Chapter 617: Live Broadcast Releases Satellites, Human Satellite Technology Enters a New Level!
The failure reported by GISAT-5A caused chaos in the satellite center of a certain three.
GISAT-5A, it's too important.
This large-scale optical reconnaissance satellite was manufactured by a certain space research organization, and it used expensive imported high-end optical equipment and electronic system equipment, with a total cost of nearly $700 million.
In the same direction, it is already quite expensive.
The cost of the world's high-end large-scale optical reconnaissance satellites is only between $200 million and $400 million.
GISAT-5A, which costs so much money and is independently developed by a certain three space research organizations, also has a certain representative significance.
At the same time, GISAT-5A is also the most high-end reconnaissance satellite of the three militaries, and it has strategic problems that are directly related to the military's reconnaissance capabilities.
GISAT-5A has problems, but it is not what they want to see, and it will not only cost a lot of money to build another satellite with the same performance, but also need to wait a long time.
In the panic of the personnel of the satellite center, a leader asked angrily, "What happened to the satellite?" ”
Personnel at the satellite center reported that "there were two faults, one was a sudden orbital shift." ”
"We didn't turn on the built-in power system, we didn't make track adjustments, but the GISAT-5A had a sudden orbit shift, and the declination angle was still very large......"
"Satellite-reported failures are the big problem. The orbit offset can be readjusted back, but the solar panels are damaged, which can cause the satellite to lose control! ”
"This kind of failure is very rare, and it is known only twice in history. One is Ameriken's reconnaissance-reconnaissance satellite, and the other is the geostationary orbit satellite of the former Goose Union. ”
"The failure of the American satellite is determined to be caused by a failure of the power system."
"Was the satellite of the former Goose Union a quality problem, or was it ...... fifty years ago"
The personnel of the satellite center explained.
Solar panel damage is a very rare failure, because the solar panel technology content is very low, and the technology is all reflected in the material performance, and the possibility of failure is very small.
Conventional satellite faults are generally power supply failures, transmission system failures, orbit control failures and load system failures, which are all linked to electronic systems and can be self-checked and repaired.
Solar panel damage, most likely physical damage, is not possible for self-inspection and repair.
"Is it a quality problem?" Someone said speculatively.
The high-end weapons and equipment they independently developed often fail due to poor quality.
Even in the field of aerospace with high technical precision, similar problems occasionally occur, but relatively few in other fields.
Someone immediately denied, "It can't be a quality problem." ”
"This is not a separate failure report, the satellite also had an orbital shift, both at the same time."
"The solar panels just malfunction, not fall off, and will not affect the orbit of the satellite."
"We don't know the specific fault situation yet, so we can only wait for the satellite to send back photos......"
Others can only continue to wait.
The GISAT-5A is equipped with high-precision optics, and after adjusting the camera lens, it is possible to capture damaged solar panels and send back high-resolution photos.
However, GISAT-5A is not a communication satellite, and the radar communication system is relatively poor, and all that is transmitted back is digital information, and it takes at least an hour to wait for at least an hour to receive the information and convert it into photos.
Soon.
Ameriken also knew the news, and they immediately realized that the situation was not ordinary.
"It's no coincidence!"
"The failure of the GISAT-5A at a distance of about 80 km from the light source engine."
"Orbital offset, as well as damage to the solar panels, both occur at the same time, and the chances that our analysis considers it to be a coincidence are very small."
"There is a more than 90% probability that it is related to some kind of space weapon technology of the flower planter, or to the light-pressure engine itself."
This is the conclusion of a quick analysis.
In fact, there is no need to analyze it carefully, and if you think about it, you will know that the situation is not ordinary.
The probability of a satellite failure is very low, how can it catch up with the edge of the space control area, when it is closest to the light pressure engine, and suddenly there is a failure?
"The question is, how do they do it?"
"We did not detect the energy anomaly, the light pressure engine did not fire laser weapons, and the satellite directly failed......
"It still depends on the damage to the solar panels, and we can analyze it according to the specific situation."
"How long will it take for a certain three to be able to resolve the photo?"
"About an hour."
A member of the satellite center suddenly reported, "We found that the orbit of GISAT-5A is very similar to the last crashed TSA-395." ”
"Both satellites had a sudden orbital shift, as if they had suddenly been subjected to some special force."
This information led to Amriken's determination that the failure of GISAT-5A was directly related to the planter's mysterious space weapon technology or light-pressure engine.
Tests of the light-pressure engine continue.
After Zhao Dahe operated the engine to approach the GISAT-5A and carried out the mission of gravitational shield jamming satellites, he couldn't help but exhale lightly and said to the other two, "We actually hit a satellite." ”
"It's not a direct blow, but it's a big impact."
"If you can say it in the future, this matter can be blown for a lifetime......"
"yes!"
The other two were also very emotional, they never thought that one day they would be able to use space weapons to attack a satellite with an altitude of more than 500 kilometers.
They discussed it together and then continued to focus on their work.
The next task is to release the V191 satellite.
Satellite release is very important, and cooperation with the military is one thing, and the spacecraft company wants to use the opportunity to announce to the world that they have the ability to launch and release very large satellites.
The process of satellite release will also be broadcast live to the world.
The live broadcast of the space test of the light-pressure engine continues, and the engine has completed take-off acceleration and ascended to an altitude of nearly 600 kilometers.
Speaking of which, it seems to take a long time, but in fact, the total time is only a little more than an hour, including the pre-preparation and take-off time, and it is only half an hour from the time of liftoff.
The vast majority of people who watched the live broadcast were unaware of the problems with GISAT-5A, and even said that they did not even know that such a satellite existed.
They are just watching the test of the light-pressure engine, waiting for the upcoming release of the satellite.
After the interference of the GISAT-5A, the light-pressure engine did not return to its original orbit, but continued to accelerate after slightly adjusting its direction.
When the established speed and direction are reached, the work on the release of the satellite officially begins.
The live broadcast screen is connected.
At this time, the picture has become a space perspective, and the live broadcast is shot by several high-definition cameras that come with the optical pressure engine.
The perspective of several high-definition cameras can be continuously changed, and the live broadcast with a clear perspective can be carried out, which also makes the audience who watches the live broadcast feel very surprised.
Countries have launched many satellites into space, but rarely see the release of satellites in space.
Generally, after a satellite is launched into space by a rocket, the satellite release, orbit control and operation process can only be understood through animation simulation.
It's not that countries don't want to show high-end space technology, or because the release process of satellites is not attractive, but because ordinary satellites don't have the ability to transmit data quickly.
To put it simply, the data transfer speed is seriously insufficient.
Even if the built-in camera has good performance, the data cannot be transmitted in time, and it will naturally be impossible to watch live.
Gas-only engines are different.
The engine is equipped with first-order radar equipment, as well as other high-end information processing and transmission equipment, and the data transmission speed is very fast, which can transmit data with high precision and no delay, and can also carry out high-definition live broadcast.
Just by watching the live process, professionals can analyze a lot of things.
"They're using digital signal transmission."
"The picture is very clear and stable, and there is no lag, which means that the transmission speed is very fast."
"It's very unusual......"
There are two ways of general data transmission, one is digital signal transmission and the other is analog signal transmission.
Ordinary videos are transmitted by digital signals, which can have a high resolution, and the picture will be very clear, but the problem is that digital signal transmission is easily interfered with by the atmosphere and other radar signals, and the transmission process may be somewhat unstable.
It is difficult to achieve continuous efficiency and stability in digital signal transmission on the ground in space.
Another way is analog signal transmission, analog signal transmission will also be unstable, but it can provide a continuous picture, but when the signal is unstable, the resolution will be greatly reduced, and there may even be a blurred screen.
The fact that the light-pressure engine can achieve such stable and efficient data transmission also represents an extremely high-end data transmission technology.
Ameriken made a judgment, "It is likely to be some kind of high-end information transmission technology, which may be related to first-order electromagnetic waves." ”
"This is also proof that they have mastered first-order radar technology!"
In the live footage, the release of the satellite began.
From the perspective of the one-sided lens, the light-pressure engine surrounds the capsule, and a small part of the hatch opens, and the large satellite slowly rises from the capsule.
When it rises to a certain height, it can be clearly seen that the connection and control of the large satellite is a V-shaped boom, which is somewhat similar to the boom of an excavator.
The satellite was hoisted away from the capsule, about forty meters away, and the V-shaped boom was stretched to the limit.
The fixtures at the boom and satellite connections open.
At this time, the satellite can be seen to tremble, a power tail appears in the rear, and the satellite begins to accelerate away from the boom.
The next thing you see is the satellite moving away from the light-pressure engine.
It quickly disappeared from view.
The host of the first media said, "Next, the satellite will rely on its own power to go to the predetermined orbit ......"
The release of the satellite has come to an end.
Whether the follow-up satellite can reach the established orbit and whether it can operate normally is the problem of the satellite itself, and has nothing to do with the launch of the light-pressure engine to release the satellite.
There are also many people in the Internet public opinion who began to celebrate, "The satellite release has been successful!" ”
"Congratulations on the success of the release of ultra-large satellites by the light-pressure engine, and the phased success of the engine test......"
"Mankind's satellite technology can enter a new chapter!"
Ordinary people just shouted as if they were in the fun, and companies with satellite needs began to consider making super-large satellites.
The larger the satellite, the more performance it can achieve.
If we can build ultra-large satellites of tens or hundreds of tons, the performance of satellites will definitely be greatly improved.
The only problem is that it is not known whether the light-pressure engine will be able to help launch satellites in geosynchronous orbit, which are more commonly used in the commercial sector.
For example, in the field of communications.
Satellites used in the field of communication need to be in the same position for a long time to ensure the stability of communication.
The altitude of geosynchronous orbit satellites exceeds 35,000 kilometers, and the launch of geosynchronous orbit satellites generally requires a climb of more than 30,000 kilometers.
After that, the satellite will be able to continue to climb until it is adjusted to a suitable altitude and position.
At present, the altitude of the light-pressure engine test is only about 1,000 kilometers, and the distance of more than 30,000 kilometers is still a bit far.
In this regard, it is also necessary to communicate with the spacecraft company to see if relevant cooperation can be carried out in the future.
After releasing the satellite, the light-pressure engine continued to climb upward, adjusting its direction to face the Earth's surface, and then continued to glide and ascend at the existing speed.
Ground control room.
Zhu Qiqiang reported on the engine situation, "At the current speed, the engine is expected to rise to an altitude of 1,230 kilometers, more than 100 kilometers higher than planned." ”
This was mainly due to the sudden execution of the mission in the middle of the mission, which affected the original plan.
Zhu Qiqiang asked, "Do you want to slow down?" ”
Wang Hao thought for a while, shook his head and said, "It shouldn't have an impact, right?" If it's beyond the planned height, just continue to test like this, and it won't have an impact anyway. ”
"At that altitude, there are no satellites that will be affected."
Zhu Qiqiang nodded, connected to the main control compartment of the engine, and explained, "Taxi rises to stable hovering." ”
The next step is to synchronize the hover test.
Synchronous hover testing is a time-consuming testing process that lasts more than 12 hours.
The future aerospace carrier is likely to hover at a high altitude for a long time and be in a state for a long time, and of course this state will have to be tested more finely.
In the process of synchronous hover testing, they need to test the electronic system and various types of equipment, as well as the overall performance.
The testing process even includes a burst start test, which involves having the engine start suddenly and move quickly to one side for some distance.
During the synchronous hovering test, the engine hovers in a fixed position, and its speed is naturally far from catching up with the satellite at the same orbital altitude.
The speed is probably only about 550 meters per second.
At this speed, it is impossible to rely on its own speed to hover synchronously, so it is necessary to open the light pressure nozzle to provide a certain amount of upward power for the engine.
