This can be said to be the layout of the last "large-scale" satellite launch in 2022. Jilin-1 will once again achieve the "six satellites with one arrow" situation.
This is also a layout for my country's commercial satellite market, and will also improve the layout of the entire "Jilin-1" satellite system.
2022 is coming to an end. From a time perspective, this may indeed be the last major satellite launch layout in 2022. There are not many satellite launches like "six satellites in one arrow" in our country.
It will also be the most perfect "final" satellite launch layout in 2022. So how strong is Jilin No. 1? Next, let’s first take a look at this “one arrow and six stars” thing, and then take a look at what the entire Jilin-1 can bring to our country.
"One arrow, six stars", Jilin-1 satellite will be deployed again
According to the news released at the end of December 2022, Changguang Satellite Technology Co., Ltd. held a departure ceremony for six satellites including the "Huashui-1" satellite, the "Wolfman" satellite, the "Haihe-1" satellite, the "Jilin-1" Gaofen 03D34 satellite, and the "Jilin-1" MF02A03~04 at the Changchun Aerospace Information Industrial Park.
The most typical one is the "Huashui-1" satellite ("Jilin-1" MF02A07 satellite), which is my country's first inland water remote sensing satellite and the first optical satellite of the "Huashui Constellation".
This satellite system is equivalent to a link in the layout of the "entire Jilin-1" system. Its particularity is the first lesson. After the layout is implemented, it will be able to obtain sub-meter high-resolution remote sensing images, with multi-mode imaging capabilities such as push broom, video, night light, and three-dimensional imaging.
is equivalent to the Jilin-1 satellite originally laid out, and has a certain improvement in earth monitoring capabilities.
Of course, this batch of satellites is also the most critical part of the entire satellite system. However, this time the expedition ceremony of "one arrow and six stars" was held.
It has not been specified how soon this batch of satellites will be launched directly. All I have to say is that the six satellites on this expedition will be launched from the Taiyuan Satellite Launch Center in China in the near future. After successful launch, they can provide a wealth of remote sensing data and product services for agriculture, forestry, meteorology, oceans, resources, environmental protection, urban construction, scientific experiments and other fields. This is the general situation.
Therefore, the launch layout of this satellite system may be the last major satellite layout in 2022. It is not clear whether it will be launched before the end of this year. It may also be the first "six satellites in one arrow" mission in 2023, giving a "good start".
Let’s talk about the issue of Jilin-1 satellite constellation.
How strong is Jilin No. 1?
Jilin-1 is an important optical remote sensing satellite constellation in my country, with more than 70 satellites deployed in space. Judging from the layout of the two stages, it has also entered the second stage.
The first phase, , realizes the on-orbit networking of 60 satellites, has the ability to revisit global hotspots within 30 minutes, and can observe more than 800 target areas around the world every day.
The second stage realizes the layout of a total of 138 satellites. Therefore, before the end of 2022, the layout of about 70 satellites has been achieved, which is considered to be half of the stage. After the completion of the second stage, it will have the ability to revisit any location in the world within 10 minutes.
can also provide a high-resolution, high-spatial-resolution remote sensing information acquisition platform, providing users with efficient and accurate remote sensing information services . However, the main application value of Jilin No. 1, or its strength, is in its monitoring capabilities, which is of great significance to my country's land and resources monitoring, land surveying , etc.
Moreover, the resolutions of its different satellites are completely different. For example: the optical A star has a full color resolution of 0.72 meters, the smart video star can achieve imaging of about 1 meter, etc. Therefore, on the issue of resolution, it is still relatively rare in the country.
However, although Jilin-1 constellation is a commercial satellite, there are also some special time periods that make the United States feel embarrassed. What is the situation?
That is, Jilin No. 1 can realize the monitoring of military aircraft. This is the hot topic that everyone is most concerned about. Indeed, Jilin-1 often takes geographical maps of foreign countries.
For example: Jilin No. 1 once took photos of the Philadelphia Navy Yard, the first naval shipyard in the United States, the United Arab Emirates Airport, Ferrari Theme Park , etc. Everyone thought they were very ordinary.
However, dynamic monitoring of the US military F22 fighter jets is not a problem, which surprises everyone. They did not expect that commercial satellite constellations are so powerful. Everyone should know that the F22 fighter jet is famous for its stealth performance and is said to be difficult to detect by the radar . However, the optical reconnaissance lens of the Jilin-1 satellite is not affected at all even if there are thick clouds and can still be detected. This is what everyone finds strange.
Indeed, this is also a characteristic of optical satellite constellations, which are not affected by radar systems. This is something that makes the United States ashamed, that it is so powerful.
Of course, as we said, this is just its additional effect, not the main one. It can only be said that in certain periods of time, it can achieve such strength, which is relatively good.
However, the optical satellite system also has shortcomings, that is, it is greatly affected by the external environment. You can also see from the picture that under the interference of clouds, its clarity will be affected. This is the difference, so it is a matter of pros and cons.
Summary
Overall, Jilin-1 is not the most perfect system, but it is still good in terms of reasonable use. After realizing the comprehensive layout of 138 satellites, the construction of the entire satellite constellation has been completely completed.
Over the years, many people should have seen that my country's aerospace technology is also on the rise among private enterprises . This also shows that the development of satellites is rising in different industries in our country, which is a good thing. It also shows the rise of China's aerospace technology, so come on.
