Satellite frequencies mainly refer to the part of the radio spectrum used for space radio services.
The information sensing, information transmission, and measurement and control units of any satellite system require the use of the electromagnetic spectrum.
Different frequency bands have different propagation losses. For example, the "radio window" refers to the 0.3 to 10GHz frequency band with the least loss. The "translucent radio window" refers to the frequency band near 30GHz.
With the increasing number of satellite application scenarios and functions, the limited resource of satellite frequency resources is naturally used less and less. At the same time, because satellites must use a certain orbital position in outer space during operation, resources are limited whether it is a geostationary orbital position or other orbital positions.
For the sake of maximizing profits, some Guo Jiahe organizations started frantically registering and delivering junk satellites.
Some countries, including Neon, India, and Korea, have independently or jointly manufactured communication satellites to seize orbital resources.
"Crashes" and the need for coordination among satellites from various countries often occur.
As of 2023, the United States still ranks first in the global ranking of satellites in space, with approximately 1,950 satellites in orbit. The second-placed Rabbit has only more than 600 satellites in orbit. Other countries combined do not have as many satellites as the top two combined.
Mao Xiong actually has hundreds of satellites, but half of them are old satellites that have exceeded their service life...
Although the field of low-orbit broadband satellites has just started a few years ago, there are still many people vying for space in this project.
When foreign giants began planning low-orbit broadband satellites a few years ago, why didn't Gu Qing want to get a piece of the pie?
However, the threshold of the aerospace industry is too high, and it is not something you can do just by having money. If you want to make great strides in this industry, massive funds are a necessity, as well as a large number of relevant professional talents and supporting technical products are necessary factors.
Daxia is the aerospace field that was opened in 2014, allowing market-oriented means to enter this industry. However, in this industry today, except for Jiuzhou Technology, which relies on official help and is developing well, other private enterprises still need to be strengthened.
In addition to being equipped with "defensive equipment", Jiuzhou Technology's satellites can also climb and move down in space orbit. They are "able to both fight and run" and have quite a bit of guerrilla skills. Therefore, Jiuzhou Technology's aerospace department is affiliated with Some people within the satellite R&D and manufacturing department of China call the satellites that will be used for regional networking today a guerrilla network.
Although it is a joke, I may not have thought about "fighting guerrilla" at some point.
The special titanium alloys and polymer materials developed by the Titanstar Materials Department give these guerrilla satellites high strength, high temperature resistance, corrosion resistance, and the advantages of being flexible and light. Their maneuverability is far superior to other satellites of Guo Jiahe Company.
As one of the chief engineers of Jiuzhou Technology Aerospace, Li Jian reported the latest situation to Gu Qing.
"The final assembly test has been completed and the official application has been approved. Mr. Gu, please light the fire."
After saying that, his eyes fell on the special button on the control center console.
Other engineers, academicians, doctoral supervisors, and technicians present also unanimously focused their attention on Gu Qing.
Because of the man in front of them, they will continue to rekindle their enthusiasm for Daxia's aerospace industry, instead of being stuck in the quagmire of human accidents and intrigues and academic fraud.
I no longer have to be tricked by my boss into helping the children of my "mentor" with their projects.
If the project wants funds, just write the report and plan directly, and sometimes the budget you get is even bigger than the pie you drew...
For such an "outside the industry" who so firmly supports their career and others, they are willing to put this special event symbol on Gu Qing.
Faced with everyone's expectations, Gu Qing looked around without hesitation.
Xuanwu also made simulation animations for the projection of SR1 glasses to help its creators better complete this step.
"Only by believing in the future and working hard towards it can we finally get the future."
mind
With emotion, Gu Qing placed his right hand on the button in a hurry.
The old academician Li Lun stood nearby and subconsciously squinted his eyes. He seemed to see many familiar shadows on Gu Qing in his field of vision. Those people who have been recorded in history have never disappeared in Daxia. .
The tactile feel of this special physical button is different from that of keyboards, mice, and button phones. It has a very obvious sense of damping and clear feedback at every level.
Determine the identity of the presser, press down, and determine the function.
emission!
Although the signal transmission was very fast, Gu Qing's keen senses still felt a slight delay, but it was precisely because of this delay that he felt the reality.
boom!
Even to protect surrounding facilities, Jiuzhou Technology's launch pad is equipped with a large pool. When fuel is injected, a large amount of water will be directly vaporized into water vapor by the high temperature of the injector, while absorbing noise.
But human beings’ yearning for space cannot be concealed by water.
After hearing the roaring noise of liftoff, the high-temperature water vapor generated when the rocket was launched liquefied into small droplets when it came into contact with the cold air of Xishu, becoming the white gas that the rocket soared into the clouds.
The sharp arrow that shoots through the sky carries the three most important core communication satellites of Jiuzhou Technology’s 6G regional network experiment this time. It also carries information from Jiuzhou Technology’s aerospace department, 6G communication engineering department, Titan satellite department, and semiconductor department. Hot wish.
The 130-ton rocket power unit independently developed by the Sixth Institute of Daxia Aerospace Science and Technology Group uses a reusable liquid oxygen kerosene afterburning cycle engine to apply thrust frantically to accelerate the rocket.
When the first stage of acceleration is completed, the rocket enters breakaway speed.
At the same time, some rocket components also began to detach. In the twinkling stars, multiple engines and equipment began to operate according to the program. The command center and intelligent programs controlled the detached components to land, while the main part of the rocket began to enter the next stage, heading outside the earth. Orbit away.
If it was ten years ago, the launch command center would have been cheering at this time, but since all recyclable rocket technology is used now, everyone still needs to be patient and wait for the success of the recovery process.
Gu Qing looked at the rocket rising across the sky and heading towards space, feeling suddenly a little sad in his heart.
When he left the earth, did his soul also ascend into the sky and become a star? Or did you say you traveled directly to this blue star?
With a planet and universe so similar to the earth, I have set foot on the sea of stars. Is it possible to see that familiar planet again in the future?
