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 and inertia of the satellite when it first enters orbit and the power carried by the satellite itself are used for precise positioning. The positioning here is not to fix it in one position, but to continue to accurately control the orbit of the satellite to ensure that it accurately enters the optimal orbit. And we also need to control the orbiting speed of the satellite. It doesn't work either too fast or too slow.
At present, there are no rockets that can directly send satellites into accurate predetermined orbits, which are all approximate positions. There may be a deviation of a few kilometers, which is acceptable, and then it needs to be adjusted through the spacecraft's own power.
Of course, some satellites that do not have high accuracy requirements do not require detailed adjustments.
Even after being adjusted to orbit, these five satellites cannot be delivered to customers immediately because a series of subsequent tests are required. Only when all testing work is completed and the satellite operates normally will it be officially handed over to the customer.
"One Arrow, Five Stars!" 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 workday, the news immediately appeared on the headlines of major news websites.
The first thing 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 appeared on the hot search list and became a topic that many people talked about.
"One arrow and five stars, awesome! How long has it been? Haoyu Aerospace is developing too fast."
"Haoyu Aerospace?"
"That's right, Haoyu Technology's newly registered company."
"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 knockoff 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 one time. Compared with him, Wu Hao is far behind."
"A bunch of illiterate people, don't know how to 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 with the one 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 the retractable rocket 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 speculation, and it is also unknown that something went wrong after the last launch and recovery, which led to it not being used again 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.
This time Haoyu Technology’s rocket launch is like a ballistic missile with orbit-changing technology. The Jianmu-1 A3 rocket sends these warheads into the sky, changes their orbit from the upper stage, 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, this makes it much simpler to understand. 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 vehicles 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 to grow 11, did you? That thing is a ballistic 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 change the warhead, it will be a long-range ballistic missile. If it becomes a satellite, it is a launch vehicle."
"Not necessarily. Today's ballistic 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 at the back, East 5B, and the SS-18 and SS-19 from Goose Country are all liquid."
"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."
"That's right, if a world 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. .
So at this time, it is necessary to urgently launch backup satellites into space. Whoever has stronger launch power and can launch more satellites will naturally have an advantage.
Otherwise, do you think that why 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?"
