Chapter 1822: Self-confidence

The launch of the base began almost before dawn.
This is the coldest time on the Gobi Desert. The darkness before dawn is so uncomfortable. At this time, even if you wear thick clothes, you will be frozen through. However, the strong wind that has been blowing during the day Disappeared, a rare launch window.
"Fuel refill!" All the commands are being carefully executed. When the fuel is refilled, it almost means that the launch is irreversible. Although the fuel can be pumped out, it is definitely more dangerous than launching. Much larger.
Up to now, the highly toxic unsymmetrical dimethylhydrazine still used by the Long March 2 rocket is used as fuel, and the refueling personnel are fully armed and working with gas masks. On the launch tower, they started the refueling operation.
Of course, a new generation of rockets is being developed, and future rockets will use liquid oxygen kerosene engines. This kind of engine should be more friendly. In addition to being non-toxic, it is easier to obtain fuel.
Kerosene is derived from petroleum, and high-quality aerospace fuel can be produced through petroleum smelting plants. As for liquid oxygen, it is also easy to obtain. It is produced by liquefying air. Through different liquefaction temperatures, the nitrogen in the air After the separation, the rest is oxygen. As for the rare gas inside, mixing in it will not cause too much harm.
Qin Guan is looking forward to that day, but before that, he still needs to do a good job in the current launch. It must be successfully launched!
"Thirty minutes countdown."
After the filling is completed, various checks are started. At this time, the big screen is showing one by one data, and below, there are many small screens. The technical experts are carefully analyzing. The challenger has just exploded. If it happens, they must ensure that their rockets are intact, and there must be no problems!
The atmosphere is tense. Ruo Xi is lying in Qin Guan's arms and has fallen asleep deeply. After all, she is just a child. After a long journey, she has visited many places here and is finally tired.
The countdown number has already begun to ring. At this moment, Ruoxi suddenly opened his eyes and looked at the big screen. The image of the rocket is displayed on the big screen. The red sun in the east is slowly rising. At the beginning, the golden sunlight gave the whole rocket a golden light. On the fairing on the top of the rocket, the bright national flag was so dazzling.
The countdown counts to zero, and then the ignition is on!
When the sound of the final ignition sounded, the operator pressed the ignition button. On the rocket launch pad, a brilliant light was immediately emitted. The Long March 2 rocket with four bundled boosters continued on the launch pad. After staying for a second, it started to rise!
The ignition is successful!
If it is in normal times, if the ignition is successful, everyone will start cheering, but now it is not working. Although the ignition is successful, the satellite has not yet entered orbit. Didn't the Challenger explode after launch?
Everyone is waiting, waiting, the picture on the big screen has disappeared, only one bright spot and two lines are left. One is theoretical and the other is actual. The two lines must overlap. .
Now, everyone is looking at these two lines. The bright spot continues to rise, forming a new curve, which perfectly coincides with the theoretical curve.
"The booster disengaged."
"The first-stage rocket broke away."
"Secondary rocket ignites!"
"Stars and arrows are separated!"
"Beidou-2, successfully entered orbit!"
"Wow!" There was applause at the scene. These were all sent by the personnel of the foreign inspection group. They watched the satellites of Han successfully enter orbit with admiration and envy.
However, the people of Han were not proud, because this time it was two stars with one arrow.
"Attention, start the engine and change rails!"
"The change is successful!"
Each voice is mechanical, but in this mechanical voice, everyone feels the confidence of a big country.
Then, continue to fly for more than ten minutes, the second satellite, separated from the rocket!
"Beidou-3 successfully entered orbit, and now the command is transferred to the capital."
After finishing the last step, everyone got up from their seats, they jumped and cheered.
"Successful, we succeeded!"
"Awesome!" Ruoxi's experience was also extraordinary. She was very happy listening to the cheers of the entire command hall. She was proud of her motherland.
"Congratulations," Swangerang said.
"For us, this is just the first step in the Long March." Qin Guan said: "After our two satellites are in orbit, the next test will be carried out. Everyone knows that there must be at least three satellites. If two-dimensional positioning is possible, we will launch a fourth satellite in the future so that the altitude can be measured and the satellite positioning task is completed."
The principle of satellite positioning is not difficult. When it comes to realization, the main difficulty is the high-precision atomic clock. As long as these technologies are overcome, coupled with computing power, you can easily know your position. In future generations, it will only be so small. A small chip can complete the entire positioning capability.
"Your progress in the field of satellite navigation is even more impressive," Swangerang said.
"We are for the benefit of all mankind." Qin Guan said: "Our satellite navigation signals are fully open, and we will not conduct man-made interference. Military and civilian signals are of the same order of magnitude. We strive to Let it achieve an accuracy of ten meters, and then gradually upgrade to an accuracy of one meter. This is our contribution to the world."
Satellite navigation can do too many things. Car navigation and mobile phone navigation have made people become fools. Just follow the navigation. Of course, it also needs the cooperation of digital maps.
In addition to this common function, there are still many other applications. The most direct and effective is low-cost precision guided weapons, which are called JDMA bombs in Eagle Country. Just add control components and satellite receivers. , You can fly to a fixed target accurately.
Your own side is for the benefit of all mankind. Of course, it is a rhetoric to expand your own market share and let the whole world use it. In this way, your own side has the dominant power. For example, in a war, your own side can block the area at any time. The signal made them fall into chaos.
Now, it is competing with GPS. The most uncomfortable thing about GPS is that it has high accuracy. However, people have increased interference and lowered the accuracy by one level.
We don't interfere, we just do it for the benefit of all mankind. Everyone uses it together, and we use Beidou receiving terminals. In this way, the entire ecosystem is established.
When that time comes, one's own side has the absolute right to speak!
