In fact, the entire launch work is far from over, and the launch team still needs to carry out remote tracking and control of the satellite. The accuracy of the satellite's orbit entry is calculated, and then it is corrected.

The kinetic inertia of the satellite just entered 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 exercise precise control of the satellite's orbit to ensure that it accurately enters the optimal orbit. And you also have to control the speed of the satellite, too fast and too slow.

At present, there is no rocket that can send a satellite directly into an accurate predetermined orbit, and it is all an approximate position. A deviation of a few kilometers is acceptable, and then it needs to be adjusted by the spacecraft's own power.

Of course, some satellites that do not require too much accuracy do not need to be fine-tuned.

Even if they are adjusted to orbit, these five satellites will not be delivered to customers immediately, because a series of tests will need to be carried out later. Only when all the test work is completed and the satellite is operating normally will it be officially handed over to the customer.

"Five Stars with One Stone! At 5:23 a.m. today, at the Northwest R&D Center, five satellites were successfully sent into space with the Jianmu-1 A3 rocket.

In the morning, when everyone arrived at the office to start their day, the news made headlines on major news websites.

The first thing to be released was the text information, followed by various breakthroughs and videos, and they were forwarded by many media and public accounts, and bloggers.

For a while, this news quickly became a hot search list and became a topic of conversation for many people.

"One stone and five stars, Niu B, how long has it been, Haoyu Aerospace has developed 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, he, can he compare with Musk, he has heavy rockets, and he also has his own manned spacecraft, which can send people into space."

"That's it, that's it, people are using a real recyclable launch vehicle, Wu Hao and them, they made a knockoff, and they have to land by parachute, whoever goes."

"What others have is their own, and what we have is our own. In any case, this is another progress in our domestic private aerospace industry. ”

"The important thing is that the retractable rocket can be recycled and reused, and it doesn't matter which way you use it."

"Which technology and method to use is more important, the use of parachutes will increase the overall weight of the rocket, reduce the capacity, and the landing method is not as direct and efficient as the Falcon rocket. Of course, it also has its advantages, that is, it can reduce the working intensity and working time of the engine, save fuel, and extend the service life under the same conditions. ”

"It's only five stars with one stone, but Musk's Falcon rocket can send sixty 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 of them happening together and then throwing them into a Starlink. Although this launch is only one rocket and five satellites, it is the use of the space ferry, that is, the upper stage device, to send five satellites to different orbits, and this orbit change ability can be compared with the major space powers. ”

"What's the use, it's not inferior to others."

"It means that we can't see us."

"What are you doing away from the one above, it's just a licking dog who admires foreign flattery, and it's fragrant for people to fart abroad."

"Alright, leave these clowns alone, let's talk about ours. This time, why didn't Haoyu Technology apply the retractable rocket, but use their Jianmu-1 A3 ultra-low-cost launch vehicle. ”

"It may be due to some considerations, such as the special orbit requirements of some of the satellites launched this time, so it is difficult to recover the first-stage part. This has also happened with the Falcon rocket, which was not recovered when the Mi Army's advanced reconnaissance satellite was launched.

However, this is only speculation, and it is also unknown what went wrong after the recovery of the last launch, which caused it not to continue to be used this time. ”

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

The rocket launch of Haoyu Technology is like a ballistic missile with orbit change technology. The Jianmu-1 A3 rocket sends these warheads into the sky, and the upper stage changes orbits, and then selects the target to attack. In this way, its concealment and suddenness will be greatly improved, and the anti-interception ability will also increase the survival rate of a fixed ballistic flying warhead by several times. ”

"It's much easier to understand than that. The Falcon rocket seems 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 carriers is small, it is capable of maneuvering and changing orbits in space. ”

"I'll go, so these rockets still have a military-strategic use."

"Hehe, you won't forget to grow 11. That thing was changed from a ballistic missile. The military and civilian boundaries between these things are actually very small, and it is nothing more than a simple matter of changing the load and changing the color. If you change it to a warhead, it is a long-range ballistic missile, and if you change it to a satellite, it is a launch vehicle. ”

"Not necessarily, today's ballistic missiles are solid-fuel and ready to be launched at any time. Liquid missiles took too long to prepare and were phased out long ago. ”

"It's been eliminated a long time ago, didn't you see the National Day parade, the big guy East 5B pulled behind, and the SS-18 and SS-19 in the country of Goose are all liquid."

"So why would the state allow a private enterprise like Haoyu Technology to own such a dangerous thing, won't there be any problems?"

"What problems can arise, this thing is very strictly regulated."

"Now the state not only allows but also encourages it, and in peacetime this is to contribute to our country's aerospace industry and promote economic development. And in wartime, this is the reserve force of the country's astronautics. ”

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

Therefore, at this time, it is necessary to urgently launch a backup satellite into space. Whoever has a stronger launch power and who can launch more satellites will naturally have more advantages.

Otherwise, why do you think Wu Hao and them can be so awesome, there must be national endorsement and support behind them. ”

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