Wu Hao did not attend the technical seminar in the evening. On the one hand, he was busy with his own affairs and had no time. On the other hand, it was naturally because he did not need to attend such a meeting.
It was approaching nine o'clock in the evening, and when Wu Hao brought Zhang Jun and others to the Xinyuehu Aerospace Command and Control Hall, Luo Kai and Wan Hongfei were already seated, and they had obviously been here for a long time.
After saying hello to a few people, Wu Hao immediately took his seat and looked at the big screen. At this moment, the middle information on the big screen was an expanded world map, which showed the operation of the Environmental Sanitation-1 high-speed orbital debris cleanup experimental satellite.
The actual orbit path. There is also a red orbit path, which is the weather satellite that was scrapped due to malfunction and is about to be tested in an attempt to capture.
The left and right sides of this world map display content respectively. The right side mainly displays some data information, while the left side is the sky image captured and transmitted by the high-definition camera on the satellite. In addition,
There are also various detection equipment carried by satellites, lidar, millimeter wave radar, and various image information transmitted back by optical detection equipment.
How is it going? Has it reached that stage? Wu Hao asked Yu Chengwu, the commander-in-chief of this experiment.
The two satellites are currently one kilometer apart and can start capturing this retired satellite at any time. Yu Chengwu said to Wu Hao and everyone present.
Let’s get started. Wu Hao waved his hand and said.
Yes! Yu Chengwu responded and immediately began to issue instructions.
Satellite commands are issued,
The satellite system is operating normally, information transmission between the satellite and the ground is normal, and image transmission is normal.
The satellite begins to change orbit!
As the command was launched, the center of the large screen began to show the perspectives of various surveillance cameras on the satellite, as well as the impact information of the detection equipment. In the surveillance screen, gas was ejected from the engine nozzles of various parts of the satellite, and the attitude of the satellite was being rapidly adjusted.
As the main engine of the micro-eruption ignited, the speed of the satellite became significantly faster, and the distance to the target satellite became closer and closer.
At this time, Yu Chengwu also introduced to everyone: "You must be extra careful when approaching this retired weather satellite, because the data we detect may be inaccurate.
This satellite has been out of service for seven or eight years due to malfunction, and we have no way of knowing whether its orbit has changed. What we have obtained is the relevant detection data from the previous seven or eight years, as well as ground telemetry data information.
It is unclear how far this data information differs from the actual position of the satellite. In addition, seven or eight years have passed, and we have no way of knowing what state the satellite is in now.
Therefore, this requires us not to rely solely on ground data support. We need our Environmental Satellite 1 high-speed orbital debris cleanup experimental satellite to use its millimeter-wave radar, lidar, and image recognition systems to autonomously detect and identify targets.
Please take a look at the target object information detected by our lidar. Judging from the lidar detection data information obtained so far, this weather satellite is relatively complete as a whole and should not have suffered much damage, so it is still relatively
Easy to catch.”
While Yu Chengwu was speaking, the large screen showed that the Environmental Satellite 1 high-speed orbital debris cleanup experimental satellite was getting closer and closer to the meteorological satellite.
However, because it is over the day hemisphere at this moment, the image is completely black. Intelligent detected its general shape through lidar and millimeter wave radar.
Turn on the searchlight.
clear!
As the command was issued, the searchlight on the Environmental Satellite 1 high-speed orbital debris cleanup experimental satellite turned on. However, what everyone saw was the dark universe, and the damaged and decommissioned weather satellite had not yet been seen.
Lidar shows that the Environmental Satellite 1 high-speed orbital debris cleanup experimental satellite is very close to the meteorological satellite, only three to four hundred meters.
Environmental Sanitation 1 begins to slow down!
The deceleration is successful and gradually approaches the center.
After seeing it, someone in the hall suddenly shouted excitedly.
Sure enough, everyone finally saw a bright spot in the dark picture. It was very small. It was the light of the searchlight reflected by the satellite, and everyone became excited about it. In such a dark space, there is basically no bright spot to be seen.
Yes, this bright spot must be because there is an object ahead. Compared with the lidar detection data, it must be the scrapped weather satellite.
"Watch your speed!"
Even though he was excited, Yu Chengwu ordered very calmly. He understood that the more critical the situation is, the less one should take it lightly.
Under the command of Yu Chengwu, the Environmental Satellite 1 high-speed orbital debris cleanup experimental satellite got closer and closer to the scrapped weather satellite. Under the illumination of the searchlight, everyone finally saw the whole picture of the satellite.
Because the satellite has been scrapped, it maintains a normal attitude. The entire satellite is in a rolling and flying state, which is basically a CNC state.
Come closer, pay attention to your speed, pay attention to your distance, and slow down!
The Environmental Sanitation-1 high-speed orbital debris cleanup experimental satellite continues to approach, getting closer and closer to the scrapped meteorological satellite. Under the illumination of the searchlight, the insulation film wrapped on the satellite still maintains a shining golden appearance. This is
A weather satellite is cylindrical in shape, with a large antenna and two solar wing sails.
It's really a pity. If it was our Savior 1 that went up this time, then the satellite would have a good chance of returning to normal. Wu Hao looked at the weather satellite on the screen and said with regret.
Wan Hongfei didn't speak after hearing what he said. The person who spoke was Luo Kai. He smiled and said: "It's been almost 20 years since this satellite was launched, and it's been seven or eight years since it was decommissioned. Even if it's repaired, it won't be able to survive."
It’s of great use. It’s better to capture it, clear the orbit, and launch a more advanced satellite.”
That's right. After hearing Luo Kai's words, many experts present also nodded.
This is indeed the case. It has been twenty years since this satellite was launched. Its related technology has fallen behind, its performance cannot meet current needs, and it has lost its use value. It is officially because of this that the relevant departments will approve them.
This experiment.
Even though this satellite has been out of service for seven or eight years due to malfunction, it actually still has a certain value. As long as it exists, this orbit exists. And this satellite can also play some other roles, such as becoming a certain
A good target for anti-satellite or anti-missile weapons.
Therefore, if it were not for the support of the military, they might not be able to carry out this experiment.
"Reporting that the Sanitation No. 1 is at a synchronized position thirty meters away from the target satellite. The satellite systems are operating normally and the capture experiment can begin."
