Earlier this year, news circulated online that China's satellite photo quality was among the worst in the world.
As soon as the news came out, netizens on major social media quickly began to discuss.
After many people see this topic, their first reaction is to affirm hype or false news. After all, China's current strength has been witnessed, and it has made rapid progress in high-tech, and scientific and technological innovation has even reached the top level in the world.
In the past, you said I can't do it, but now you say that our technology is poor, and Chinese netizens are not convinced.
Why is there a claim that China's satellite photos are the worst in the world?
The reason was that a freighter ran aground on Egypt's Suez Canal in the first half of this year, and satellites from many countries took and preserved photos.
Some lively people put the satellite photos of the United States, Turkey, France and China together for comparison, and the result was that at this time it was found that the stranded freighter taken by the old American satellite was extremely clear, and even how many goods were on board, what color the container was, and how it was distributed.
Only the photos taken by Chinese satellites account for only a small proportion of the freighters, as if they can only be placed in such a large focal length.
This has led many people to ridicule China's satellite photo shooting as the worst in the world, and there is no way to compare with the old beautiful high-definition photos.
Why is it that it's all 2023 now, and there are so many brainless sunspots spraying China?
We didn't do much response after this incident, after all, what these sunspots want is to disgrace China, and as for how you explain it, they will definitely not listen.
As Guo Degang said in crosstalk, the person who wronged you knows better than you how you were wronged.
Of course, China will not be as silent as before, after all, silence can only shoot back at reasonable people, and for unreasonable people, you still have to take out real knives and guns and hit them hard in the face.
Not long ago, after Japan announced that it would discharge nuclear sewage from the Fukushima nuclear power plant into the ocean, the mainland satellite was dispatched.
The satellite sent this time was "Jilin No. 1", and the results certainly lived up to expectations, and a large number of high-definition photos were soon taken, which not only allowed Chinese netizens to see how much nuclear-contaminated wastewater there was from Japan's nuclear power plants, but also completely shut up those who questioned that China's satellite technology was too poor to take pictures.
Photos taken by the "Jilin No. 1" can be seen that there are a large number of tanks storing sewage at the Fukushima nuclear power plant in Japan, densely arranged together.
It's hard to imagine the impact of this sewage being discharged into the ocean.
After seeing this set of photos, many netizens are also very curious, why were the pixels so unoptimistic when shooting the stranded freighter of the Suez Canal before, and now the Fukushima nuclear power plant is so clear?
This is because the two-shot guard is not an imaging mode at all.
The satellites that took the Suez Canal before used synthetic aperture radar images, and several countries that are more high-definition than our satellite photos used satellite photos of optical imaging, which are completely different satellite photos from two angles and principles, but they are compared together by people with intentions, which is really black for the sake of black China.
Some people may want to say that even if the tracks are different, then this photo is too mushy, right? It's much worse than the old beautiful photos.
Have you ever thought of the possibility that these four photos themselves are maliciously edited and stitched?
The satellite photo of the Suez Canal stranded cargo ship is the mainland's first commercial SAR satellite "Haise-1", the biggest feature is light and intelligent, the resolution is 1 meter, but the total weight is less than 185KG. Then according to common sense, the resolution of 1 meter is not low, but why is this photo still pasted like this?
Because this photo was enlarged and cropped by someone.
To explain it in the terminology of photography, Lao Mei used close-ups when shooting, and our "Haise No. 1" used a large panorama when shooting.
In layman's terms, A takes a picture of your pores with a camera, and B gives you a full-body photo. Then someone took a full-body photo taken by B and enlarged the skin to show the pore state taken, and then compared it with A's photo, saying that B camera is too bad and completely incomparable with A's.
Who is serious enough to make such a comparison? I almost carved something wrong with my face.
So how do we prove that China's satellite photo shooting technology is not bad at all?
The "Jilin No. 1" satellite that photographed Japan's Fukushima nuclear power plant is an optical remote sensing satellite, and the photos taken are naturally also optical imaging.
If you really want to compare which Chinese and foreign satellite photo shooting technology is stronger, you should still use our "Jilin No. 1" to compare with them.
However, after looking at the high-definition pictures sent back by "Jilin No. 1", why did someone make such a stupid mistake in the first place, and the answer to compare completely different satellite photos together is self-evident.
Because these people knew from the beginning that if the same horizontal line was used for comparison, it would definitely be better for China.
When these people lie in order to smear China, they are really not afraid of conscience.
So what exactly are the advantages of our "Jilin No. 1"?
As an optical remote sensing satellite, "Jilin-1" has been widely used in many fields in the mainland. Specific aspects of life, such as land surveying and mapping, traffic monitoring, smart city construction, etc., are inseparable from the help of optical remote sensing satellites such as "Jilin No. 1".
At present, the mainland has built such satellites into a system, which can monitor more than 800 target areas around the world every day at base stations.
What is the biggest feature of "Jilin No. 1"?
That's the pixel that was previously smeared.
The shooting pixels of "Jilin No. 1" are not to say the world's top, that is also the world's advanced level, the resolution can reach 0.5 meters, even the traffic zebra crossing on the ground and other details, can be fully reflected by satellite pictures.
Of course, our "Jilin No. 1" is not only outstanding in taking pictures, but also in terms of AI intelligent applications.
Through such satellites, monitors can obtain information on land surface changes in time, which greatly reduces the workload and is also the most important manifestation of the application of science and technology to life.
As an aside, on the afternoon of August 24, the Japanese discharged nuclear sewage into the ocean despite the opposition of various countries.
This is reminiscent of the saying that good words are difficult to persuade damned ghosts. What the Japanese do will surely be retribution to themselves first.
