1170: C1170 Launch a Synchronous Satellite

C1170 Launch a Synchronous Satellite

Communication satellites are a special kind of satellite that's used to transmit signals. Communication satellites are one of the earliest and most applicable satellites in the world.

As a radio relay station. Communication satellites were like an international messenger, collecting all kinds of "letters" from the ground, and then "delivering" them to users in another place.

If the satellite could remain on the ground, then it would greatly simplify the use of ground users, so most of the satellites were Earth Synchronized Satellite.

At a height of 36,000 kilometers, its coverage was especially large. One satellite could be responsible for 1 / 3 of the communication on the surface of Earth. If three satellites were evenly distributed in the stationary orbit of Earth, global communications other than the north and south poles could be achieved.

When a satellite received a weak radio signal from a geological station, it would automatically turn into a high-power signal. Then it would be sent to another geological station or to another communication satellite. Then send it to another ground station on the other side of Earth. Like this, we received a signal from far away.

However, the difficulty of launching a synchronous satellite is quite high. Up until now, there hasn't been a qualified communication satellite in Han Country, so when Han Country needs it, they need to rent satellites from other countries.

This time, the launch must be carried out.

Currently, in Han Country's country, the launch of satellites was underway.

The Moon City Satellite Launch Center was a newly built satellite launch site in the Han Country. This time, it was its first launch.

Compared to the previous launch site, the latitude here was low, the altitude was high, the angle of the launch was good, and the distance between the ground and the air was short.

The lower the latitude, the closer it was to the equator. This could make full use of the centrifugal force of Earth's rotation, and also shorten the distance from the ground to the satellite orbit, thus increasing the effective load of the rocket.

At the same time, the terrain of the canyon here was good, and the geological structure was solid, which was conducive to the overall layout of the launch site.

In terms of climate, there was a lot of good weather, and it was one of the regions with the least climate change in the country. The sun was as bright as 320 days, and there was almost no fog. The experimental period and the time allowed for launch were much longer.

In short, the latitude here was low, the altitude was high, and there were few clouds and fog, so there was no pollution. The air was very transparent. Now, in a modern and high-tech satellite launch center... At the same time, the only space station here to launch Earth Synchronous Satellite.

It could be said that the space station was built to better launch Earth's Synchronous Satellite. At the same time, there was also Qin Guan's suggestion.

In the aerospace field, they also had to walk the path of being open to the public. They had to accept satellite launch missions, and the aerospace project could also be beneficial.

And aerospace had always been related to military affairs. The previous satellite launch bases had too many military secrets. After the aerospace base was established, it would be open to the public. It would be responsible for the satellite launch mission overseas.

Now, on the launch pad outside, a rocket was already standing up.

Now, the main launch vehicle in China was the Long March 2. The Long March 2 was developed on the basis of East Wind No. 5. It was the Long Conquering Three. It was the third-grade rocket that was developed on the foundation of the Long March 2.

Simply put, its first and second-grade engines used the first and second-grade engines of Long March 2 No. C. The third grade was independently developed and used the world's most advanced hydraulic / liquid oxygen engine. The total length of the rocket was 44. 86 meters. The largest diameter of a core level was 3.35 meters. It could send 1,600 kilograms of effective load directly into Earth's synchronous transfer orbit.

Now, it was its first test flight.

Time slowly passed, and when night came, finally, the countdown began. The launch hall was silent. As the order was issued, the bottom of the rocket began to burn. The entire rocket began to slowly climb up and left the launch platform. It disappeared from everyone's line of sight.

The successful launch had nothing to do with the satellite launch site. What they needed now was to monitor and control.

The entire test and control mission was carried out by the pickaxe capital. In the pickaxe capital, there was a specialized satellite control field.

Although they could not see the spectacular launch scene, they could not see the magnificent and lively scene. However, thousands of commands and a huge amount of data and information from all directions were silently interwoven and running. This place was filled with excitement and excitement, as well as hidden anxiety and anxiety.

In the past, the control center was mainly used to test and control satellites that were returning to the surface. In order to successfully bring the satellite back to the surface, it was inseparable from the control center.

Now, their mission was also very important to allow the satellite to accurately enter the orbit.

Since the first artificial satellite in Han Country flew into the sky in 1970, all the satellites in Han Country had been launched. Tracking and observation, remote control, operation management, information exchange and data processing, as well as posture control, were all under the responsibility of the center. In the mission of returning satellites, relying on precious dedicated spirit and excellent control technology, it allowed the recovery rate of the returning satellite to reach 100%.

Now, they absolutely could not fail either!

At this time, on the ocean, the three sea Surveying Vessel were also working at full strength. Gazing at the distant First Aperture aimed at the space above their heads, capturing the incoming satellite at any time.

The ten thousand tonnes Surveying Vessel opened up its deceleration fins. The antenna at the top did not move at all, capturing the satellite in space.0

As long as one learned the knowledge of artificial satellites, one would know that there were three orbits, a low-Earth circular orbit, a large oval-shaped orbit, and a large circular orbit of a synchronous satellite.

At this time, Qin Guan came to the far-view one and listened to the people beside him introducing the launch knowledge of synchronous satellites.

He was very familiar with it the last time. Colonel Chen was in charge of the entire monitoring project. At this moment, the satellite had just flown over the top of his head. "The posture is normal. It's still in the big oval orbit." Colonel Chen said, "The most important step for us to launch the synchronous satellite is to ignite it in the air."

After a day and night of continuous fighting, the control system had accurately measured the satellite in the sky. At the same time, through the thousands of instructions sent to the satellite, the orbit of the satellite, its position, the speed of the satellite, and so on. After repeated control and adjustment, the satellite had been adjusted to the best position to wait for the ignition according to human will.

The satellite was already in the elliptical orbit, which was also called the transfer orbit. In this orbit, it had to be ignited again.

The distance was 36,000, and it had reached the synchronous orbit. However, the distance was only a few thousand kilometers, so it had to be ignited in the distance to enter the large orbit.

There was a huge risk in this ignition. If the "ignition" command on the ground could not be issued, or if the command was issued, the satellite's engine would not be ignited. The satellite would only be able to continue 'wandering' in the large oval orbit until it fell.

In the launch of Earth's synchronous satellite, many satellites were ultimately defeated at this step.

"Who will send this command?" Qin Guan asked.

"It's our Distance No. 1." Colonel Chen said.
