From University Lecturer to Chief Academician

The fault reported by GISAT-5A caused a mess in the satellite center of X3.

GISAT-5A is so important.

This large-scale optical reconnaissance satellite was manufactured by a third-party space research organization. It used expensive imported high-end optical equipment and electronic system equipment, costing a total of nearly 700 million US dollars.

In comparison, it is already quite expensive.

The cost of international high-end large-scale optical reconnaissance satellites is only between US$200 million and US$400 million.

GISAT-5A spent so much money and was independently developed by a three-dimensional space research organization, which also has a certain representative significance.

At the same time, GISAT-5A is also the most high-end reconnaissance satellite of a certain three armed forces, and it has strategic issues that are directly related to the military's reconnaissance capabilities.

Problems with GISAT-5A are not what they want to see. If they want to build another satellite with the same performance, it will not only cost a lot of money, but also need to wait for a long time.

Amid the panic among the satellite center staff, one leader asked angrily, "How did the satellite go wrong?"

Satellite center personnel reported, "There were two failures, one was a sudden orbital deviation."

"We did not turn on our own power system and did not make orbit adjustments, but GISAT-5A suddenly experienced an orbit deviation, and the deflection angle was still very large..."

"The failure reported by the satellite is the big problem. The orbit deviation can be readjusted, but the solar panel damage may cause the satellite to lose control!"

"This kind of failure occurs very rarely, and there are only two known incidents in history. One was American's reconnaissance satellite, and the other was the geosynchronous orbit satellite of the former Goose Alliance."

"The failure of the Amerikan satellite was determined to be caused by a failure of the power system."

"Is there a quality problem with the satellites of the former E-Link, or was it fifty years ago..."

The staff at the satellite center explained.

Damage to solar panels is a rare failure, because solar panels have very low technical content and all technology is reflected in material performance, so the possibility of failure is very small.

Conventional satellite failures are generally power supply failures, transmission system failures, orbit control failures, and payload system failures, all of which are linked to electronic systems and can be self-checked and repaired.

If the solar panel is damaged, it is most likely to be physical damage, and self-inspection and repair cannot be carried out at all.

"Is it a quality problem?" someone asked speculatively.

The high-end weapons and equipment they independently develop often suffer from failures due to poor quality.

Even in the aerospace field with high technical precision, similar problems occasionally occur, but they are less common than in other fields.

Someone immediately denied, "It can't be a quality issue."

"This is not a separate failure report. The satellite also experienced an orbital deviation. Both occurred at the same time."

"The solar panel is just malfunctioning, not falling off, and will not affect the satellite's orbit."

"We don't know the specific fault situation yet, we can only wait for the satellite to send back photos..."

Others can only continue to wait.

GISAT-5A is equipped with high-precision optical equipment. After adjusting the camera lens, it can capture damaged solar panels and send back high-definition photos.

However, GISAT-5A is not a communication satellite. The radar communication system is relatively poor. All digital information is transmitted back. To receive the information and convert it into photos, you need to wait for at least an hour.

soon.

American also knew the news, and they immediately realized that the situation was unusual.

"It's not a coincidence!"

"GISAT-5A malfunctioned about 80 kilometers away from the light source engine."

"The orbital deviation and solar panel damage occurred at the same time. Our analysis believes that the chance of coincidence is very small."

"There is more than 90% possibility that it is related to some kind of space weapon technology of the flower growers, or to the light pressure engine itself."

This is what a quick analysis concluded.

In fact, there is no need to analyze it carefully at all. Just think about it and you will know that the situation is unusual.

The probability of a satellite failure is very low. How come it suddenly failed when it was close to the edge of the space control area and closest to the light pressure engine?

"The question is, how do they do it?"

"We did not detect energy anomalies. The light pressure engine did not emit laser weapons, and the satellite directly malfunctioned..."

"It still depends on the damage to the solar panels. We can analyze it based on the specific situation."

"How long will it take for Xiansan to analyze the photos?"

"About an hour."

A satellite center staff suddenly reported, "We found that the orbital deviation of GISAT-5A is very similar to the TSA-395 that crashed last time."

"Both satellites suddenly experienced orbital deviations, as if they were suddenly subjected to some special force."

This information further allowed American to determine that the malfunction of GISAT-5A was directly related to the flower grower's mysterious space weapon technology or light pressure engine.

Testing of the light pressure engine continues.

Zhao Dahe operated the engine to approach GISAT-5A, and after performing the gravity shield interference satellite mission, he couldn't help but breathed a sigh of relief and said to the other two people, "We actually hit a satellite."

"Although it's not a direct blow, it's still a big impact."

"If I can tell this in the future, this matter will last a lifetime..."

"yes!"

The other two people were also very emotional. They had 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 for a few words and then continued to focus on their work.

The next task is to release the v191 satellite.

Satellite release is very important. Cooperation with the military is one aspect. Spaceship companies also hope to take advantage of the opportunity to announce to the world that they have the capability to launch and release very large satellites.

The process of satellite release will also be broadcast live to the whole world.

The live broadcast of the light pressure engine space test continues. The engine has completed takeoff acceleration and has risen to an altitude of nearly 600 kilometers.

It seems to have taken a long time, but in fact, it only took a total of more than an hour, including preparation and take-off time, and it was only half an hour from liftoff to now.

Most people who watched the live broadcast were not aware of the problems with GISAT-5A, and even said that they did not know that such a satellite existed at all.

They are just paying attention to the test of the light pressure engine and waiting for the upcoming satellite release.

After interfering with GISAT-5A, the light pressure engine did not return to its original orbit, but only slightly adjusted its direction and continued to accelerate.

When the established speed and direction are reached, the work of releasing the satellite officially begins.

Live broadcast screen connection.

At this time, the picture has changed to the perspective of space, and the live broadcast picture was taken by several high-definition cameras that come with the light pressure engine.

The viewing angles of several high-definition cameras can be continuously switched to provide a live broadcast with a clear viewing angle, which also surprises the audience watching the live broadcast.

Various countries have launched many satellites into space, but it is rare to see the satellite release process 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 showcase high-end space technology, nor is it because the satellite release process is unattractive, but because ordinary satellites do not have the ability to transmit data quickly.

Simply put, the data transfer speed is seriously insufficient.

Even if the performance of the built-in camera is good, the data cannot be transmitted in time, so it will not be possible to watch live.

The light pressure engine is different.

The engine is equipped with first-order radar equipment, as well as other high-end information processing and transmission equipment. The data transmission speed is very fast. Data can be transmitted with high precision and without delay, and high-definition live broadcast can be carried out.

Just by watching the live broadcast, professionals can analyze a lot of things.

"They're using digital signaling."

"The picture is very clear and stable, without any lag, which shows that the transmission speed is very fast."

"This is very unusual..."

Generally, there are two ways of data transmission, one is digital signal transmission and the other is analog signal transmission.

Generally, the videos you watch are all digital signal transmission, which can have a high resolution and the picture will be very clear. However, the problem is that digital signal transmission is easily interfered by the atmosphere and other radar signals, and the transmission process may be unstable. .

It is difficult to achieve sustained high efficiency and stability in digital signal transmission from space to the ground.

Another method is analog signal transmission. Analog signal transmission will also be unstable, but it can provide a continuous picture. However, when the signal is unstable, the resolution will be greatly reduced, and the screen may even appear blurry.

The optical pressure engine can achieve such stable and efficient data transmission, which also represents extremely high-end data transmission technology.

American judged, "It is likely to be some kind of high-end information transmission technology, possibly related to first-order electromagnetic waves."

"This is also evidence that they have mastered first-order radar technology!"

In the live broadcast, the work of releasing the satellite has begun.

From the perspective of a single-sided lens, the light pressure engine surrounds the cabin. A small part opens the cabin cover, and the large satellite slowly rises from the cabin.

When it rises to a certain height, you can clearly see that the large satellite is connected and controlled by a V-shaped boom, which is somewhat similar to the boom of an excavator.

The satellite was hoisted away from the cabin, about forty meters away, and the V-shaped boom was extended to its limit.

The fixtures at the boom and satellite connections are opened.

At this time, you can see the satellite trembling, a power tail appearing behind it, and the satellite beginning to accelerate away from the boom.

The next picture you see is that the satellite is moving away from the light pressure engine.

Soon disappeared from sight.

The First Media host introduced, "Next, the satellite will rely on its own power to go to the predetermined orbit..."

The satellite release work has ended.

Whether subsequent satellites can reach the established orbit and operate normally is a problem of the satellite itself and has nothing to do with the launch and release of the satellite by the light pressure engine.

Many people in the Internet public opinion also began to celebrate, "The satellite release was successful!"

"Congratulations on the success of the light pressure engine in releasing the super large satellite and the phased success of the engine test..."

"Humanity's satellite technology can enter a new chapter with this!"

Ordinary people just shouted as if to join in the fun, while companies in need of satellites began to consider manufacturing very large satellites.

The larger the satellite, the greater the performance it can achieve.

If very large satellites with tens or hundreds of tons can be manufactured, the performance of satellites will definitely be greatly improved.

The only problem is that we don’t know whether the light pressure engine can help launch geosynchronous orbit satellites. Geosynchronous orbit satellites are mostly used in the conventional commercial field.

For example, the field of communications.

Satellites used in the communication field need to be pointed at one position for a long time to ensure the stability of communication.

The altitude of geosynchronous orbit satellites exceeds 35,000 kilometers. Launching geosynchronous orbit satellites generally requires a climb of more than 30,000 kilometers.

After that, the satellite can rely on its own power to continue climbing 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 away.

In this regard, we still need to communicate with the spacecraft company to see if relevant cooperation can be carried out in the future.

After performing the work of releasing the satellite, the light pressure engine continued to climb upward. The engine adjusted its direction to face the earth's surface, and then continued to glide upward based on the existing speed.

Ground control room.

Zhu Qiqiang reported on the engine condition, "Based on the current speed, the engine is expected to rise to an altitude of 1,230 kilometers, which is more than 100 kilometers higher than planned."

This is mainly because the sudden execution of the task midway 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 any impact, right? It's beyond the planned height, so just continue testing like this. It won't have any impact anyway."

"There are no satellites that would be affected at that altitude."

Zhu Qiqiang nodded, connected to the engine main control cabin, and explained, "Glide to a stable hover."

The next step is to synchronize hover testing.

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 certain altitude for a long time and be in one state for a long time. Of course, this state must be tested more carefully.

During the synchronous hover test, they need to test electronic systems and various types of equipment, as well as test overall performance.

The test process even includes a sudden start test, which means the engine is suddenly started and moved quickly to one side for a certain distance.

During the synchronous hover test, the engine hovers at a fixed position, and its speed is naturally far slower than that of satellites at the same orbital altitude.

The speed is probably only about 550 meters per second.

At this speed, it cannot rely on its own speed to hover synchronously, so the light pressure nozzle must be turned on to provide a certain amount of upward power for the engine.
