In fact, the entire launch work is far from over. The launch team still needs to perform remote measurement and control of the satellite. Calculate the orbit accuracy of the satellite, and then perform corrections.
The kinetic energy inertia of the satellite when it first enters orbit and the power carried by the satellite are used for precise positioning. The positioning here is not to fix it in a position, but to continue to accurately control the orbit of the satellite to ensure that it accurately enters the best orbit. And
We also need to control the orbiting speed of the satellite, either too fast or too slow.
At present, there is no rocket that can directly send satellites into an accurate predetermined orbit. It is a rough position. There may be a deviation of a few kilometers, which is acceptable, and then it needs to be adjusted through the power of the spacecraft itself.
Of course, some satellites that do not have high accuracy requirements do not require detailed adjustments.
Even if they are adjusted to orbit, these five satellites cannot be delivered to customers immediately because a series of subsequent tests are required. Only after all test work is completed and the satellites operate normally will they be officially handed over to customers.
"One arrow, five satellites! Haoyu Technology successfully launched five satellites into space using the Jianmu-1 A3 rocket at the Northwest R&D Center at 5:23 this morning."
In the morning, when everyone arrived at the office to start their work day, the news immediately appeared on the headlines of major news websites.
The first thing to be released was text information, followed by various breakthroughs and videos, which were forwarded by many media, public accounts, and bloggers.
For a time, this news quickly jumped onto the hot search list and became a topic that many people talked about.
"One arrow, five stars, awesome AC, how long has it taken? Haoyu Aerospace is developing too fast."
"It seems that Wu Hao really plans to invest in the aerospace industry and learn to be the domestic Musk."
"Wu Hao, can he compare with Musk? He has heavy rockets and his own manned spacecraft that can send people into space."
"That's right, that's right, what they are using is a real recyclable launch vehicle. Wu Hao and the others have made a copycat and have to use a parachute to land. Anyone can do it."
"What others have is theirs, and what we have is ours. In any case, this is another progress in our domestic private aerospace industry."
"The important thing about retractable rockets is that they can be recycled and reused. It doesn't matter which method is used."
"Which technology and method to use is still more important. Using a parachute will increase the overall weight of the rocket and reduce the transportation capacity, and the landing method is not as direct and efficient as the Falcon rocket. Of course, it also has its benefits, that is, it can reduce the load on the engine.
Work intensity and working time, save fuel, and extend service life under the same conditions.”
"With only one arrow and five satellites, Musk's Falcon rocket can send 60 satellites into space at once. Compared with others, Wu Hao is far behind."
"A bunch of illiterate people can't read the news. The difficulty of this launch is much more difficult than Musk's technology of 60 satellites happening together and then scattered into a star chain. Although this launch is only one arrow and five stars, it is
It uses the space shuttle, the upper-stage device, to send all five satellites to different orbits. This orbit-changing capability can rival the major aerospace powers."
"What's the use? It's not as good as others."
"It just means that you can't see us well."
"What are you doing above? You're just a licking dog who worships foreign countries. Even foreign farts taste good."
"Okay, ignore these clowns, let's talk about our business. Why doesn't Haoyu Technology use retractable rockets this time? Instead, it uses their Jianmu-1 A3 ultra-low-cost launch vehicle."
"It may be due to certain considerations. For example, some of the satellites launched this time have special orbital requirements, so it is difficult to recover the first stage part. This situation also happened with the Falcon rocket. When the US Army's advanced reconnaissance satellite was launched,
There is no recycling.
However, this is just a guess, and there may have been some problems after the last launch and recovery, which led to the failure to continue using it this time."
"Actually, this launch can be explained in terms of ballistic missiles compared to the Starlink launch of the Falcon rocket. The launch of the Falcon rocket is to send multiple warheads into space, and then fly along a fixed ballistic trajectory and slide down to attack the target.
The rocket launch of Haoyu Technology this time is like a ballistic missile with orbit-changing technology. The Jianmu-1 A3 rocket sends these warheads into the sky, and the upper stage changes orbit, and then selects the target to attack. In this way
Its concealment and suddenness will be greatly improved, and its anti-interception ability will also be several times higher than the survivability rate of fixed ballistic flying warheads."
"Master upstairs, it's much easier to understand when you put it this way. The Falcon rocket seems advanced and can send more satellites into the sky, but its orbit is fixed and single. As for the Jianmu-1 A3 rocket, although
The number of cargo carried is small, but it can carry out maneuverable orbit changes in space."
"Let me go, so these rockets also have military and strategic uses."
"Haha, you didn't forget Chang Yiyi. That thing is modified from a missile. The boundary between military and civilian use is actually very small. It's just as simple as changing the load and color. If you replace it with a warhead, it becomes a missile. If you replace it with a satellite,
, it is the launch vehicle.”
"Not necessarily. Today's missiles are all solid-fuel and can be launched at any time. Liquid missiles take too long to prepare and have long been eliminated."
"It has been eliminated a long time ago. Didn't you see the National Day military parade? The big guy behind it, Dong 5B, and the SS18 and SS19 from Goose Country are all liquid, aren't they?"
"So why does the state allow private companies like Haoyu Technology to own such dangerous things? Will there not be any problems?"
"If there is any problem, the supervision of this thing is very strict."
"Now the country not only allows it but also encourages it. In peacetime, this is to contribute to our country's aerospace industry and promote economic development. In wartime, this is the reserve force of the country's aerospace industry."
"Yes, if a war really breaks out, the first target that major countries must face is their satellites in space. As long as the satellites are destroyed, these countries will be blind, and many weapons and equipment will be paralyzed and cannot be used.
Therefore, at this time, it is necessary to urgently launch backup satellites into space. Whoever has more powerful launch power and can launch more satellites will naturally have an advantage.
Otherwise, why do you think Wu Hao and others can be so awesome? There must be state endorsement and support behind them."
"What's so strange about this? Who doesn't know that Haoyu Technology itself is an arms dealer?"
