Military Technology

In fact, the entire launch work is far from over, and the launch team still needs to carry out remote measurement and control of the satellite. The accuracy of the satellite's orbiting is measured and then corrected.

The kinetic energy and inertia of the satellite just entering 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 precisely control the orbit of the satellite to ensure that it accurately enters the best orbit. And it is necessary to control the orbiting speed of the satellite, too fast or too slow will not work.

At present, there are no rockets that can directly send satellites into an accurate predetermined orbit, and they are all in an approximate position. A deviation of a few kilometers may be acceptable, and then it needs to be adjusted by the power of the spacecraft itself.

Of course, some satellites that do not have high requirements for accuracy do not need to be fine-tuned.

Even if they are adjusted to orbit, these five satellites cannot be delivered to customers immediately, because a series of testing work will be required in the future. Only when all the testing work is completed and the satellite is operating normally will it be officially handed over to the customer.

"One Arrow, Five Stars! At 5:23 this morning, Haoyu Technology successfully launched five satellites into space with the Jianmu-1 A3 rocket in the Northwest R\u0026D Center.》

In the morning, when everyone arrived at the office to start their day's work, the news immediately appeared on the headlines of major news websites.

The text information was released first, followed by various breakthroughs and videos, which were reposted by many media, public accounts, and bloggers.

For a while, this piece of news quickly became the hot search list, and became a topic that many people talked about.

"Five stars with one arrow, awesome, how long has it been, Haoyu Aerospace is developing too fast."

"Haoyu Aerospace?"

"That's right, Haoyu Technology is a newly registered company."

"It seems that Wu Hao really intends to devote himself to the aerospace industry and learn to be a domestic Musk."

"Wu Hao, can he compare with Musk? He has heavy rockets and his own manned spaceship, which 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 counterfeit product, and they have to use a parachute to land. Anyone can do it."

"Others own what others have, and what we have is our own. In any case, this is another improvement in our domestic private aerospace industry."

"Retractable rockets, the important thing is that they can be recycled and reused. It doesn't matter which method is used."

"Which technology and method to use is quite important. Using a parachute will increase the overall weight of the rocket and reduce the 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. Reduce working intensity and working time, save fuel, and prolong service life under the same conditions."

"It's only five stars with one arrow. Musk's Falcon rocket can send 60 satellites into space at one time. Compared with him, Wu Hao is far behind."

"A group of illiterates, don't they know how to read the news? The difficulty of this launch is much more difficult than Musk's technology of sixty ones happening together and then throwing them into a star chain. Although this launch is only five stars with one arrow, it is It uses the space shuttle, which is the upper-level device, to send five satellites to different orbits, and this ability to change orbits can rival the major aerospace powers."

"What's the use? It's not as good as others."

"It means you can't see us well."

"What are you doing away from the one above? It's just a dog licking who worships foreigners. It's good for people to fart in foreign countries."

"Okay, forget about these clowns, let's talk about ours. Why didn't Haoyu Technology use retractable rockets this time, but use their Jianmu-1 A3 ultra-low-cost launch vehicle."

"Maybe because of some considerations,

For example, some of the satellites launched this time have special orbital requirements, so it is difficult to recover the first-level part. This situation has also occurred with the Falcon rocket. When the advanced reconnaissance satellite of the Mi Army was launched, it was not recovered.

However, this is just speculation, and there may be some problems after the last launch and recovery, which caused it to not be used this time, and it is unknown. "

"In fact, this launch is compared with the launch of the Falcon Rocket's Starlink with ballistic missiles. The launch of the Falcon Rocket is to send multiple warheads into space, and then fly and slide down along a fixed trajectory to attack the target.

And 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, and the upper stage changes the orbit, and then selects the target to attack. In this way, its concealment and suddenness will be greatly improved, and the anti-interception ability will be several times higher than the survival rate of fixed ballistic flying warheads. "

"Great talent upstairs, it's much easier to understand. The Falcon rocket seems to be advanced and can send more satellites into the sky, but the orbit is fixed and single. As for the Jianmu-1 A3 rocket, although The number of payloads is small, but it can maneuver and change orbits in space."

"I'll go, so these rockets have military and strategic uses."

"Hehe, you didn't forget Chang 11, right? That thing was modified from a ballistic missile. The military and civilian boundaries of this thing are actually very small. It's just as simple as changing the load and changing the color. If you change it to a warhead, it's a long-range ballistic missile. It becomes a satellite, it is a launch vehicle."

"Not necessarily. The current ballistic missiles are all solid fuel and can be launched at any time. Liquid missiles take too long to prepare and have been eliminated long ago."

"It has been eliminated a long time ago. You didn't see the National Day military parade. The big guy behind it, Dong 5B, and the SS-18 and SS-19 of Goose Country are all liquid."

"So why does the state allow private companies like Haoyu Technology to own such a dangerous thing? Will there be no problems?"

"If there is any problem, the supervision of this thing is very strict."

"Now the country not only allows but also encourages it. In normal times, this is to contribute to our country's aerospace industry and promote economic development. In wartime, this is the reserve force of the national aerospace industry."

"That's right, if a world war is really going to happen, the first target that the major powers must face is the satellites in space. As long as the satellites are destroyed, these countries will be blind, and many weapons and equipment will be paralyzed and unusable. .

So at this time, it is necessary to urgently launch a backup backup satellite into space. Whoever has the stronger launch force and who can launch more satellites will naturally have an advantage.

Otherwise, why do you think Wu Hao and the others can be so awesome? There must be a state endorsement behind them. "

"What's so strange about this, who doesn't know that Haoyu Technology itself is an arms dealer."
