.9% agreed and 59.1% opposed. It seems that everyone still opposes Russia's attitude towards Crimea.

Although this voting result is more beneficial to Ukraine, it still annoyed many Ukrainians , because Musk's setting is almost tailor-made for Russia. If you vote again in Crimea, it is probably still to maintain the current results! But this matter is not over. Because of this voting operation, the Ukrainians have already formed a foul with Musk, so they all went to his Twitter to scold, which was simply unsightly!

However, Musk was not satisfied with this operation. He also realized that the rule setting may be more pro-Russian, so he set up another vote to remove all the rules, and the content was extremely simplified:

let the people living in Donbas and Crimea decide whether to stay in Ukraine or Russia;

this time it seems fair, but the result made everyone a little stunned, because 59.3% of the people agreed to decide on Donbas and Crimea themselves. If this vote is used, the Ukrainian government's high-pressure rule over the eastern Ukrainian region is estimated to be higher than this Twitter vote. This is even more furious. Originally, it only annoyed the Ukrainians, but now the Ukrainians are just angry.

Ukrainian people ran to Musk's Twitter to curse (or also many "international friends" who support Ukraine). Many remarks are not even suitable for posting for everyone to observe. The author will choose a few messages that can be read:

these are relatively rational messages, and the author will not post them. Although there are people who agree with Musk's approach, they have basically been overwhelmed by the messages scolding him. Of course, Ukrainians are not satisfied with this. For example, there is a comment saying that Putin likes Musk's proposal very much, so a PS expert Paired Musk into a Russian soldier:

? Musk's smiley face and this military uniform are indeed very suitable for Musk's temperament. In these messages, there are also people pointing the finger at Musk's Starlink. Since the Russian-Ukrainian conflict, Musk's Starlink has made a lot of efforts for Ukraine, but because of this incident, the Ukrainian people have spoken rudely:

This message stuffs the Starlink into Musk's butt. This ID is currently no longer found on Twitter. I don't know if it triggered Twitter's ban mechanism or because Musk is about to acquire Twitter, but it is gone anyway.

In the end, the driver also ended up and he also made a vote. Everyone likes Musk who supports Ukraine or Musk who supports Russia. As a result, there are 25,204 valid votes, and 95.1% of the support is from Ukraine.

So this time, the Starlink signal signal was seriously weakened on the battlefield of the Russian-Ukrainian conflict. Everyone doubted whether Musk did it on purpose, or maybe this was a way for Musk to retaliate against Ukraine's unscrupulous remarks?

Starlink signal weakened: Is it Musk's revenge or Russian equipment interference?

Musk's Starlink provides battlefield communication for the Ukrainian military, and the signal comes from low-Earth orbit. This method of Internet access was extremely expensive before, but large-scale low-Earth orbit communication constellations have been established, and Starlink is one of them. What is the reason for the weakening of Starlink signal? This requires understanding the basic principles of Starlink before continuing to discuss.

Near Earth Orbit Internet Communication Constellation

The principle is quite simple, that is, to arrange satellite in low Earth orbit, establish a communication channel between the ground base station and the client, which is equivalent to an bridge , quickly connecting the client to the global Internet. Another way is to first connect the ground station to the satellite, and then land on the nearest ground base station to access the global Internet through the inter-satellite link between satellites.

This communication method has obvious advantages. It can access the Internet from any location in the world, whether it is mountains or oceans, as long as there is an over-top satellite. The disadvantage is that it requires a set of ground station , but it is not large in size, that is, the household satellite pot is slightly larger, which is quite convenient to use.

But the most fatal disadvantage lies in the construction of communication satellite constellations. If you want to ensure that any location in the world can be accessed smoothly at any time, if it is a high orbit, such as an orbit more than 1,000 kilometers, then at a certain coverage rate, at least 600~700 satellites are required. The power requirements for satellite transmission and ground client are relatively high and the delay is relatively large. If the orbit is reduced, the transmission power requirements will be reduced and the delay will be reduced, but the number of satellites will increase exponentially. So far, there are about the following low-Earth orbit communication constellations in the world:

  • 1, SpaceX starlinks: 42,000, with a height of 550 kilometers and 350 kilometers;
  • 2, China GW Zodiac signs: 12,000 satellites, with a height of more than 500, 600, and 1,100 kilometers;
  • 3, OneWeb constellation in the UK: 648 satellites, with a height of 1,200 kilometers;
  • 4, Amazon Kuiper system;
  • 5, others include Viasat, O3b, Iridium systems, etc.;

is mainly these Internet constellation systems, among which Starlink has completed more than 3,000 satellites, and OneWeb has completed 428 satellites. At present, the world can access the Internet in some areas in some time periods, so both have been officially put into commercial use. Among them, Starlink has the highest commercial use and there are multiple speeds to choose.

After the Russian-Ukrainian conflict broke out at the end of February 2022, Ukrainian President Zelensky tweeted that Musk asked Musk to open Starlink for use for the Ukrainian army, which was recognized by Musk. After that, a large number of Starlink clients were sent to the Ukrainian capital Kiev , and were then distributed to the grassroots level for use.

To be precise, Ukraine is not the first military use attempt of Starlink. As early as the beginning of Starlink construction, the US military actively explored the military use of Starlink. The US military has long included Starlink in a backup of the data link. In some cases, the US military's data link can maintain communication through Starlink.

Ukraine's personal client model is the lowest-level application of Starlink military use, but even so, it is very widespread. For example, battlefield reconnaissance, the Starlink beam is very narrow and communication is not easily exposed. It can be used as long as the satellite is overtopped. In addition, Starlink can load a large amount of data, and can even maintain live broadcast of high data streams. Therefore, it is an absolute bonus option for the Ukrainian military's forward-looking data links incomplete or large-scale destruction.

The Russian military was also so angry that it was itchy for Starlink to play its role in Ukraine. However, because Starlink is an asset of the United States, it could only endure it without expanding the scale of the war. If Ukraine had its own facilities, it would have been destroyed long ago.

Musk reduces signal transmission power?

The above briefly illustrates the principle of Starlink. Theoretically, it is possible to reduce the power transmission signal in a certain area, or even have no signal, because Starlink has a fixed operating orbit, and the projection position of the lower star point is easy to determine. Therefore, it is possible to reduce or even close the Starlink satellite signal in a certain place. Of course, it can also be turned off certain access clients, which is also easy to do.

However, from the perspective of the national will of the United States, this matter was definitely not done by Musk. For example, shortly after the Russian-Ukrainian conflict, Zelensky asked Musk for help and quickly received a reply: Yes, and the client was sent to Ukraine, but in fact this was not something Musk could decide. The Starlink service for Ukraine needs to be approved by the US Congress. It is not that Musk agreed if he said he agreed. The interaction between the two on Twitter is just acting.

So Musk cannot cut off the service of Starlink in Ukraine at will. This is the national will of the United States. If it is Musk, it must be authorized by Congress, that is, the United States began to weaken its support for Ukraine. But at the moment, there seems to be no reason. Moreover, from the perspective of the United States setting up a center in Germany to supervise European military aid to Ukraine, supporting Ukraine will only strengthen and not weaken.

Interference with Starlink: Does weaken the signal-to-noise ratio of Starlink signal?

Starlink client uses phased array antenna , that is, the direction of beam can be changed without adjusting the orientation of satellite antenna . The antenna has no moving parts, so it can be roughly aligned with the starlink satellite transit area, which makes the antenna very convenient to use. From this perspective, we can also understand that the angle of this beam is relatively narrow and it is difficult to interfere with the star link. There are several ways to interfere with

. The Starlink satellite that sends the signal is difficult to destroy because it can operate in low-Earth orbit, and only transmit signals to reduce their signal-to-noise ratio, or use noise to drown the normal communication signal . Another method is to interfere with the uplink, because the Starlink client also needs to uplink data in addition to receiving signals, otherwise it will not be bidirectional communication.

But the more troublesome thing is that the previous article said that the beam of the starlink is very narrow, and this communication method is still relatively difficult for interference. Moreover, maintaining high-power interference in a certain place for a long time can easily lead to attacks from anti-radiation missile . From this point of view, in addition to the possible interference in hot spots, it seems unlikely to maintain large-scale interference for a long time.

So far, there is no answer to the reduction in the starlink signal strength in some parts of Ukraine. After all, this involves too many factors, or reasons for the US government, or Starlink satellite factors, or reasons for Russian interference, etc.

Musk has recently remarks about Taiwan, and it is more in line with our position. I believe many people have started to cheer. Although the flower growers also highly recognize Musk's recent statement about Taiwan, my country, one thing must be recognized. Musk is a businessman, and his position can be changed for the sake of business. As long as you remember this, I believe that it is not difficult for you to understand Musk's position.
